Won't catch me driving around in any fiberglass misguided missle, mine at least has a little bit of metal in the body, lol
I would recommend the route that Brent has said to go, build the engine up first, with the venom kit and forged , dished pistons, stroke it to 4.2L maybe over sized valves, what ever you want, then if you want even more, go for an intercooled supercharger when the engine can take it. Then let me know which way you are going so I will know to get my GT out of the way, lol.
