i just built a 350 for my pickup. installed it and timed it. it overheats.
pressurizes cooling system and overheats quickly. removed thermostat and it runs great, a little cool but runs great. installed new thermostat and overheats. am i missing something? i read somewhere that i could have put a latter model water pump and that could cause a problem with the reverse rotation. this is a bare non emesions motor. what is my deal.thanks cody
