It made over 600rwhp thru an automatic with a Sullivan and GT heads. With GT heads, mild cams and a Cobra R intake it could be a mid 500rwhp, very streetable and formidable combo.

N/A?

Im thinking about just hanging some navi heads with a sullivan on it and letting it eat.

It would be a beast and not come with the additional weight of a a cast iron block would. 500rwhp would be easy to get with navi heads and a Sullivan.
