ohh I KNOW this. the pistons are hyperucraptic and the rods are bamboo. I know as I found out in 12000 miles that they no likee boost. :( the 96-98 motors will take a better workout than a mach or 99-01 cobra.

How much boost did you put into it? Which supercharger/turbo?

I've been thinking about boosting it but I might build the engine first.
