I've seen posts showing how to attach LS1 to LS3, but not the other way around.

Will a LS3 Accessory drive fit on my LS1 (01 WS6)? If so, which version?

Balancer...space out the LS1 balancer 3/8 of an inch with a washer and ARP bolt or will a LS3 fit proper (next question may affect this answer)?

I plan to keep the A/C, I'm assuming I would I need the LS3 A/C compressor to be aligned with the balancer?

Water pump issues?

Anything I'm not considering?

Thanks

LS3 from a Vette or Camaro? BIG difference...

I guess that's one of my questions...which. I read that the cts-v ls3 accessories drive will fit on a ls3 inside a fbody. More to consider with an ls1 though

Basically, I need to adjust the spacing of the fanbelt from the motor and my ls1 accessories are wearing thin...but ac is strong.

You just have to remember to keep the spacings coordinated. ALL short (Corvette), ALL medium (Gen 4 F body and others) or ALL long (Gen V F body and all trucks).

I get it...don't mix/match. I plan to buy a new kit. I'm just not sure which ls3 kit will fit in my fbody ls1 and if the ls3 balancer will work w my ls1 a/c unit. I'm also not sure if I'm missing something with this plan either.

thanks again
