Quick answer for JW ultra-bell fitment?
Anyway, I saw two part numbers: one for the standard Th400-GM and one for the TH400-LS motor. Which one is more adequate for an LM7? I was thinking the LM7 is an LS style engine, but I want to be sure before I buy.
I'm borrowing a JW for a TH350 and I noticed that the fitment requires some trimming due to some small bolt heads sticking out behind the block. I'm hoping the LS type BH will fix this.
Thanks for looking,

"Some distributors may stock the LS part number and some may stock the traditional GM engine parts numbers. Either part number will fit the LS engines. They are the same exact item. "

I find it funny that Summit Racing sells the LS part number for a lot more than the other p/n, although they are the same.
