427 LS7 with alot of tuning needed
Keep messing with it man, I had the 418 l92 stroker on the dyno the other day & it made 550rwhp before much tuning. I'm hoping to see you get near 600rwhp.

Thanks Jason, I will keep you guys posted. I am sure there is alot more hp in this thing. I am just hoping to get that torque number up into the 500's. Also, this thing seems to die off after 5800-6000 are you seeing this on all the L92 stuff?? I figured with the advance in the cam that it would have moved the power band up in the rpm's. Thanks again for the help.

I can crank her, turn the AC on and count to 10 and back out of the garage. NO problem!! It was worth the money to get it. Might not get more power but just driving around town is alot better! Just my .02 Good Luck!
beard, I agree 100%. Just a lil arguement a local tuner and myself has. He says that it is ignorance to take the MAF off a car and that any car will run better if the tuner is competent enough with the MAF on the car. Most the time the MAF is fine, but in a big cam/high reversion setup a SD tune will out drive the MAF car. Grimloc3's car is one that he tuned and was done with the MAF on it and it was supposed to be perfect in everyway and just far superior to a SD tune due to the highly technical calibration. Funny, Grimloc called me to help him get the car to idle! 
Hope the advice helped Cole! Good luck with it.

I have had several different combos ranging from 10 to 11:1 static compression, and I have never logged differences in MAF Air Hz just from the compression change... LS1 Tech Stories

The reason you see no change is you are playing with 10-11:1 motors. Im talking about 700+ flywheel N/A motors 
Yes, but the compression isn't what chops the idle and causes it to run like ****. It's the overlap in the cam that causes the bucking and surging. And for the record, it is much much easier to get good driveability out of an auto w/ stall than to do it with an M6.

Whether you go SD or MAF, the narrrowband O2 sensors have to come out and the car must be tuned in open loop. The stock O2's are too slow and will foul out alot.

I am using 02 ZO6 o2's if that makes any difference.
