Wouldn't using E-85 as the fuel for a 250 Holley Blown 378 Mopar Small Block allow this smaller mill to best the output of the 446? Last edited by Bakaruda432; 12/23/09 07:01 PM.

Better heads will probably help. 250 is too small for high hp numbers on a big engine. Ran "Hey mister, something's wrong with your car, it idles roughly" - number one comment I got in Israel when daily driving a 70 Barracuda with a lopey cam. Currently working on - 1966 Dodge A100 van 318/auto Finally - disc brakes on the front. In the plans - rear disc brakes, B&M 250 blower
