Methanol or E-85??? 5 years now on E-85 powered drag motors, never once thought of going back to gas... Street use is gonna be different then a drag only engine, think I'll defer to Mr. McCarthey for specific suggestions on a street BBC....

However, gear drives IMO are no good at all, way too many bad harmonics running through the valve train...them chebbies already have enough trouble with spark scatter cuz they put the distributor on the wrong end of the engine!!!!! We haven't gone to a vacuum pump yet, don't know that we're going to anytime soon....
