I talked with Brian Tooley Racing about my goals with a cam, what racing I'm doing and my modifications. They made a custom grind based on those items. I highly recommend just chatting with a shop like them or similar.

3.73 vs 3.9 final drive? Where is the best place to find a used 3.73? Any auto guys with a 3.9 want to trade for a 4.56? Is everyone with an LS3 keeping the redline 6600 RPM or is it safe to push it a little like 6800-6900 RPM? I am looking for 72 to 73 mph at the top of 2nd gear. Using this calculator http://www.apexgarage.com/tech/gear_ratios.shtml I came up with the 3.73 would be best with the 6600 redline but 3.9 would work for me with a slightly raised redline like 6800 RPM.

I like 3.55 but 3.73 is pretty good. I have my rev limiter set to 6500, I know lots of guys spin to 7000 without problems.

This is a nice calculator

I'm on the factory rear end (4.10) currently (temporarily while searching for an m85 IS300 rear end). First gear is flat out useless. I drive from second gear for everything. I'd recommend between 3.55 to 3.73 for sure.

I drove the factory 4.10 for a few months and honestly driving the car around was a bit miserable. I was able to get a good local deal on a 3.73 and it's a totally different car. A pleasure to drive. Very easy to drive on any gear, usable gearing now. Honestly one of the best mods I've done on the car.

If I'm determined to have AC and dry sump so my engine doesn't blow first day at Laguna is an LS7 my only option?

GrabTheWheel · 10-29-2018, 02:15 AM

Maybe accusump plus a baffled oil pan will be good enough?
