I'm intrigued as to why he using the 7 liter Chevy (wasn't it originally the ZR1 mill?) instead of the FGT motor. I would think the FGT TT motor would hold up to the abuse a lot better and hasn't been plagued by the cooling issues I've read about on the twin turbo Vette motor run by Lingelfelter and others. Is the Ford GT mill too heavy or wide for the application?
