The camero is an awful donor, 1 the engine is in the wrong place, 2 firewalls too high, 3 shock tower is way too high and will need to be trimmed down or cut out completely. Moving the windshield forward doesn't change a thing. By the time your done making all these changes you'll be spending a ton of cash plus its going to end up looking very bad. Prime example is the Pontiac solstice murcielago build.
I for one rather build a chassis to fit the body not a body to fit the chassis. Once you start building a body to fit a certain chassis you loose alot of the former shape of the car that you are trying to replicate. You think that to yourself, oh i'll just cut a little bit here a little bit there, stretch this panel out, push this part in, make this wider, trim this smaller, by the time your done making all those changes it just ends up looking retarded. If you don't have money to begin with, don't even try bother getting into this type of hobby, I say hobby because you'll spend more money putting in to the build than making a profit from it.
