Rick,
I'm going to try the iron block because I'd like to see how much HP there is to be gained vs. the aluminum. The iron blocks are generally more stable at temp and should maintain better ring seal. Ever notice that all the NHRA Pro Stock engines utilize an iron block. Granted the can afford the extra nose weight.

The class that I race in is based on a lbs. per ci. formula so that somewhat dictatates the engine size that I use. If I build a bigger engine I'd have to add weight. I'd actually prefer to go the other way and build a 421 ci engine and take more weight out. I may end up doing that with the Shelby engine and try the iron one at 434. I have enough parts to build a complete second engine already so if the iron block does'nt work out I can always reblock it with a Shelby.

As far as the Genesis block goes the current version looks pretty good. I met them at the PRI show in Indy last year and they've made a lot of design changes since the first generation. Genesis is actually hooked up with a Kryogenics company and we talked about doing some testing with them. We may do some testing with their aluminum block next year as well.

You are correct that I do already have a proven combo and don't want to get lost out in left field trying new stuff at my expense. They say that they want to "work with me" so we'll see how it works out.

Thanks for the compliment on the engine. It took a lot of work to get to this point and I'm actually into it for closer to $50k from carbs to pan. FE's that will live at 9500 rpm aren't cheap but they sure are fun! Have a good holiday.
