Well I thought I'd build another plenum. Real short runners to help the top end. Hopefully still have enough torque to get up on the converter :? . Made some velocity stacks out of exhaust pipe, a trusty machined holden 6 balancer and a press. Got the flare out to a flat bellmouth with the balancer then pressed it straight on a peice of flat plate to give it the curl. Not the prettiest but should work.

It ran a best of 10.55 and best mph of 136mph so well see how the plenum performs. If anyone missed the thread in the drag racing section heres the video. Cheers
