The difference between an iron and an arruminum motor is not $10k...in fact it's not even $5k when you figure in some machining and sleeving on an iron block. It's real easy to spend $25k on an iron block. It has more to do with all of the other "stuff" that goes into and around the block.
Sit down with George and some of these other guys and talk about what you want to be able to do with car. Horseys are nice, but look at torque, driveability, cooling, etc. For example, Fresno (my town) is extremely hot in the summer so I needed something that would run cool. Arruminum helps in that regard, and my builder (who lives here in Fresno) set it up that way. I've taken mine in stop and go in 110 degree heat and never had it go above 190. All the horsepower and torque in the world is useless if I'm sitting by the side of the road with a steaming motor...makes Cobras look bad too.
Autocross? Low end torque. Open track...different attitude again. Do you want traditional for looks, or do you like the shiney stuff and the ability to spec race over a beer?
Look deep into yourself and the truth will make itself known to you.
Damn! I'm gonna write that one down somewhere.
And have fun!
