Ok, 1st Question... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a '70' C20, 3/16" frame, w/1ton suspention all around and leaf-assist-rear.
4spd top-loader-dayna trans,(actually, 3w/g).
Full-float, 8-lug dayna rear-end,(as I'm told), w/410 gears.

What is the highest gear set,(preferably Zoomy's or a better maker if there is one), that will fit the stock carrier in this rear-end?

*(I'm running 33" A/T tires and the 350 engine is pushing about 475hp so the rear-gear set has got to be as strong as possible! She can do wheel stands and get a third gear scratch w/ the 410's now. But I need better mileage! It's that, or I have no choice but to run pure alcohol in 'er.)

"HELP!" ...Please.
