Here is my intake after I cut the exh heat crossover so it would clear the Indy valley plate. Really is not alot you have to trim off. Ron







Maybe it`s me but why the dual plane when a 520 should already have earth ripping torque and an open plenum I would think would neutralize some of that...........





Yes Thumper its you. Just kidding. I went with the Indy dual plane since mine is a street car and it has good low end but everyone I talked to said it will flow big time for a dual plane and be able to handle my 493 with no trouble. I would love to try a single plane one day and compare it. Ron
