Greetings and thanks in advance to anyone willing to offer any advice they can. For the record, I'm a beginner to car stuff in general. Anyway, on with the questions. I have a 57 Chevrolet Bel-Air, as mentioned in the title, and I was wondering first of all, is there a way to find out which engine is in there? All I know for sure is that it's a V8, and I'm told that the only three it would probably be would be either a 283, 305, or a 348. Is there any way to know for sure by looking at it? Second question, what are some hot rodding/customization options for 57's, and roughly what would they cost? First of all, what would an entirely new engine roughly around 400+ HP cost, just in advance, that would fit in it? Second, since I would prefer to just modify the engine that I have, what could I do to it and, how much would said things speed up the existing engine? Exhaust systems, carbuerators, whatever. Also, finally, what's a decent amount to pay for a good paintjob? Thanks for any help/suggestions!
