P&P questions

[Neale Flynn]

I was wanting to know how much a P&P job on the intake manifold of my 3.4 Firebird would cost and how much power would it add with an intake system and headers cat and catback?

Would get you maybe 1 or 2 hp. Not worth it unless you're doing heads/cam, turbo, etc.

[Neale Flynn]

what cam would you reccomend for that car and how much power would that give?

[98Camaro3.8]

I have no experience with the 3.4, so I don't have a clue. Best bet is to do a search and see what others say. I know I've seen it discussed recently.

well depends on if u wanna do FI or stay NA. There is really no point in doing the intake if you dont p&p your heads as well

a good NA cam is the GT2 cam
do a search and you'll find all the info you want

someone *cough*the 3.8L owner*cough* has obviously never loked at the inside of a 3.4L manifold where the injector sits. im not going to take a random guess at to how much power it would add without the heads being ported as well, but i will tell you its gonna be more than 2 HP if done properly

[Neale Flynn]

wait isn't the gt2 only for 3.8 engines? cuz i have a 3.4

the GT2 cam is for the 3.8L , maybe you should do some searching yourself

Yes, GT2 cam is for 3.8s.

You are correct in the fact that I've never looked inside the 3.4's manifold. I've never even seen a 3.4L for that matter. I would still be surprised, however, if you got very much hp from it with an otherwise stock motor. I could very well be mistaken. But either way, you're not gonna see 20hp. [img]tongue.gif[/img]

[StudlyCamaro]

i will agree that a ported manifold will not give 20 hp on a 3.4L

[phoenix64]

I didn't even port my manifolds, I just polished them, and I picked up a 7% gain in airflow. I beleive thats about 14hp.

Im only interseted in FI so i was just tring to give the guy some advice ;)

[Neale Flynn]

well ok im not gonna mess with that i guess

[NoRiceInside]

since i'm resourceful, i'm going to attempt to P&P, or at least port-match, my 3.4's heads. is this as simple as just buying the bits from summit, slappin em on the die grinder and slowly grinding away the cast iron?

[oil pan 4]

Not quite like that.
