I am gonna start breakin into the engine here soon, I know i am gonna go with the 426 piston, a cam, a carb, head work, exhaust. I just need help on what kind to get. I see post on it, but not really as one issue.
Does anyone have to looney tuned exhaust, and if not its a TRUE dual for the 400ex?
Who should i go with for the piston?
What would be the best cam to go with?

Thanks for everyones help

 

je, or wiseco piston, hotcam stage2, ported and polished head, and umm whatever exhaust you want, i think the fmf powerbomb is awsome for a header. you will have to look at some stats for exhaust or something there is alien, scorpion, curtis sparks, drd, fmf, hmf, dg, and many many more. o and also what comp. ratio are you planning on?
