If I do a GEN 3. I will check out the trans you suggested. As for the 2004r. That's for my BB stroker. The reason for using that trans. It's small and fits easily in about anything. I can just basically change out bells flexplates and converters. I can use it with any engine I want. Yeah it is a little pricey. But 1 trans that I can use on a small or BB. Thanks for the suggestion.
