Default Finally took a 25-70mph of new cam

It's alright for 3.42s stock 4L60e and 83lb 20" rims

Going up a slight incline and back seat was full of tools and old parts <<<< excuses hahaha

vinci 210/218 .584/.584 116lsa that lift is from 1.8 rockers
milled .03 862s around 9.8:1 compression

Lts, CAI, efans, UDP, P&P stock TB, duals with cut outs closed
custom tune hp tuners

The cam shaved a whole second of my 25-70 punch

God i hate stock converters. That horrible shift extension just kills it. Besides that, it seems to pull pretty good.

Only 14* of timing?! Fill up with 93 and throw 10 more at it and see how it feels!

Ya that needs more timing, 14 is pretty low.

I love the stock converter for grandpa daily driving but it sucks wot the damn thing drops down to like 3700rpms. makes the 60-70 slow getting back in the power band.

The transmission has almost 160K on it. I'm just going to have it built and replace the stall when she goes. 2600 perhaps I can't stand 3000+ stalls for dd and towing.

I was contemplating whether or not to run premium. I fill up twice a week and year round it's almost $600 more than 87.

I have been told by 2 tuners, a real split duration bleeds off so much cylinder pressure switching to premium wont make but 5-10hp difference.
