no the tpi wont flow the air the 400 needs,they run out of flow on a 350 around 5000/5500.i tried one on a 400 and it flattened out around 4100

i would use the 750/800 q jet the 400 loves them

If you really want to go efi use a Holley stealth ram intake. THey are the best intake for 23 degree efi heads.

the one from the gm ramjet 350 works pretty good as long as you dont need emission testing, it has no egr provissions

The Camaros didn't have the TPI until '85. Maybe you have a TBI? Wanna get rid of it?
