: I have a 454 gen V crate motor from GM. The motor has
: TBI or peanut port heads. I am having a tough time
: finding a intake manifold to fit! Weiand makes one
: that should fit, ha ha I sent it back. The intake ports
: could have been made better with a hand drill and a
: 1/2" bit. I am using a oval port intake now. The
: local GM parts person says that the oval port and the
: TBI/peanut port intakes use the same gasket? Should I
: look for a stock TBI intake? Is there someone who makes
: an aftermarket one? Should I change the heads to oval
: ports? How much am I hurting performance with current
: set up?
Sorry you won't find a intake with the small ports.
They used the large oval port intake on the carb.models and the TBI models. WHY ? Its suppose to cause some air turbulence which makes a better air&fuel mixture . It doesn't hurt low end torque .If your looking for more power buy Eelbrock #6047 heads they seem to work real good.
