The ad says the block is a D1VE and the heads are DVEA2A. I've tried to research casting numbers...If I have it right the head #'s are missing either a 2 or a 3 after the D. If I have it right these are the worst heads for a performance rebuild and aren't interceptor heads. Am I correct? Should I stay away from this engine? I dont race, but I dont want to swap out the Cleveland umless I can get 450hp or so out of a 429. Also, what is the weight difference between a stock 429 and a stock Cleveland?
I would think hard on what I want to do with the car. Do the 351C numbers match? It they do I would keep it. The engine can give you what you want. Plus you want have to modifiy your shock towers. The 429 is a nice engine, and it also is 32" Long and 26" High and 28 5/8" wide. Where the 351C is 27-1/2" Long and 20-3/4" High and 18-3/4 wide. With a little $$$ and some work you could have a nice street rod with matching #s
not to mention your hole front suspension will have to change.
