Are there lower final drive ratios available for a 901 trans?... Yes, I said lower. (IMG:style_emoticons/default/biggrin.gif)

Wow. More input than I usually get on the tech questions. Thanks guys! I've been doing research and planning all day, and I think I have a plan now.
ArtechnikA, to answer your question, it's a T4. I'm planning my next engine to actually fit into a solo class, instead of just building whatever and seeing where I land. What I was trying to avoid was a rather ridiculous weight penalty formula based on displacement, and make up the HP difference with RPM. I think it's doable, and I'd love to be the one to do it, but given where I'm going with the car I've decided to stick with the slower turning 'stroker'. For autocross right now, I can either eat the weight penalty or reclass to XP, but the ultimate goal of that engine is to take me into GT-3 road racing. When the budget allows, the larger engine will be legal for that class as well. It's still no tractor with an 8500 RPM redline, but I can make the gearing work for that. Crunched a lot of numbers and read a lot of rules today and I've got a solid idea of what I'm doing now. Thanks guys. I'm saving this thread for reference.
