4 speed od or 5 speed

^^Which is why I asked about ratios. Might as well ask about torque handling too.

The 833 O/D has very wide ratios and is more suited to engines with wide flat torque curves that begin right off idle. Like slantys, and maybe Magnum 318s.

AS soon as you put a healthy cam in, You are moving the torque peak up, and tightening up the powerband. This tranny will handicap you there.If you bring the compression up at the same time, it may not be quite as bad but really,behind my 360 with the 292/509 cam it really sucked. Behind the same engine with a 223* cam it was sorta bearable. That's when I bought the GV and began using it as a splitter. Problem solved. When I moved to the 232* cam, I shelved that tranny. Instead I obtained a 3.09 low/direct4th gearset(thanx to Passon) , and put the GV behind that. Now it's a 5 speed with progressive ratios.
And that's what you need with any small cid engine. So that takes us back to your Dak box. If the ratios are progressive, with non-granny first gear, and you keep our engine power to within the trannys limits, I think it could be sweet. But if a granny gear is in there, depending on where 2nd is, it could break the deal.
