whick upper and lower intake should i get. i got 30 pound injectors 6psi blower stock heads crane cam rocker arms 1.7. i was thinking about the Trick Flow EFI Street Burner, Edelbrock Performer, or the Mustang Typhoon. which is the best performance intake and which is best for my setup. also what size throttle body do i have to get to go along with everything. please help

70Mm TB and 73 to 76MM MAF.
For the money, I would go Typhoon, though the Holley Systemax intake seems to be the best for power.

for efi , i had a rpm 2 and it worked well but is for a little bit more than stock too works like its suppose to.

RPM II. dont look at the typhoon unless you feel like doing some clean up/port work on it....then shes worth it.

i wouldnt go with the TF intake with that blows.


BTW did anyone read the summit built sn95 on 5.0 magazine september issue? 347 stroker w/ trick flow top end only hittin 311hp and 345tq!

I usually tell people to buy the Systemax intake, and others have argued about the RPM II. I actually looked at the RPM II the other day and started laughing. It's almost a dead nuts rip off of the Holley. LOL!

So I guess the answer is...Don't bother with the intakes you listed, get either the Systemax, or the RPM II.

Yep, and it was originally the Vortec intake.

For a 351 looking in to Trick Flow R series intakes.

anyway, I hear the systemax II is a good intake with long intake runners for more low end torque
