This set up is a great improvment for the ol' 300.I believe Dirt Wheels did a review on the Powroll 330 kit.I had a 330 Sparks and it would beat many 400's.

:devil: I have a 1996 honda 300ex, and am intersted in working it out. Where do i get and find information on the Powroll 330 kit? I am looking to try to figure out how much bang for my buck i am going to get, and if it is really worth it. All my friends have 400ex's, and Craptor, which always seem to be falling apart or, nto working or something wrong with them, but still faster. Well i am loking to get some speed to toast them or atleast keep up. :devil:

i have the 330 kit, with oversized valves, cam, powroll header, and cobra end section. I also messed around with the gearing, im running a 14/33 with 20" turftamers. I pull on and beat stock 400exs, warriors and blasters i eat up, and the banshee smokes me once hes in like 3rd or 4th gear. I would say that this is the best kit, but it runs a little hot, so i would plan on fabing/buying an oil cooler. I am very happy
