If I have to overhaul my 350 I'm planning on putting a different motor in for the summer while my 350 is getting overhauled. So, what is a stock 400 Pontiac motor out of a 68 Bonneville worth? The motor is stock 8:1 or 9:1 motor. The guy told me that the motor ran perfect before he upgraded to a 400 HO motor out of a Bird.
I just sold a perfect running 1968 400, 290 hp 2-bl carb motor for $400.00 yesterday, but it had a new water pump, all new gaskets including the rear main rope seal, wires, cap, plugs ready to install, even fresh paint. The guy was real happy with the deal, he's putting it in a 1968 lemans.
