Stall Speed

[mil_act02]

I've got a 383 stroker (est 400-450HP) w/a 4x4 cam, 700r4 tranny, np208 case, 4.56 gears, and 38" super swampers. I only drive offroad. Usually drive through dirt & mud, but also on rocks. Worried that if I match a stall to the cam I will have to use too much rpm when crawling on rocks.

yeah too much stall will just heat up that tranny in my opinion,, i would go with a little more than stock, with one of those b&m radiator type coolers

I have a 2000rpm stall in front of my TH350. On the trails, mud, and climbs it does quite well. There aren't too many rocks around here, so I can't tell ya how it works in that regard.

stock stall speed in a fullsize with a 700r4 is abour 1400,
i wouldn't go anymore than a 2000 stall converter, a 1600 stall works very well with just about everything.

2000 stall- corvettes, 9C1
1600 stall-just about anything with a 4.3L
