I have just bought an LS2 front accessory drive I just installed on my 5.3 LS truck motor and I put on an LS1 Fbody HB and it was not inset enough..
I also have this LS7 HB right now and I stuck it on there without tightening it down at all and it looks like it would be TOO inset.. hard to tell.. but looks that way.
I tried searching all on here but to no luck.. and for some reason the LS2 HB is out of stock everywhere I look!..
this is my LS7 Hb..

and what my LS2 drive looks like.. which I THINK its an LS2 drive(got it used)

BUT it has an LS1 waterpump on the front.. which I also have an LS7 pump if it has to be run to work with the HB.
please let me know!
thanks guys!

Well, let's see. The LS7 and LS2 use the same front accy drive (FEAD) system. However, the LS7's crank snout is 1" longer due to the dry sump oil pump. So, how does GM make the LS7 balancer fit the same FEAD that the LS2 has? I don't know the answer, but I'm pretty sure it won't work.

im not in the know about that how do you mean?..
I considered the Professional Products balancer(nervously) since it was readily available.. keep in mind this thing is a street car mainly.. little to no track.. it will be my daily.
