Heck, anything will fit if you want it in there bad enough and are willing to do a bit of extra work beyond the bolt ons!!!! I do know the 455 Olds engine will fit in a '58 chebbie pickup!!! As Mike said, the A/C is going to give you some problems, without looking at the car, maybe a low mount compressor vs. the stock mounting location??? Headers, might as well plan on building some doubt seriously if anybody makes anything for it. But hey, if you want it in there, you can make it work with a bit of engineering and some good old fashioned physical labor!!!
