Can somone help me out with some ?s.My 56 has a camaro clip with a big block,approx 500 hp (not ran yet) theres really no room for a fan behind radiator,is ok to use a pusher fan and what size a/c cond should i use or does it matter.If the psher fan is running all the time shouldnt that be ok.This is the first time building a truck like this and want it right.

pushers work fine. see if you can fit two on there, or if not, use one big high flowing unit like a mark V fan. you can set it to turn on with a temp switch.

i run dual flex-a-lite 16 pushers on my 500 hp ford lightning, and the a/c blows nice and cold, and the truck doesn't overheat in traffic at 100*F outside.
