Big or small blocks that run harder than they have the right too!

How many runs, how many wins, how much are you hated at the track ? 😁😂😁

I’ll start it off with a low dollar build.

 

ran a few different small blocks in this .

best et/mph was with a dirty dog 403. Stock bottom end with the scalloped crank, cast pistons, J heads , perf RPM, mild hyd flat tappet, 400t 3k converter with 4:56’s, full interior, power windows, T tops, 3580 race weight. 11.57@115 1.51 60. Would carry the wheels a few feet.

Super consistent…left it in drive and let it shift on it’s own. Over 4000 runs on the engine back then. Sold it to a guy who continues to run it on the street.

 

i got nothing

But cool 442!!! it looks mean just sitting there

 

I like it!

 

My high 11 sec NA 327 shop truck-

 

I think I only had 3-4K total in this engine( I lucked out on a rebuilt 350 .030 over, balanced short block cheap), never had it down the 1/4 mile but I beat a 55 Chevy with a built 454/4 speed so bad he put twin turbos on it.

 

Just a 350 .030 over. 10.25 to 1 compression still run pump gas , solid flat tappet cam , #6 iron heads , Holley street dominator intake. Th350 4500 stall , 3.90 gear. Best run is 11.62 @ 112 with a 1.56 60 ft. I think there maybe a total of 4k in the engine. The short block was a hand me down with probe pistons that I freshened up and had re balanced , the heads where done by a friend in trade for some body work , intake was welded up modified for a 4150 flange and ported as well. I'm running a freebie solid flat tappet ultradyne grind. The trans was a friend's old race unit that has been the best 350 bucks I have spent then I bought his old 4500 stall for 250, the rear end was build by a local racer and is just a rebuilt stock posi and GM 3.90 gears .

Engine has maybe 2k street miles and about 200 runs just for fun an a bunch of random bracket races . I just started running sportman and have to hold the car back to 12.0 but it runs the number pretty consistent . First time out I went into the semis.

 

What a cool clean looking truck. Bandimere times?

People hate losing to an Oldsmobile. Chevy guys in particular.

I love everything about your car. You already know my feelings about your paint work. And it hauls ***. And you let it!!!

 

Definitely not Bandimere times, 11s ran in 1400 DA. Actually the body is quite rough, but original paint and I like it rough, don't have worry about paint chips because I drive it a lot. Its been fun!

 

3-4k? I guess someone gave you the supercharger?

I'm the slow guy that spent too much.

 

Basically, I paid $100 dollars for that turbo.

 

I assume that 327 is a short stroke engine ?. Details on combo. I'm a big fan of the 327 .

 

oh, pic looked like a Vortech

 

Its a 1967 327 small journal, 4.030 X 3.250, 480 lift 240 @.050 SFT on a 108, 462 double hump heads, 2.020/1.60 valves, Performer RPM intake, 750 Holley. 445 HP, 400 TQ.

 

Wasnt there long stroke version. And a big reason the 331 was so popular as a combination was the big bore short stroke combo ( similar to olds ). I wanna say 3.25 vs the olds at 3.385 with a stock 4.057 bore. I always wondered if anyone did a de stroked olds or if that could even be a thing.

 

that’s neat

let’s here about the set up. What turbo is it?

 

Reminds me of an electrical contractor customer I had while installing stereos. He pulled into the install bay with his beige chevy truck with the rack on top one day and asked if anyone wanted to race his "ol' shop truck". I had a big block Camaro at the time so I said why not. He then popped the hood and said open it up. I found a 590 Donovan under the hood of his "ol' shop truck"! Then he opened the lid and showed me the NOS bottle that ran side to side of the tool box in the bed. I rescinded my offer to race him. It may have been a big block, but just a stock, refreshed, 403 with a mild cam. I think it was the inspiration for the "Farm Truck" from Street Outlaws!

 

i normally like to just lurk in the background with my popcorn but it’s been slow in the racing section. Here is a list I wrote after the engine was done. The turbo is a gm turbo off a 6.5 diesel. Cam is 227/227@.050 .540 lift with the 1.65 rockers. Heads were small valve 7a(‘72 small block).

350 sbo, .030 over;

Custom Erson cam

Cloyes true double roller chain

Trick flow pushrods

Comp cams guide plates

Scorpion roller rockers, 1.65 ratio

Valve springs to match cam

Heads shaved and pocket ported, 9:1 comp

Holley street dominator intake

Hamburger 1" tapered spacer

Quadrajet rebuilt for blow through with parts and help from cliff Ruggles.

Extreme velocities divided hat

Tial 50mm blow off valve

Borg warner turbo with banks boost controller.

k&n filter, draws cool air from outside of engine bay

3" down pipe splits into dual 2.25" pipes

the turbo was to small for my goals, stopped going faster around the 15psi but I tested up to 19psi. Probably only made 400hp( I’d guess 440 max with the pre and post turbo meth injection). I sold the car but kept the engine and have slowly been rebuilding it with better heads, intake, cam, and will be using a holley next time around.

 

At 2017 I built 4.155" x 3.57" SBO. Engine costs around 5000€ (~5700USD at the time).

