This will be my olds 350 setup
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 and my rotating assy is balanced and the pistons and crank are now installed
-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 3.91 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...

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

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

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.

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.

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?

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.

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.

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

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.

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.

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.

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?

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.

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.

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.
