Don't have PS, so that's not applicable unless I go to Hydraboost, but putting the AC back on.
Thanks.

Z-man: its personal preference, I like the compact design of the front mount and the shorter belt. The wide mount system has the AC comp and the alt over the front A-arms and in the way, also it puts extra heat from the headers on the alt and AC comp that will eventually degrade them. As for as hacking the frame, I have made modifications to improve every part of the car I have worked on so a small mod to the cross member to improve the accessory drive system is nothing.

Well said Neal. I was just going to say the front mount systems look much better... Now I know there are some good technical benefits too.

It's one from Whipple ('cause of my S/C) - simply made from an aluminum plate. This shot is before the pulley was bolted on in front, but you get the picture. If you have A/C, the plate extends somewhat over toward the passenger side to accommodate.
I don't see any advantage to moving everything one inch farther toward the front. The heat etc. is still in the engine compartment. The A-arms are still quite accessible.

Nice - but that left side looks a little tall regarding hood clearance...?
Update - I received the Vintage Air Serp Set-up yesterday eve. it was late, but opened the box just to check out the crank pulley... With a 3minute check, it is about the same size OD as the OEM 3ring pulley, but extends quite a bit forward. Looks like it will clear - but will be too close for comfort. This weekend, I will remove the OEM and istall to measure and post pics...
Zman's option is nice - but hey.. would that aluminum plate block engine cooling? BTW - what is that red plate on the crank pulley?

I am ready to head to the house to confirm whether or not the Vintage Air Serp Set-up fits. Thinking it will not. Anyway - it seems the lower crank pulley is the issue - why wouldn't they simply make the crank pulley smaller (which would clear easily) - then re-adjust all the remaining pulleys to maintain the same rotation speed. Is that too simple or am I not seeing something. If its torque, for a BB - I don't believe that would be an issue.
To back up, this whole thing started when I wanted to add the CS144 Alternator, which required the OEM alt mount to be adjusted. I think that mod is fairly simple - just cut and extend the outer edge of the bracket. The other issue was the Vintage Air A/C compressor mounting. I think Vintage sells a conversion mount for the A/C compressor.
And just FYI - March has a set of pulleys that converts a Vbelt to Serp. Just saw in Jegs, I will need to contact March for specifics and to verify. So - if I adjust these two brackets (A/C and Alt), I could maybe just use the Serp Pulleys to convert. ???
One last mod I may like to make is to convert to the Type II P/S pump. But I need to research that more for what that woudl involve.
Oh - and if I did the above mods, there is no Xmember issues. The above set-up woudl use the short H20 pump, and would allow me to use a Xmember spreader (.... which I just sold cuz I couldn't use with the current VintageAir serp setup)

The red plate on the pulley is my crank trigger. You can see the pickup on the left side with the blue wire.

Well I checked the dimensions on the Vintage Air Serp Kit. The OD of the pulley is the same as OEM, however it is over 3 1/4" long, which makes it hit the Xmember. 
Zman - not to get off topic - but what is a crank trigger?

I've got my 73's body temporarily mounted on the frame that has my engine. Here are some pics with no radiator, hood, headlights, or brake booster/MC. It will give you at least an idea of what they look like. I've yet to see pics of one of the front mount serpentine setups in a C3 engine bay.

It's just a different and more accurate way of timing the spark by putting a pickup on the crank itself in stead of through a bunch of gears. Replaces the points in a distributor.

I've always wondered that myself.

Vintage Air's Front Runner Serpentine System
I picked Up a 'ZOOPS' Front Runner, for my Small Block in My '72 Coupe.
Fits Like a Glove. No knotching the Cross Member.
Mine is the Front Runner with the Single Belt System. Real Compact & fits perfectly !
Good Luck !

Dont worry about a slightly smaller crank pulley sure V.A has done thier research so it all works right. Probably a diff sized WP pulley
Talk about undersized....never overheated on me yet.
Clean rad. good water pump low temp stat
