(Relocated this post from the 'Good Morning thread' at the request(?) of the Thread police)...

I've been on the phone with Holley tech support several times, trying to get enough information on their LS accessory drive kits to know what to order (between the 20-131, 20-137, and 20-185) OR try to find the best GM numbers to order...


If any of you have used any of these kits I'd love to hear about your experience. I'd like the components to be 'tight' to the block, which is what the 20-185 provides, but also not to protrude farther towards the front (and the rad/fans/etc).

My car is a '57 Nomad, stock firewall, sitting on a custom aftermarket chassis (Billy Dawson frame), with an LS1 from a 2001 Camaro Z28 / 4L60E...
