Im trying to make sure I get the right 25% pulley for my LS3 swapped 72 Camaro and im hoping you guys might be able to help me out. Im looking at the Summit sum-c2503. It says its for C5-C6 vettes with an LS1 or LS2. My LS3 has the corvette front drive setup on it, so can I assume its the same offset as the LS1 and 2 vette front drive?
Also, because Im running the Vintage Air AC with the Kwic-Bracket setup, my belt length is different than the standard vette setup. Does anyone know how much shorter the belt should be when changing over to a 25% UDP? Thanks in advance for any insight.

 

U ddefinitely want the corvette damper to match up with the accessory drive. Can't help u with the belt length subtract 2" would probably get u there but that's just a guess. I use a string to measure belt length on custom setups

 

Hey newschool72 its tim Iam taking very good care of the gto I bought from ya still running strong she is in storage now for the winter.how you all doing.

 

Doing great Tim. Well , going in for my back surgery Feb 26th and a little nervous about that! LOL. Glad to hear the goat is doing well. I miss it,.

Bumping back up top for an idea of belt length difference!!! My PowerBond 25% UDP will be here Monday and I really need to get the belt length. I guess I will do the string deal for a measurement , if no one knows. HELP!!! LOL.
