New 5 speed from Tremec TKX

I will certainly reconsider that gearset. I remember 3.42 and lower gears were recommended with the 3.27 first gear. 11.60 overall 1st gear ratio with the 3.27, 10.188 with the 2.87.


IDK about that SLR being too steep. I’m at 14.1 and I’m going to 15.07 because 14 isn’t enough for a 3400 pound car IMO.

The SLR issue has been skewed because of the powerglide. Unless your car is 2900 pounds or under, even that 11.60 first gear sounds tall to me.

I’d call someone like Advanced Clutches in Idaho or Black Magic clutches or both and talk to them about SLR.

Car weight and SLR have a huge affect on clutches and clutch tuning. If the first gear is too tall, even driving the car around town is miserable, you have to feather the clutch all the time...just a PITA.

And one way guys bandaid that is with a 30 pound flywheel. If first gear is correct, you can use a 15 pound flywheel and the car will drive better everywhere.

Just my opinion.
