Holley accessory drive LS3

[DT69Cam]

Did you guys have to trim 1/8 of an inch of the water pump bosses (LS3 crate engine)as the Holley directions suggest for the accessory drive set-up ??

I used the Holley full accessory set up on one engine and it kept throwing the belt. This was an LS3 connect and cruise package. I had to do some trimming to the tensioner attachment on the water pump. I think that's what I had to do but cannot remember specifically....

At best, check your belt alignment carefully with a straight edge, I know there was an alignment issue.
