    If tuned properly, let's say 380 to the wheels. Post back. I'm interested to see.

    Eliminate the Slowmaster and it should pickup 40hp. When I took off my Super 40's one time at the track my car picked up .4 thenths, guess what happened to those mufflers?.

    Well tuned with a good oil pan set up, 425 at the wheels and 490 on the pump.

    Plans have changed going to do some head work and run a high lift roller cam on a 108 or 110 lobe separation. Builder told me it might net me another 40 to 50 hp and tq
