Greyhound gears and a smooth engine if you're going to drive the damned thing farther than your local Sonic . . at freeway speeds . .
As for the "Fake Blower", just more crap hanging off the accessory drive you'll need to fix somewhere 100 miles from where you want to be . .
IF . . You're gonna cruise or drive a street rod very far frequently, keep it as simple as your talent and ability to make it work. Hot Rods and Street Rods are two different things . . .
