| Re: cheap power improvements to the 425... does a 472/500 really use that more gas then a 425?
since i gave up the idea of building up a nice 500 for my '79... I would like to keep the origanal engine, that way I can say "yeah, it has the origanal 425" and i am doing basic and simple mods so far... it seems like with a little wor, these can be opened up pretty nice....
how dificult is it to put a performance cam in the 425? |
