Hello, I have a 350 that came out of a 1976 C-20 pickup. It has about 20,000 miles on it since it had .020 over pistons & rings and a crank kit with .010 over rod and main bearings. Motor ran very strong and dependable until I noticed a small leak around a head. I pulled them and the valve guides were worn bad. I replaced the heads with a good set, installed new cam bearings and cam, timing chain and gears and oil pump. I also trashed the oil pan and chrome front cover and replaced them both. It has new seals front and back and also has an electronic ignition distributor. It does not have 4 bolt mains. I have about $700 in it but will settle for $600 firm. Can start so you may hear it run. Selling as is. rdsky
if you still need this motor i have one for sell in my 1984 chevy suburban i;ve had it for five years and it runs very strong but i'm parting out my truck. if you need it.
