Add a Dana 80 to the list. The Sterling wasn't to happy....

I think the same rear end swap we just did in mine would probably seal the deal on it

Ya, I hear the rear pinion had a blow out.

What RPM was sustained here?

Fast-6.0 · Jun 16, 2013

The truck has 350cc Injectors. It was running 4400rpm down the track. It has 3.73 gears and that run was in 1st gear 4 high. We expect it to pull more rpm at low altitude. As we really want it to run right around 5000 down the track.

Needs 4.10 for high range with 19 mph lock up. 3.73s are too fast

Yeah I'd be surprised if he could hack 11.5 to 1 final here in the Midwest. Because he will need duals to compete, and our sleds are a little tougher. 4.10 high 1st is 12.7 final. Much better. But if he adds duals and goes to 35" tires like he will need to compete, then likely he will need to gear even lower. Like a 4.56 and run a 14.1 final to have the rpm were it needs to be and still turn 35" duals. Maybe even 4.30 gear and run a 13:3 final.

Time will tell.

My prediction is the sterling will be swapped out along with the 3.73 gears.
