not sure if it blew up yet or not. Order new headgasket and rings. Using Arnells old SFP manifold and SC61. Putting in 3inch dp and catback with 00 itr cams. Hoping for 500 at around 20 psi. at 28 who knows. What's ricky's old setup? Even with drag radials traction is an issue. I was running better 1/8 miles at 9 psi than at 12 and 14. Just too much out the hole with that much boost.
