it might help to know why you are doing it ...


.

Im thinking about doing it because, the engine is old and things keep going wrong with it left and right. i want to get a 454 long block and totally gut it out and redue the whole thing with the parts i want. i want it to have some power and be reliable and also run smooth.

Im sure it would be possible. But if it were me I would redo the 472. That engine is 375 hp stock. With minor mods you could get good power from it yet still run nice. But just an opinion. I have a 70 coupe deville and thats my plan.

I havent baught anything for it yet. Just want to get some opinions before i make a purchase that im going to regret!
