Thanks everyone for your replies, Richie Z thanks for the sanderson headers tip. They are a bit pricey so I will wait to see what kind of clearance I get once the motor is in place. Anyone else out there running a big block chevy in a 55-57 truck I would really appreciate any advice or experiences good or bad with this set up. I was thinking about staying with the long water pump set up and try to move the radiator forward or just use a electric fan set up let me know what you think.
