I already have the Max Moritz pistons, the larger Mahle cylinders and 964 cams. It might not happen soon but it will happen. Our shop built up a 3.4 with 300 rear wheel hp.

Those are some serious numbers, I am looking at 250 RWH.

My 3.4 liter engine has the Max Moritz pistons GE 80 cams, twin plug crank fired ignition and about 10.5 compression ratio. For reference it made 290 RWHP on the dyno with open exhaust but is probably down 30 or 40 HP with mufflers. Still a pretty exciting street ride. It will pull on my sons C-7 Grand Sport 2nd and 3rd gear and then he pulls away. He's got 460 HP but in 3200+ lbs car, mine weighs 2050 without me in it, so pretty good power to weight.

I'm running Weber 46's that have had the The Paul Abbott treatment at Performance Oriented. With open exhaust it needed 185 mains to max the HP. With mufflers I'm experimenting with 165 or 170 mains to get best drivability.
