i just want to build something to hold much more power than i'll be making to leave room for future mods (more nitrous, turbo) i see where u guys are going with the aftermarket availability of the windsor. but as far as the cleveland goes aside from distributor, exhaust, and oil pan, all i really need is the lower plenum to keep my fuel injection. Added bonus of the cleveland is its allready drilled for oil flow, its 150 buck and a 4 bolt main. i still love the ideal of a big inch windsor, but a bare set of ausie heads are around 400. i know i'm rambling but i guess what im saying is the aftermarket advantage of the windsor isn't really a big deal since i would need essentially the same parts for the windsor as the cleveland.
Sounds like you already have your mind made up.
You can convert a carb intake to fuelie, have holes drilled and weld in some injector bosses. Nothing new, been done before.
