Stock Diameter Aftermarket Balancer
Almost everything I see available is 25% underdrive or 10-15% overdrive. Seems weird with as many truck blocks being swapped that there is a lack of options for the truck pulleys spacing.
If I went with a 25% underdrive, I have to replace some pulleys for alternator and powersteering correct?
I went with the summit 25% pulley for my Ls1 and it's a very nice pulley. No alternator pulley and I have zero charging issues.
Might give the ASP camaro pulley a try its 15% under pulley. Also, looking at the Romac pulley that texas speed sells.
