This will be my olds 350 setup

[1973oldsomega]

Ok here we go this is everything i will be using for my olds 350 engine. Let me know what you guys think.

-Standard bore 73 olds 350 engine.
-Speedpro flat top pistons with no valve reliefs standard size 4.057.
-melling high volume oil pump with a morosso pickup that bolts on.
-morosso 7 qt oil pan.
-Harland sharp aluminum roller rockers with a 1.6 ratio
-Comp cams double roller timing chain and gear set
-Gonna use a electric fuel pump.
-Oh yeah ive had all the machine shop work done on the engine but i have to take my rotating assy up there to get it balanced once i get my piston rings and the money to do that.
-I dont know exactly what carb im gonna use mabye someone can help me with this issue and lead me in the right direction.
-TH350 trans with a shift kit also gonna be running a B&M holeshot torque converter 3000.
the rear end will be a 3.73 ring and pinion set up with a power trax posi rearend.

Well there you have it, let me know what you guys think. Will i have some pretty serious power with this setup or what?

Thanks...

Compression ratio will be 9.1-9.4 depending on the piston to head, might be a tad too much cam. That is 224/234 @.050, right?

[Bobsw32]

Nice combination


I am ssuming you know you need to mill the heads as they are large (77cc) combustion chamber .......So you can mill them to your desired combustion ratio and that you have to port the intake manifold to match the heads as that manifold comes stock with small block ports

[380 Racer]

Everything looks good. Personally I would get a better cam from an Olds Vendor and up the compression a bit as stated. I would use a 750 cfm carb. I prefer a Holley but a Q-jet will work good too. Have fun

[cutlassefi]

I agree with 380 racer. Get a cam that's not so lazy. Doesn't have to be from an "Olds" vendor though. Don't get caught up in the Mondello/Engle scam. They aren't any different than any of their other grinds for a Chevy, Ford or whatever. There are a bunch of other cam companies that will work just fine.

Yes you are right about 224/234 @ .050, you think its a bit too much cam and others are saying not enough cam. I went with all the performer rpm parts because they are dyno matched for peak performance from edelbrock. Also ill be using hooker supercomp headers with magnaflow true X 2.5in dual exhaust. Thanks.

Yeah i know they are 77cc chambers. I just havnt made up my mind if i want to get them milled down or not. 9.1 comp isnt too bad but 10.1 or even 10.5 to one would be better. Where is the line when you cant run on pump gas anymore what comp ratio is that?

IMO, they are not saying MORE cam, they are saying a DIFFERENT cam. Those generic cams open and close very slowly. This tends to keep cylinder pressure down in low compression engines. Couple that with the larger port volume in those BB heads, and it has the potential to be lazy down low. A cam with a steeper ramps might be a better choice. I like Engle cams better than Mark but there certainly are plenty of choices. Call Tim at Bullet for some very practical advice.

It all depends on the combination. Cam, where it is installed, timing curve, quench, chamber design, and A/F mixture are just a few factors. IMO, if you are not very experienced at tuning, keep it right at 10 to 1 with those heads.

What are you looking for out of this thing?

A Nice street machine that i can drive to car shows and when i get ON it, it will fricken move and move fast

I agree with CaptJim on most everything except as he said, the opinion of Engle cams. I had one, didn't spec out as described and overall I wasn't impressed. My opinion. Also as Jim said, shoot for 10:1. Aluminum heads are a bit more forgiving.
Jim's right though, not too much cam, just consider a different one. Lunati makes some nice Flat tappet designs as well as others. Take your time. It's easier to replace a manifold if it isn't right, it's a lot more of a hassle to change the cam.
Don't forget to degree it as well. Jim has a good video explaining this.

Thanks for the all advice guys. Ok so i already got the edelbrock performer rpm camshaft and installed it but never ran the car. Would i still be able to send it back to summit for a different camshaft or no?

[1973oldsomega]

Ok change to the plans guys. I called up Rocket Racing Performance and talked to one of the specialist one the phone and they told me the performer cam i was going to use was not going to put out to HP i want. So i will be using the Top End kit from Rocket Racing along with a cam specially made for my engine i think it was somewhere around a .512 intake and a .528 exhaust i dont remember what he said exactly he was talking pretty quick and i was getting lol. So scratch the whole edelbrock performer rpm set up i was going to use and i will now be using performance parts from a company that specialized in nothing but olds they said i should be sitting at least 450 HP with my set up which makes me a happy man.

[captjim]

Are you going to be using the RR heads and intake combo?

[1973oldsomega]

Absolutely i am fired up about this now that i have talked to the experts on the subject. I feel more comfortable dealing with OLDS specialist they really know what they are doing. Also they are gonna be able to shave the heads down from 75cc to make a 10 to 1 compression. Everything else is going to stay the same but im scratching the Edelbrock performer rpm setup i was going to use. I will be using RR for my whole top end. Now should i still use the 750cfm carb. The track here in AZ is like 3275 elevation i know that has something to do with the carb setup right.

