Yes,the balancer is the key on the spacing, It’s a little confusing but if you go on Holley’s website their documentation is excellent and explains the differences with many pictures and also gives you the Holley,GM, and other part numbers for all the pieces involved including AC comp,PS pumps,Alt, idlers etc. It’s the best resource I found when I was getting ready to buy.

My LS1 came from a 2001 Z28 Camaro, and thus the balancer and original accessories were on the 'middle' position for the belt. I think Corvette engines have the 'closer' positioning for the belt (closer to the engine). Does that mean that all the components are farther back towards the engine? What would I have to change on my LS1 to use the 'corvette spacing'?? (I need as much room as possible between engine components and radiator.. I have the AutoRad system for support/rad/condensor/fans/etc... )
Is it the crank pulley/balancer that establishes the positioning? Would changing out my crank pulley allow a closer positioning of the components? (Still learning all these LS details)..
