I want to build a 383 stroker engine for my 84 firebird. I want to build a street/strip engine with about 425-450 HP and TQ range. I have made a TOPEND parts list that i think will achieve the power i want with the budget i currently have.

For the build I choose:

Patriot Performance GM Vortec 185cc Cylinder Heads

http://www.jegs.com/i/Patriot-Perfor...ductId=1192214

This seems like a really good deal to me for a set of complete cylinder heads vs buying stock vortec heads and having them all machined and buying stiffer springs and all the other stuff .Has anybody ever used this cylinder head or heard any reviews on it.

Comp Cams 'Xtreme Energy' Hydraulic Flat Tappet Camshafts

Operating Range: 2300-6500 RPM

Duration @ .050'' Lift: 240° Intake / 246° Exhaust
Valve Lift w/1.5 Rockers: .507'' Intake / .510'' Exhaust

I will eventualy end up makeing my 350 into a 383 stroker with this top end. I think i covered just about everything I wanted to. If any of you have used these products let me now how they are I would greatly appreciate it. Also tell me about your killer street/stip combos and if you think this is a good combo or not or what you would change.

Sounds good, get a 3000 stall, that way it will stall to 2500 foot braking. Ought to be close to 500 HP.

Good luck with it. I find that the more money i make, the more i want to spend that i dont have....never happy. The big block swap is killing me.

Do NOT get either of these products. Yes the Pro Products intake flows about as good as the Edelbrock but its a cheap casting knock off and I personally would not recommend it.

However what ever you do STAY AWAY from Proform rockers. They have a major design flaw and have been known to completely come apart in even mild set ups. Go with comp or harland for your rocker needs.

thanks for letting me know about these products.

I agree on the rockers. However, the professional products intakes are great. No one has any issues with them and they are solid. So, get the damn intake and save some cash.

should i go with a single plane intake such as the hurricane intake

iTrader: (14)

No. Stick with a dual plane.

The RPM air gap knock off is the best money can buy. Dual plane and it will rev to 7000 if it has to. But it keeps the bottom end TQ a street car needs.

I dont plan on taking this motor over 6500 rpms

ZONES89RS

Yea, the knock off air gap is just able to do it, it is great for low end TQ.

i use to be into 4.6L mustangs and thats where i first tried one of professional products knock off pieces. There is a reason it's called a knock off and not the real thing. Spend a little more and get the Eld the quality is so much better.

Yea, and several people are telling other to quit bitching and do some port work and it is fine.

**** happens, and FYI, here is a god damn almighty elelbrock intake that is NAME brand we put on my buddys malibu with a LSx. So for the bitching about "buy american", there it is. Your post is not such a valid statement.:

Sounds like someones getting a little butt hurt. I never said to buy american, i just said this particular company blows IMO. I don't thinking anyones bitching, except maybe you.

I don't really care where the parts I buy are made, I just try to buy quality parts, and as far as I can tell, Porfessional Products products don't seem to be good quality. I bet you could find 10x the complaints from people bitching about PP as you could Edelbrock or Weiand.

ZONES89RS

iTrader: (2)

Nope, not in my feelings. My PP intake is fine, no problem at all and is a great casting. So i have no complaint, the people YOU posted are bitching. They said buy american, so like i said, look at the post where the almighty eldeljunk is cracked around the ports.

I like them, but the fact is that they are a direct knock off of a edelbrock casting. 95% anyway.
