Gears & Axles - What Final Gear Ratio
04-14-2012, 08:30 PM
Hi guys. Got a L92 motor and 6L80 transmission. This car will mainly be a street car with an occasionally trip to the track. I am looking for a combo of good gas milage and performance. Thinking of something in the 3.07 or 3.27 range depending of what rear end I put under it. I believe the 6L80 has a 4.05 first gear.

After doing some research I think I will go with the 3.27 ratio.

What car is this going in ?
Are you planing on keeping the vvt ? or converting

1965 Buick Skylark. I will keep the VVT and go with the Texas Speed VVT-3 camshaft. I have purchased the LS3 intake already complete with injectors and fuel rails. Heads will go to Dr J for valve job, milling and "blending". Hopefully that will net around 550hp at the flywheel. Going with 1 7/8" headers.
