.557" purple shaft 318?

Streetable is any car that can drive further than a 1/4 mile! Duhhh!!...I have decided its safer to ram ( less risk of being unhappy) the .528" in at the moment with the std bore donk and see how close to 375+hp it might make.... and install the .557" in another block ( i have 6 318s) that is bored .040" with the KB399 pistons and H-beams and then we can spin the ***** up with High comp and a Super Victor intake or tunnel ram and run that motor HARD or throw it on the bottle if it can't pull the skin off a rice custard!!!
and yes old profiles for old motors by people who know better MOPAR ALL THE WAY!!!!!!!!!!! MOPAR! MOPAR! MOPAR!
