Tony what cam are you going to run? Also, make sure the builder uses the correct reluctor wheel, and cam wheel combo. Also make sure you get the cam sensor extension because on the LS3 the sensor is all the way in the front. Don't take it for granted that the builder and installer knows these things, because it will bite you in the *** when you go to start it... It will run, but start up will take a few tries and there will be backfiring while you are trying to start it.

The cam we are running is the same cam that came out of it. It's the Futral Motorsports F-16 cam with 1.8 rockers. That cam is a great cam for a track car. It seems to work out real well when input into the software that we used to design the engine with the bore/stroke/rod lengths of the new engine. So we're not changing it.
I really want to change to the later trigger wheel and computer but I just don't have it in me to screw with the wiring right now. But for sure, if I keep a LSx engine in the car, I'll be going much bigger in displacement (well over 500cu.") and at that time I'll go to the later PCM and drive by wire setup. And yes... I've been in discussions about the larger engine well before this last engine screwed up.

52mm inlet / 40mm ex. Quite a bit bigger inlet than anything on a 951 head.

Its amazing how much lighter modern small block stuff is compared to the porsche pieces.
