I'm building a D16 with Z6 block and Y8 head of which i had the whole bottem end balanced. My problem is that i can't find the z6 balanced pulley. (I actually think i never got it back from the machine shop ) I do however have a Y8 pulley i could substitue for a little while.

Are these pulley's any difference? Belt sizes? Weight? Geometry?

Thanks!

heh thats kinda funny you are doing just the opposite of me, i have a y8 bottom z6 head, and the pulleys are different part numbers, what the difference is, i have no clue... but you could prolly get away with using it...

 

same chet, i have used them both, same size and everything, they both have the ac and PS on them, and have the same number of grooves. I dont run them anymore, i like teh CX ones that just run the alt. they are the CTR N1 pully for SOHC's
