Wow I didn't realise iI was going tto upset so many ppeople. I haven't checked to see if rrock auto hhas a big selection of dinaflow goodies. Other than the fluid they are known to leak. And so of course iI can just change the tranny and rear end like that's simple. And of in my search I just happen to find one of the best big blocks out there and yes it's a buick. So I try to ask some people how love this brand for advice and catch flack from purest that probably take their cars from town to town on a trailer.
