Have: K&N High FLow, Trans Kit, Dual SSEi exhaust with the factory tips on SE trim, SLE, SSEi struts.

Want: ZZP SS L36 supercahrger kit, New paint job ! Clear coat is liftinf on the trunk lid like most Bonnevilles do!

If you supercharge the L36, have tuning figured out before you install the kit. ZZP cant do anything for a tune for your car.
Also stay close to stock L67 boost levels because the 60e trans historically doesnt hold power as well as the 65. It wont matter what upgrades you do to the 60e.

Also, the SS kit is extremely overpriced. While it is easier to just swap in the LIM with the injector bungs, it is probably not worth the money they want over just swapping on some L67 heads.

The 4t60 has all 4t65-e internals with a 3.14 ratio instead of 2.84. My father set it all up a few months ago when the tranny went. So that's all set.

This post is not possible for more than a few reasons. But, I'll start with the easy one. A 3.14 ratio is not possible with any combination of 60-e or 65-e chain and differential ratios.

I'm probably the only one on this forum who actually ran a few 65 parts in a 60. I know what's possible.

So, like I said before, it won't matter what upgrades your dad did to the 60e. It's been proven to not hold up as well as a 65.

I'm telling you man he's not some side of the road mechanic hes had over 20 years of experience with GM overhauling these transmissions.

I'm telling you simple facts.

1. GM did not make a differential and chain/gear combo that nets a 3.14 FDR. It doesn't exist. Give it a try, multiply any of the ratios by the ratio of the differentials available.

Chain and gear ratios available:
1. 33:37/1.12:1 (underdriven)
2. 35:35/1:1 (direct drive)
3. 37:33/.89:1 (overdriven)
4. 38:32/.84:1 (overdriven)

Diff ratios available:
1. 2.84/2.86
2. 3.06/3.05
3. 3.33/3.29

2. With "all 4t65-e internals", you have a valve body that regulates line pressure via a pwm solenoid. You cannot control this with your PCM.

Feel free to post pictures of the build, details on what modifications to parts were necessary, etc. Without that, there's no reason to believe a 4t60-e with all 4t65-e internals exists. Especially with a FDR that isn't possible.
