figured we could get more boost with the e85 and around around 5-7 pounds of boost saftly. i been lookin at a a couple places that sell carb kits,but ones around 80 and others range from 290 and up. lookin to convert the 850 marine because it seems to be better to run with the supercharger going to be a street truck pretty much a daily driver. but mite see some track but nothing to serious just for fun. may run nitrous later but not for awhile.
not sure if there is anything else to be said but can proivde more infomation if needed.
