I would have to put the potential at around 600 hp to stay reliable. I like
the Idea of a turbo setup, I've considered doing it for a while now (empty
bottles suck). The programable FI sounds like a good Idea while expensive at
first it allows for large changes with just minimal effort a the track, I'v
seen guys drop a full second off their times just changing fuel and timing
curves over the course of the day. I would call mopar and see if the can
prep you a 360 assembly with forged internals. It would probably end up
cheaper than buying two cranks two sets of rods two sets of.................
I'll let you know if I get the turbo idea rolling