I would let the experts at RR help you choose all of your components, carb, ignition, etc.

[J-(Chicago)]

...



From stock #8's to RR's, in a single phone call. That's what I call an upgrade LOL.

Yeah that is what im going to do. What do you guys think of the setup now???

Yes its gonna be very nice from what RR is telling me

[380 Racer]

I have the RR setup on my high 9 second DX build and like it.

[1973oldsomega]

Are you running high 9's on all motor?

[380 Racer]

Yes.......9.94 @ 132 miles per hour

[1973oldsomega]

Ok so here are the specs of the new cam from RR. 286-276 duration, 227-233 lift @ .50 and .510 intake and .522 exhaust. Sounds better then the rpm cam huh. This is what RR recommended i use.......oh yeah 110 lobe sep

[cutlassefi]

Just out of curiosity, I'm wondering why such low lift for that duration. Did RR say why?

[captjim]

It sounds like he is going to use the 60803 Voodoo cam by Lunati. John at RR recommended it for me, too. Runs good, no real tuning or ET yet. I have it in my 10.4 to 1 355. 268/276 gross, 227/233 at .050 with .510/.522 lift on a 110. I installed mine at 104, IO at 9.5 before and closes at 37.5 after.

[1973oldsomega]

I told him what gears i was going to be running and what stall the b&m converter was going to be (2400) and that is the cam he recommended so i didn't ask any questions. One thing i will have them do with the heads when i make the order is mill them down so i have a higher compression. With the heads having 75cc CC's he told me i would be around 9.5 to 1 comp and around 450hp i want the engine to be around 10.5 to 1 so i will have them milled down so i have that comp.

[380 Racer]

Yes Mark, I was thinking in the .550" range. I also like a 108 LS. But then again I'm no expert by any means.

Nick, you certainly are no expert, all you have is a single digit ET running a SBO in a full metal car. You really have no business even posting, you should just sit back and read, learn a little bit before you start running off at the mouth.

Seriously, though, the 20-22 Engle has .496/.502 IIRC and 226/230 @ .050
So, the Voodoo has more lift with similar duration, and the ramps are very fast so it "acts" smaller, IMO. Mine has plenty of vacuum and a very mild sounding idle.

[cutlassefi]

Sounds like a nice build Omega! It's hard to get more lift out of those ramps cuz they're so aggressive. I'll be doing something similar, except I'm keeping mine more blower friendly. 9.8/1 comp, 4.155x3.400 bore and stroke, Edelbrock heads and an Erson Hyd Roller, 226/234 @ .050., on a 112, .627 lift with 1.72 rockers. I personally like as much lift as possible. It will typically give you more hp everywhere.

I would think yours should make a solid 450hp, maybe a bit more as the RR heads seem to flow a bit more than the Edels. Keep us posted as you go. Are you going to dyno it?

[380 Racer]

Thanks Jim!, but I'm still learning every day

[BIGJERR]

Rocket Racing are good guys..........As with any vendor there will be some ups and downs but over all I would say RR are top notch!

Yes im going to dyno it and a shop here in Tucson once i get it complete and running that way i know its completely tuned right by professionals.

[1973oldsomega]

ok so i changed it up again. He was giving me advice thinking i already had a 2400 converter so i asked RR if i went with the 3000 converter could i go with a bigger cam. The 60804 lunati cam kit.

• Advertised Duration (Int/Exh): 276/284
• Duration @ .050 (Int/Exh): 233/241
• Gross Valve Lift (Int/Exh): .522/.539
• LSA/ICL: 110/106
• Valve Lash (Int/Exh): Hyd/Hyd
• RPM Range: 2000-6000
• Includes: Cam Kit

this set up looks better and will have more power. gonna try and be around 10.5 to 1 compression and 500hp out of this build that is my goals

[380 Racer]

I personally like that one better, but I'm more race orientated. Next time you talk to John......tell him Nick says hi.

[captjim]

John recommended that 60804 for me, too, but I wimped out and went with the 60803. I only had a 3.42 gear and wanted all the throttle response I could get.

Lol i will do that. Is John the only tech guy there he seems to be the one i talk to every time.

Ill be running a b&m holeshot 3000 and 3.73 gears so this will be a good set up for me. I should have some pretty stout throttle response. From the description the cam is supposed to be a pretty aggressive sounding cam at idle.

Iam running a 3.73 gear.......Should be a good street gear and have enough umph to get the car going nicley!

I cannot wait to get this engine together. Ill have to wait till i get back from my Afghanistan deployment to buy my head and intake from RR oh i can wait to hear the engine run... The rotating assy is at the engine shop right now.

[Warhead]

Remember, more compression = more power.
As AHNOLD says, do not be afraid to pump it up.
Can you get 11:1???
Ya.
