In late 1980's I put a tunnel ram kit on my 67 barracuda. It was from summit racing, Weiand tunnel ram with two 450 cfm Holley carbs. The engine was only a 340 with a Lunati Bracket Master hyd cam .480 lift 234 dur. but it ran great on the street and turned 12.20s at Cedar Falls Raceway down in Iowa.
Snap your neck, mega G-force launch, is all I want!
