I was just looking through the november issue of four wheeler, at the TTC competitors' rigs...and there's a scrambler in there...and it says it has a ZZ502, with chevy TPI? and in the pic, it does look like a factory TPI plenum. does anyone know anything about this? is there a way to adapt TPI to a big block? I've been wondering about this for a while anyway...since there doesn't seem to be any "affordable" way to get MPFI, unless you're running a small block. I was just curious if anyone knows of a way to do this...or if it's really just another expensive aftermarket setup.
