Building a nice street car.

Rumble, I don't know if coating the chambers would be enough to keep it out of detonation. Id rather just run the good gas and be safe. These pistons have had a lot of extra weight removed and may not hold up to any detonation at all.

For tires I'm going with a M/T drag radial do it will most likely be a 235-60-15 so 26" tall.

The cam I'm thinking of is a a solid version of the extreme series its around 240 intake 250 exhaust.
