Thanks. So far, it is running 383rwhp and 312rwtq at 8psi with a 3.5 pulley. Have a 3.1 pulley 11-12psi that is going on, and shooting for 400-420rwhp. That is going to be as far as I go with the cast stock bottom end.

I'm thinking about getting one of these. insted of a two vavle Tbird.

It looks and sounds good.It's nice to see another blown mark VIII.

GD how much power did that make?? The 4v sounds so awsome winding up high.
