Its a good running motor i paid 900 dollars for it the transmission and truck. Im wondering if i got a good deal? what can all be done performance wise to this motor to give it more power?.
The 4U casting number on the crankshaft denotes a 429, the D0VE block makes it a 1970 or 1971 model. However the D3VE heads would not be original on such an engine and would come from a 1973-1985 460 or a 1973 429. It's as if the 1970-1971 D0VE heads were swapped out for 1973 heads.

If you are mistaken and the block is actually a D1VE (not D0VE), then it is more than likely a 1973 429....a complete turd as delivered from the factory but has the potential to be a lot more.
