Thanks for all the positive comments guys, its been a long road and I am glad its finally running. However there are some minor bugs to work out of here. For one, I have a lot of fine tuning to do, its running and its running OK at best nowhere near 100% yet. I have some low speed drivbability issues to work out and of course top end needs to be finalized as well.
During initial break in runs, the engine make 600 ft/lbs of torque at 3200 RPM, it made 600 hp at 4800 RPM, all of that with just 7 degrees of total timing. I consulted with LPE and 21st Century Muscle cars about what they did on their test mules. LPEs engineer who worked on their project and was also one of the lead engineers during the Corvette LT5 developement program with GM, he told me that they ran 20 to 22 degrees of timing for max power! I don't think I will run quite that much, as they have 93 octane available to them there. At 18 degrees here that is nearly 3x what I am running now, its definitely going to come ALIVE to say the least!
