If you want to spend the coin now, just go ahead and get the rear driven setup. With all the combinations of pullies, you will be prepared for any setup you may end up with in the future, ie. 370, 408, LSX etc. You will kick yourself if you don't. I wouldn't be too worried about wearing it out, everything I've seen from Magie has been top notch.

How much more $ is the rear drive? Unless they want a huge amount more, it doesn't make sense not to go that route. I don't know where things get ugly boost wise before you get into belt slip. I can close the flaps on my mufflers and see 9.5psi with no slip. Blower is a rear drive 2300. With around 10psi to work with, you can make plenty of power with room to grow if that's your desire.

I'm running a front drive 2300 and daily drive it. On a 3.2" pulley I'm seeing 11psi on a 370 with L92 heads and LEP blower cam. Driveability is good. I'm not for sure what the max boost is on the front drive but I think I would be able to pulley down and make 18psi. If you are wanting more the rear drive would be a better choice.
18psi from a front drive, that's very optimistic
You have the jackshaft one, is there anything about it that looks like it might wear out, or not last as long as the front drive, or do all the bushings/bearings on the jackshaft itself look like they will be durable enough to last as long as the rest of the blower will. Thats the only thing about it that I am worried about.
Oh yea, and is it easy enough find the right combo of pulleys for the rear? I'm guessing you have to pull the whole unit to swap them out.

IMHO I would start with the OD rear cog setup. I'm not sure but I don't think there are a lot of options for a OD ratio, other than the one you get when you ask for a OD rear.

The unit looks pretty stout to me. Just remember to go with the HD tensioner and install a support for it. One that bolts to the cylinder head.. And the CTS-V idler pulleys worked best for me. Do some research on jack shaft pulley setups for the 2300 from guys running them. Left Coast Joe and SuperSub are two that come to mind.

I thought 18psi would be doable?? Maybe not??

At what point do the pullies on the back end slip? That's one fat and tight belt compared to what is used to drive the front end. I can't believe that slip on the back end is a problem.

there are several different set-ups available. cog or ribbed.
I pesonally have a 10-rib rear overdrive, and a cog overdrive.
you have the chioce of underdriven, one to one, or overdriven.
The jury is still out on how much if any slip the 10 -rib has on the rear drive portion. How ever the noise level is greatly reduced over the cog.
As for power loss?? hmmm. still over 700hp to the wheels! only one in the truck world.
So far.
