Has any testing/racing been done on this 403 Olds combination? Always very busy myself, but that doesn't stop me from developing/testing my current project.
I guess a Troll is a Troll! Social media trolls? They're people who deliberately provoke others online. By saying inflammatory and offensive things. They live to make people upset and angry.
People need to be careful! Fact check many sources! Just don get caught up in the BS going on out there. Do not be sheep!!! Be very informed!
Vortecpro and and Andy Miller need to meet each other for those of you who know that reference 😂😂😂😂
They both sound like a bag of vinegar from the same box 😂😂😂
Actually I do know Andy Miller......................we have talked at length about the performance of cars I've raced, and other things on this forum, and he's got a lot to say. We get along great!
"Your description is very basic as layed out above. kinda gives the impression that its you basic kinda weekend hot rod.
From your picture, et's, stance and some of those front end parts, it's far from your basic or average hot rod and it's far from your basic engine running 9.50's. On the opposite hand it's very cool and impressive. Sharp looker!" Andy Miller
"142.29 is the true indicator of how maximized this application is, if you don't find anymore power on tap, in the engine. A 9.299 et in conjunction with a 142.29 mph is at 100-105 percent efficency. It actually et's better than what the mph indicates, and that means you maximizing your acceleration rate from the hit (home plate) to the 330. On a 1.40 rear tire 60ft, you would be sitting at a 1.25-1.26 60ft if tripped with the front tires, based upon that given power/et range.
The above is a major complement on the ability to maximize and extract the applications best potential.
I have found the following high and lows (HP) come from some of these internal items:
17-28 (vacuum pump)
27-33 (ring package)
10-40 (oil pan design)
When you add it all up, you can safetly use the factor of 20HP per .1 for down track results. If I take the average of the above figures, it comes out to around 78HP. Thats .30 down the race track, which means if all those items went back to "basics", that ride would be a 9.60 player at 3600 pounds, and that gives an understanding of how much time is invested into the heads and manifold. That top end package, even with it being a steel head, is no slouch by any means.
P.S. If that is the Hoosier radial slick, many don't know that it is a bad **** tire. We've tested many slicks of that size, and there is nothing on the planet that we have found, that even comes close to the Hoosier radial. It just flat out flys on a heavy car due to the sidewall construction. They go away quick and they are costly, but you get what you pay for." Andy Miller

Did you just quote someone to pat yourself on the back 😂😂😂😂😂😂😂
Yeah, he is that cool. Hey Velcropro here is my 70S, a $1500 car, very very rough when I got it. I recovered the front seat and headliner. Yes, the 350 needs replaced, also has a 2004R and 2.78 open. The 350 will be replaced with a 403 stroker, machining this Winter. Also have my 88 Cutlass with the painted 73 Olds 350 in the first pic with electric fans and a serpentine belt drive, 2004R and 3.42. It has been to the track, only mid 14's with the 350 in the 70 which is dying, not bad, 10 years on a $120 motor with early ported heads and a cam added. Also have a 88 Cutlass, had at least 15 years, getting too rotten to keep. I have two Olds powered daily drivers, how many do you have Velcropro? The first pic is my Wife's driver and our tow vehicle, pulling our brand new Lund Fury 16', have you seen the fish we catch, big and a lot of them. It is a Go Green 2017 Dodge Challenger GT AWD with every available factory option. It get high 30's Imperial and low to mid 20's towing. Just over 50K with almost 0 issues.

I did, I was surprised when you brought Andy up. Actually some how I've had contact with many of the Olds parts suppliers and higher end Olds engine builders out there from my time on this forum. I'm in the middle of a 455 Olds build right now. Andy and I have been a few rounds before, but we get a long great.

No Olds drivers now, but heres a list of Olds I've owned in the past.
1. 18,000 mile 1970 W-30 D/SA Maroon on white
2. Black on white 1970 W-30
3. 1971 post race car
4. 1971 Cutlass race car
Those are all nice cars by the way. I wasn't going to comment, here it goes. Here is the issue, you insult Oldsmobile guys like Dan and wonder why some us don't like you. You talk about how fast your BBC builds are, no one on here cares. If you can't build a BBC to run fast, you should hang yourself. GM highly favoured chebby. Read the stories of the former Oldsmobile employees how chebby would throw a tantrum anytime Olds or the other divisions built faster cars or more powerful motors. Emissions, upcoming insurance and GM's Golden Child chebby killed the Hemi 455. It would have killed the ZL1 with its 650 hp. Also the F88, twice the car as the Corvette and better than a Thunderbird. Better brakes, handling and a 270 hp Rocket V8 compared to chebby's no flame 6, not even close, the Corvette would have disappeared. Harley Earl made 3 different models, he couldn't believe GM would not make Olds Corvette killer. Speaking of your peanut port heads, what a stupid truck head design. The 454 was a canted valve, big port design meant to breath. I knew one guy who threw a late 70's version in a 78 Camaro. It blew the TH350 then its bottom end, knock knock, a 454 that's who. GM had much better truck motors in the Olds 350 and especially the 455, smallish, long intake runners, ports and a long stroke means torque without trying. The Peanut ports were making a 454 something it was not, a low rpm torque motor. Pretty sure chebby wouldn't allow another brand in their trucks. Many of us Olds guys have swapped in Olds V8's in trucks. I had a stock high mile Vin Y Olds 307 out perform two stock sbc 350's in my 78 1/2 ton, the sbc sucked bad with the 2.76 gears. My 94 with an Olds 350 with 5A 307 heads, 8.5 to 1 204/214 cam and shorty headers, 4L60E and 3.73, out performed any 5.3/4L60E 3.73 trucks I drove, idle to 4000 rpm. With the 454 TBI, would beat them up top too, when it ran right. I had issues with sticking throttle and the TPS. This was with an awful factory sbc swirl port tune. No timing built in, it needed 10 base timing to not backfire through the TBI, settled on 19. Plus it did not like even the small 204/214 cam. A custom PROM was going to be the next move but a faulty circulating block heater burnt it to the ground. GM builds everything for the Corvette and tries to make it fit trucks, doesn't work so well. Finally the Gen 5 direct injection 5.3 with the 8 and 10 speeds aren't awful to drive down low and actually feel like 355 hp with some torque too. I don't care if my Olds are the fastest, our familes best cars we owned were SBO powered and I just love them. Maybe my 424ci 403 build won't live up to your standards but I don't care, it will be fun to drive.

