Low gear set 904, pro’s and Con’s

Hey Don! You're probably on the cusp of do or don't but, if you do upgrade in power anymore I WOUND'NT go with a higher SLR. I'd bet the 2.74 weakens the 904 some too. From what i remember the current combo is 4xx CID? But I'd think you have the foundation of parts to make 600HP without too much more trouble? Even given the combo stays the same, i'd leave the SLR alone, it won't do traction any favors IMO. I'd put a 4500 carb on it if you want to go faster!
