427 too big???
is an all aluminum 427 sb be too much for the TPI system. even if i were to port it to perfection, could it still feed enough air or would i have to go with something better?

It will make a ton of horsepower and torque, but at a max of 4500 rpms, I would bet. TPI works with a 350 and is less effective with larger cubic inches.
