hey guys im needing suggestions as to if it is even possible to do this: My buddy has a 1980 crew cab 350/465/205 60/14b with 4.56 gears and some metric 32" tires, He mainly uses this to tow his 28' camp trailer and his utility trailer. his current motor is getting tired and has problems pulling grades above 50mph and he complains of no power in 4th. I gave him a 350 out of a 76' that i junked, it runs, but has low oil pressure-5psi when warm 25 when cold and it smokes a bit, he is wanting to rebuild it. is it posible to do this with $1000? if so what combos should we look at? i told him to spend the $1400.00 to get the 290hp gm crate, but he thinks he can build a better motor with more hp for that price? Is it doable or is he drinking his bathwater?