Let me address some of your posting points.
1. I don't wonder why you don't like me, I don't think about that.
2. If your happy with your cars/engines I'am happy as well, enjoy your machinery!
3. Since you brought up my peanut port lets get into that build again.
4. 467 CUIN
5. 9.3 compression
6. 228 @ .050 Hyd cam
7. Stamped rocker arms
8. 4 quart factory oil pan
9. Dual plane intake
10. 585 HP @ 5900 RPM run to 7000 RPM in my car
11. 10.30s @ 126 MPH NA @ 3720
12. A video for your entertainment:
I guess a Troll is a Troll! Social media trolls? They're people who deliberately provoke others online. By saying inflammatory and offensive things. They live to make people upset and angry.
People need to be careful! Fact check many sources! Just don get caught up in the BS going on out there. Do not be sheep!!! Be very informed!
How many hours of porting are in those peanut port heads?
That was a while back but I'd say 6 hours total porting for both heads. Not sure if your aware but a stock 236 peanut port moves more air than any stock production olds head. My Olds 455 build is machined now and is moving into the assembly room, so you should have something there you can sink your teeth into.

So what you’re saying is that it’s really not hard to make that kind of power from that combination. Anybody can do it obviously. It’s nice to know you can admit that you’re actually nothing special.
So with that I have to ask, what’s your point in posting that Dyno pull, other than to solidify that you’re nothing more than a run of the mill Chevy engine builder? Just curious.

So you own a Chevelle but can't be bothered to own an Olds? Obviously, Olds is not your first love, it is for many here. Cutlassefi owns one, with my favorite V8, way more durable factory than any sbc from the same era, an Olds 350, 2004R and yes it has EFI.

I run them in Trans Ams. Lot of hate on the non- Pontiac motors in my circle. For some reason those with LS conversions in Trans Ams get a pass. Must be a Chevy thing....

I own several GM cars, but I really like COPO's wether its a Chevelle or Camaro.

That is BS. Almost everybody gives the LS a pass to go in everything. I sure was never impressed with any Gen 3 or 4 motors in the trucks I drove, they sure weren't good truck motors. I get it they have very strong blocks and good flowing heads. They sure are soft down low, which sucked especially coupled with the fragile 4L65-70E trans.

What are your current GM cars you own? I have been kind of on the look out for a 88 to 95 chebby or GMC to yank out the swirl port turd and Olds 350 power it. I will never run a circulating block heater, burnt my 94 Z71 to the ground. Remember we have -40C for weeks on end, a good block heater is necessary. But finding one that is not rotted and or overpriced is tough. A 3/4 ton with a 4L80E would ideal other than the ride and a weight penalty. At least no garbage 4L65-70E and weak aluminum front diff like the 1/2 tons. One more GM vehicle liberated from its chebby turd. Kind of like a manual disenpaction, pull that **** out😉.

I have one of those. "A 3/4 ton with a 4L80E" and it has zero rust, virgin truck and it could be bought.
I agree good grief. Went from racing to tow vehicle. 😂 Well I guess I will say I am going racing this weekend with my 442. Put numbers matching factory 455 back in after it's long rest. I freshened it up. Guess I will see how it runs.

I installed the engine in the car a few months ago as I did not want it on an engine stand going to waste. Waiting on a couple of rear frame braces, custom moly driveshaft. I`ll have to address a new hood so I can install the spacer and correct carb as what it made the most power with. The car is a complete monster at ANY SPEED. My speedo goes to 160 ( custom made) and will hit 140 very quick. I got out of it as The car doesn`t have a bar in it yet. Hopefully will be able to get some ET`s later this year as I want it to be straight. And before you ask...…..YES....it has my 2004R that has a billion passes on it with AC.
Thank you for all the compliments, I really appreciate it.

Dan...........have you raced your 403 Olds build yet, if so can you post time slips?
