depends on what you want and if you can do the engine rebuild, i know its been mentioned already not to use a rover v8 but they are not much heavier than a pinto, cheap to buy and are easy to get 230 to 250bhp out of them and not alot of dosh to get there, decent set of heads, 1 1/2" headers, edelbrock inlet , and edelbrock 500 carb and 9:75 pistons and some other goodies it would be close to 250 bhp, and yes you,ve guessed it i prefer v8s
