Sure, It looks like the AFR heads I have do include the accessory mounting holes so that may improve the odds of a factory style system working. I'm not in any hurry, as the existing v-belt system works ok.

Chris, I hear ya on the reverse rotation water pump, I know that may be a necessary change depending on the system I end up using. Seems likely given the typical wrap arrangement. With the PS pump I assumed (there's that dangerous word) it would be ok with a pulley swap since it's essentially a modern style part. Plus, the location and wrap of the V setup seems the same as most serp systems I've seen, I believe...

I'm not necessarily aiming for a gm setup, but if that's the only budget approach that works well and allows me to re-use some parts, then so be it.