Mahle Ford pistons, 1,1,2mm rings
330 Offset ground crank, nitrited, internally balanced, no heavy metal needed.
Eagle H-beam Chevrolet rods, 6.250", for 1.88" Honda journals.
#7 heads, ported to death, 62cc chambers, intake runner cc's 176. CR 11.5:1
235/245 Howards hyd. flat tappet cam, Rhoads v-max lifters, 1.73/1.65 rocker ratios
Victor intake
etc etc

No drag racing here, cutlass '81 flexy chassis, rock hard suspension, ford 8.8 rearend, muchos beefed th200-4R. Built for standing mile fun. Best to date Edelbrock performer RPM on top and less porting was 149 mph, converter (9.5") unlocked. Now, with Victor intake has around 45 RWHP more, 425 hp on wheels @ 6400RPM. 0-100 mph 8.95 seconds with 1 ft rollout, street tires (Nitto 555R).

No way to build that cheap anymore

 

That turbo is what we refer to as a 'B2' frame size. Definitely not the best choice for your combination but I guess for $100 you really can't go wrong. We have other systems available that can insure you meet your power goals. Also, that cobra head on the top of your carb is destroying your flow. I understand space limitations under a stock hood but that configuration should be avoided at all costs.
Not trying to throw cold water on your build - it looks awesome!

 

The Borg Warner gm-2 was definitely too small but it had zero lag and the engine ran real strong for what it was. What’s a cobra head? I had an extreme velocities hat with one inch spacer welded to it.

 

Your comp outlet has a nice large radius bend (the orange pipe in your picture) but then there's a chrome looking piece that changes the direction of your flow by 90 degrees. It may be an aftermarket piece with a cool sounding marketing name but in my world it's known as a 'cobra head'. You want as close to laminar flow from that compressor outlet as you can get. Your set-up looks good until you enter that chrome piece. A lot of OE engine manufacturer's will use these because they decrease the necessary package space but we always discourage it. That being said, your carb is probably your biggest restriction to flow.

 

aka- carb hat? Pressure box (old Paxton design)?

 

Ok, a blow through carb hat. Never heard it called that before. I understand the flow limitations, the spacer was welded to the bottom to give a bit of extra time to “straighten” out the flow before entering the carb. What better options are there for a blow through carb set up?

 

Season 6 Episode 85 of Engine Masters tests 5 hats for blow thru. Spoiler: the CSU took the cake.

 

got a link? Would like to see the tests

 

I give them $50/yr to watch it on the treadmill in the morning. I looked on YouTube; ain't see it....

 

Engine Masters on Amazon Prime over 116 episodes. Just pay the price. You get all the MotorTend family. They do come out on TV every so often. Very interesting, But take it a grain of salt.

92. Screaming 8K RPM!! Basing my AJ Foyt HP DX block build with BTR. Steady horse power right to the max rpm. Bill is great to work with. Giving me what I want. We are the same page. Just can not wait for it. Not low buck

 

do I have to buy a treadmill too?

 

$50 for 116 episodes of daytime soap opera?

I would rather build an engine and take part in an EMC event.

as crazy as that sounds these days …🙄

I am a amateur hobbyist. And do not have the knowage and skill of you. And many other engine builders here. That being said, I do have a thirst for knowage cars on many other subjects. And disassembled and reassembled he SBO engine in my car now. Because of a horrible builder in NC. Run the **** out of it and still ruining great. Done many upgrades to enhance braking and handling on her. The guys on Engine Masters do real world testing. And included the whole MotorTend family shows. I will pay a good waiter $50 tip at one dinner. If she good looking, I try to give her the whole thing, just not the tip. You pay for good service - as pay a great engine builder. $50 is cheap for me to learn.

Screaming 8K RPM!! episode. Is the direction I wanted to go before I saw it. Seeing it, sealed the deal for me! Amateur street racer with Lighting Rods 8,000+ shifting. Maintaining the horsepower to the end of the shift
.

 

1970 350 SBO, .060 over; N crank

Iron 7a with BBO valves installed.
Heads cut to 65cc 10.+ to 1 compression - 2008 Heavily ported & bowl work by me. Test videos at end
7111 intake heavily ported and match with heads, cut divider. Was able to get in deep with flexable dremel tool
All made a huge defferance!

Comp cams Have the old card around, wicked sounding
Valve springs to match cam
Trick flow pushrods new to fit below
Scorpion roller rockers, 1.6 ratio
Comp cams guide plates

Cloyes true double roller chain
Quadrajet 750 rebuild with special jetting by me AU or AX? I tried both. Not sure what I left in.

Hedman long tube headers ceramic coated 1 3/4 in?
Dual 2.25" pipes
Flowmasters
Added dual electic fans
boxed rear contorl arms

This engine is an old 347 cube DX from the 80s. The goal was to not re design unless there was an issue. Most of this remained the same with the exception of getting rid of the .090 wall piston pins , getting rid of the receiver grooves in heads utilizing MLS gaskets, and adding Manton series 5 .140 wall pushrods. This was an assembled short block. Got rid of the lifter oiling modifications and went back to the stock oiling system with BAM lifters. Found a broken ring when I took it apart and had to clearance some pushrod holes that were hitting.

Me-- Be still my beating heart!! I know mine will look like that, but more HP. 8500 rpm- yes!

Me-- What is the Compression on this one? Thanks

Bill-- it would go higher but I stopped. It had old school aluminum rods in it, and springs that I didn't pick out. It will go higher.

Compression 13

 

And I suppose you have no problem with that VE? 228 FHP? LOL Care to comment on this Dale...............................

 

These numbers will not matter when its backed up by down track results like most of Bill T performance engines are.

 

This is only 347 cube that Bill is only rebuilding. Mine will be 414 cubes.

 

What heads on it?

 

Battens

 

The HP per cubic inch I think tells the tale. That's pretty impressive imo for a 347.

 

Very nice!
