Well I have a quick question for you all, whats my engine worth. It is a 400 sbc. It's casting #'s are -3951511. It has world product heads, a decent cam and a weiand intake(7546), Holly carb(750), water pump, pulleys/balancer, flywheel and clutch, fuel pump alternator, valve covers, distributer. All is used, but in working order. However i took the engine out because i drove it too fast and it spun a bearing i think. So it will need a quick rebuild. I had this dynoed and it ran 260hp to the wheels, and 321tq.

ANY Ideas, Im not desperate to sell it, but for the right price. I have one person interested in it for parts.

Well if the spun bearing messed up a main journal the block is probably junk and worthless. The heads will have some value.
