March performance vs cvf pulleys on 340

The brand X guys have it a lot better in that department but thankfully Mancini Racing still manufactures a few. More spacers than shims but at least it's something...
Mancini Racing Crankshaft Pulley Spacer

thanks for the info! I found that too. I guess ill try the crank without the spacer first, i will probably go ahead and get the shims for the water pump pulley when i order the other pulleys and hopefully wont need one for the crank
