I got the LS1 running today. It is still not running quite right but it starts every time. With the aluminum flywheel it revs very quickly, now to get it to idle better. There is still lots to do, but the list is getting shorter.
It will run alot better with the exhaust on it, needs backpressure for the oxygen sensors to work properly.
Started Dec 1/07 and on the road Sept /09.

Great job, like Russ I'm a purist, but I truly appreciate the uniqueness of your build and choices. You should post on the other forum so the guys over there can see also.

Understeer is when you hit the wall with the front of the car and oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall and torque is how far you take the wall with you.
Fire in the hole!
Nice Mike well done. How's the exhaust coming?
John it is not coming along at all. I am embarrassed to admit this, but I failed to research the rule book well enough. I was reading through the SCCA rules on another matter and re-read the XP exhaust rules which have no restrictions......except for the fine print that says to comply with the safety inspection. I jumped to that section and found the the exhaust has to exit behind the driver, or out the side. This ruined my whole day bigtime!!!!! So out came the saw and I am currently working on plan B and have figured out a plan C just in case.
Perry thanks for the advice. Russ and Hank I fully understand the true artwork you guys are capable of. Thanks for the cudos even though my build goes against the grain.
Any ideas what could be causing your Idle problem?
I've worked on a few LS1's with different cam/lifter/pushrod geometries, on the open loop tunes.... They can be problematic to say the least but are easily correctable by some general knowledge and a laptop tuning program.
If your issue exists in a mechanical manifestation, Vacuum would be First guess.
Great build, I really applaud you for going against the grain here. Good job!

It was close to the throttle body but is further away now. Now the idle is very high does not rev freely. I will get it on the dyno when I get back in town from vacation. The original problem was from a vacuum leak off of the port for the brake booster.
