Ordered the Gears, Bearings, shims, and everything else today!
Now I have to get the truck outta storage. I'm scheduled for Mid-April installation. MAN this thing is going to be awesome!!!
Gotta send the Chip to Sal to have it calibrated.
New Mods this year:
Bassani Headers
Hi-Flow Catalytic Convertors
4.10 gears
New Chip reburn.
I'm thinking I'll drop .3 - .4 in the 1/4. Only reason I say that is because my 60' times SUCKED. I had 3.55 gears with 28" slicks. I don't think I had enough Ommph to get off the line. My best 60' was 1.84. I think I can whittle that downa little.
Plus I am running a conservative street program ONLY. No race tune!
