How fast have you gone 1/4 mile with the special? Jamie at CPP said he for 624hp with his special on fuel. That theoretically should put you well into the 12's. I'm looking to go 12s in a quad cab dually so I'm pretty interested in what times people have run with their mods.
That combo will be awesome! A vp44 truck will never need more than a S475. They just don't have enough fueling capability to need anything bigger. If you get Diesel World mag, check out page 121. My boy Johnny Gilbert has a 6 page writeup in the April edition on his 834hp vp44 powered cummins. If I wasn't a sledpuller, I'd be running a set of Gilbert triples myself. I'd recommend those. LOL Big bucks though.
