been awhile since last post but been preoccupied with engine swap on my 99 382.Need input on drives, extention boxes, props. for 598-780hp motors. and what speeds to expect with what set up? jenks

Depends on the hp and torque peak of your engines. Generally, you want to prop for WOT about 1000 rpm over your torque peak. I am set up with Stellings boxes, Max Machine beefed XR drives, and 650 h.p. 600+ ft/lbs torque. I am still turning stock 28 Bravo props at 5400 rpm and 83-85 mph.

I think you would regret turning more than the above power in a Bravo 382 ... you will be breaking drives regularly. Not worth it in my opinion. If you feel a need to go faster, best have a look at some of the 382's that have been converted to Arneson drives.

arneson are my second year plan, I built the darts at 8:1 compression more power down the road. right I will dance lightly with some kind of brovo set up, xr/imco? for 08 poker season. motors peak torque at 743 @5400. 782@6300rpm. don't idol worth a damn, but sound cool!

I would buy some spare drives if I was you!!! LOL
