If you add catless headers you will have less boost too.
Stock lt4 pulley belt will not be same due to spacers.

I would do that, but have been warned that once the OE pulley is removed and replaced by an aftermarket one, the balance is not going to be perfect and eventually the stress is going to take its toll on the snout. There is also some glue work to do, right?
Not saying that it is not being done...it is, but if I can avoid tinkering with what has been prepared at the factory, then I will.
Question is, can I find a suitable lower unit which can fit.
Did I miss something in the ATI catalog? All of the pulleys there are 6-rib?
I must be missing something, because it reads that they fit LT4 engines
