I just picked up a truck 409 cast# 3788068 and I have a Kohl 871 blower with Crower injection that I want to run on this build. I just want a reliable street engine maybe 5 to 7 lbs of boost. I plan on getting new pistons but Im not sure if the original crank and rods will be good to go. The heads are 333s will these work on a blown street application?? If anyone can help Thanks. I also still need to find a blower manifold that fits 409.
