Aluminum 833OD behind a 440...your thoughts

I have one.

It's in a d150 step side, none the less.

I don't drive it a whole lot, but I have driven it plenty and driven it hard.

No issues.

Truck was born with a 225 and the 833 O/D.

Someone swapped in a 1969 10:1 440 that sounds like it's got a small to medium cam.

It's got headers, a performer intake and now has an Eddy 750.

I can only assume the factory gears are 2.76 in the 9 1/4.

I do spend a LOT of time in second gear, and can't imagine first would be very useful with any more than a 2.94 or 3.23 rear.

I do shift aggressively into 2nd and 3rd, and it will spin the tires into both.

Power shifting into O/D is not the best idea regardless of what trans you are operating.
