I have decided on getting a 3rd gen F-body and using it as a 'recreational vehicle'. I know a couple of instances where i can get one real cheap, (bad motor blah blah blah). Theres also a little company called MARK's PERFECT ENGINES (or some other dudes name) that seels a crate 350, rated at 435hp for about 2500$. The thing is, say I start with a 305f-body... what rear end mods would i need to do in order to pull it off/ and will the stock radiator be enough to cool it sufficiently, seing especially sinces its bored over (but only 30 over)?
