One engine you might consider is the 3 liter Chevy engines that Mercruiser, Volvo Penta, and OMC have been using for years in boats. They are super little engines, I think of 181 cubic inch displacement, and a machine shop guy told me circle track racers use these with I think 327 pistons and some head work, and crank out good numbers.

I bought one for $ 200 for just such a project as you are doing, but finally got tired of it laying around, so I put it on Ebay and sold it. Nice part is, it has a regular Chevy bellhousing bolt pattern, and I understand 6 cylinder Chevy flexplates and things go right on it.

I didn't research it really deeply, but I planned on yanking off the watercooled exhaust/intake manifold and fabbing up a tube intake and exhaust setup.

These are all over the place, and pretty cheap too. Being that you live here in Florida, you know how many boats we have here.
