LS3 with LS1 accessories? Sorry for the repost, but I am putting this one on the Gen IV list also...
I am in the middle of an LS3 install in a 1972 Chevelle. I have a donor engine from a 1999 WS6 (used for mock up, fab, T56 and accessories, etc) and have a new LS3 376/480 in the car. When I went to bolt up the F-body accessory drive (which I assumed would work) the belts do not line up with the crank pully or the water pump pulley (the LS3 stuff is about 1/4" closer to the engine). So now I either have to get an LS3 accessory drive or bolt on the LS1 water pump and pulley to get my F-body parts to work.
Question - since my assumptions are not quite batting 1000 lately, is there any reason the F-body LS1 water pump will not work with the new LS3? Am I better off getting a new accessory drive? All the accessories seemed to work off the donor car - so I don't necessarily want to replace them yet - but I really wanted to keep the brand new LS3 water pump. Any suggestions?

I just found an old post that mentioned all that needs to be done is to pull the pulley out about 3/8" to have it line up. This, combined with an LS1 crank pulley should do the trick. Anyone know how to pull the pulley out without screwing something up?

u have to go with the crank pulley off a fbody and all the accesories.
if u have ls3 accesories, u must use a ls3 corvette crank pulley to run all the accesories correct.
or if can have some aluminum spacers made for the water pump to space it out further used with 2 pairs of wp gaskets may work

Well, I have a complete F-body accessory drive, minus the water pump. If the pulley will pull out about 3/8", and I put my F-body crank pulley on, everything will line up. I just want to hear from someone that has pulled their water pump pulley out a bit to line it up with other accessories with some tips on how to do it, and if it is even possible (previous posts have said so without any directions).
