Default Supercharge with GT40 Y heads?
Hello, is it safe to supercharge with the aluminum GT40 Y heads? I only want like 5-6 psi and am using the stock shortblock. It is a 89 so it has the factory forged pistons. Last, Paxton or Vortech? Thanks

Yeah it's alright to supercharge with aluminum headsas long as your compression ratio isn't too high. Paxton just got rid of the novi 1000 which would have been perfect for you. Look for a used novi 1000 kit.
