ls3 crank pulley

Right now on my lsx 376 swap, I noticed the ls3 crank pulley doesn't line up with f body accessories that I bought. So will a ls1 crank pulley throw off the balance or will I have to use ls3 accessories instead?

Re: ls3 crank pulley

Pretty sure you just need to get the ls1 f-body pulley. Shouldn't affect anything as long as ALL your accessories are the f-body ones.

FWIW there are no "ls3" accessories, they are model specific.
