I agree with that. I was simply stating what I've seen people say about it right on this forum. That said, the GM transmission swaps would net OD ratios down in the high 60s. That's pretty impressive.
No doubt, and if were starting a build from scratch I'd consider a GM transmission and a host of others. But if you have a transmission already, or you are putting down some serious HP, the GVOD is a tried and true contender.
