Another fine job by LMR! I let them tear into my car and put their touch of magic in it. The results? 454 rwhp 428 rwtq! The car feels like a beast now. I've been smiling all weekend driving it around. Haha We are expecting to squeeze a little more out of it when I get better long tube headers and loose the stock catback. Thanks guys, I couldn't be any more happy with it!

F.A.S.T. 90mm Intake Manifold
1.7 Yella Terra Rocker Arms
Nick Williams 90mm Throttle Body

SVO 42 lb. Fuel Injectors

once I change the Longtubes from 1-3/4" to some 1-7/8" and get an aftermarket cat back I hope to hit 470-475 rwhp. My exhaust is holding me back right now. I still have the stock SLP muffler.

I agree that the exhaust is probably holding you back. I have seen several Heads Cam Cars with the TFS 215 heads make 500 RWHP on a 346

Mark, glad you are happy with the car, thats all that matters. Dont let the one hater on here make you feel bad, that is some great power through 1 3/4 SLP headers and stock muffler. Car is a total sleeper!!
