The wife has agreed to let me build my new engine as long as I don't get a motorcycle so I have some questions. Right now I have a 302 in my 67 coupe, the headers sit low as it is, if I put a 351 or a larger engine what kind of problems am I going to run into as far as engine compartment space? When I re-built the car I had the engine compartment sprayed to match the rest of the car and I'm just worried about what is going to need to be moved/chopped/destroyed, to make the engine fit. Thanks for any help.
