I understand that if I want more hp I'm going to get low mgp but I dont want a 250 with 10mgp because if thats the case I might as well stick with a v8
Tom Lowe's 3 barrel mod got him 22 mpg out of his 250 pulling a 4000 pound chevelle wagon down the road at 75 with 2.56 rear end gears and a non-od 5 speed.
