Ok, i'm confused again. the motor i'm building up is street/strip

Trick Flow makes big port 67cc heads w/ 215 cc intake runners, thats pretty big. Now wouldn't this rob alot of low end torque away but gain high end hp? The cam i'm using has a .507 intake and .510 exhaust lift so its pretty agressive. Its best at 2300-6500 rpm.

I'm guessing that for a street/strip i'm gona want most of my power at around 3500-4000 rpm.

If got these big port heads am i gona have really week low end power? Cuz u know i wana get pinned back when i hit the gas

should i just stick to the normal TF 195 CC intake runners.

Those heads?

It depends upon how much power you wanna make and where. 215cc heads are not too big depending upon the power level, but yes they will have less low end torque.

Thoes look pretty much like em, but the ones in summit are actually 67 cc chambers.

I talked to my friend earlier and he said that thoes intake runners might be too big for the Air Gap RPM, i'm not sure what the air gap ones are excatly tho. He said i should stick with the 195 cc heads and get a carb spacer which basically increases the runner length so i get the best of both worlds, maintinging low end torque and raising high end hp

 

My buddy has a mild 350

dart 180 iron unported heads
Performer RPM intake (non air gap)
mild solid flat tappet
10:1
Holley double pumper

Car goes 11.60s on motor in a 3400lb thirdgen

10.80 on a 150 shot

 

Maybe AES motors just fly.

 

appartently , hopefully mine does too
