Still some some tuning to do, but this thing runs well now. Timing can still go up a bit and I need to optimize the WOT AFR a bit. Anyways, other than that I need more stall for sure.

Looks like it runs pretty good. Just need some better gears now.

 

it's already got 4.10s

 

That 4L80e really extended all of your gears out a lot compared to a 60e. My 2nd shifting out at 6700 is like 85mph. You need 4.30+ gears

 

I wont be going any steeper on the gears. I'm turning the max # of rpm's cruising on the highway which I'd like at this time. Some 26" slicks at the track are going to make a world of difference...

 

Why more stall?

 

The cam shifted the powerband significantly up from the stock cam and it just feels like it would be better if I could get up higher in the powerband faster. The 10.5" 3600 was a perfect match for the stock cam.

This thing hits pretty freaking hard from a 70 roll with a 4-2 downshift though Got the tune all buttoned up, 12.5 AFR @ WOT, 25 degrees at peak torque working it's way up to 29 degrees up top. Prior to the cam EFI live was showing 390 flywheel HP, after the cam and tune it's showing 474 HP. I don't expect the #s to be at all accurate, but I think it is a good measure of the gains I got from the cam.

 

Is it running? I cant even hear it. Lol

 

good ole stock muffler Damn thing might be costing me upwards of 10 rwhp, but I love the fact that I can cruise on the highway with bone stock sound levels. I'll probably just end up welding in a cutout, but maybe something like a Corsa setup if I can get it at a good price.

 

Quick and quiet, very nice.
