I had 3.73's in my 88 with a auto and everyone told me how the car would wake up and it did, but I really wished I went with 4.10's and will this time with my new project

and if you didn't put a trans cooler in the carfor the heat and you most likely have cut the transmission's life by 25-35%
I havent put one in yet but Im thinking about doing it in the spring. Just one of the generic parts store ones should be fine, right?

I use the plate type but using the tube type from HAYDEN#1405 will work great this is one of those bigger is better

I prefer 3.73's as a better all around gear, especially if you plan to boost or juice down the road.

Go 4.10's I had 3.73's in my 91 auto then switched to 4.10's. It made a big difference.
