you can read the # off of it.
depending on the setup, youll want at least a 31-33 in the front.
i run a lil larger in the rear at 35-37.
all to often youll find a 28 in the front and 31 in back. sometimes that just dont work out.

 

I just bought some 35 squirters a few weeks ago. I'm gonna go look and see whats in there already.

 

It has 31's front and back. I'll swap the secondary one out for a 35.

 

The B&M governer recalibration kit works very well on those. I've used it quite a few times. One of my friends went 10.64 in his truck running it in drive and going off idle. I had set his to shift at 6700rpm in drive.

 

Cool! I'm gonna go look for that. I don't have a kickdown cable setup, does that matter?

 

Not really, but I highly recomend using one. They not only work as a kickdown, but under wide open they also give line pressure a boost. There are shift kits that eliminate them which is nice too.
