Bossvette,
The serpentine system from March was pretty much a plug and play install. But, like with any aftermarket modification you will run into a few problems. As far as the water pump, yes it is CCW. An 84' vette water pump will work fine. I bought the SB Front Mount Serpentine Conversion Kit (March part# 20260). It came with water pump, GM Type II power steering, tensioner, polished 140 amp alternater, polished AC and all hardware (including screws, bolts and brackets). The polished covers provided by March made the whole system look nice except for the water pump. I went ahead and spent the extra money and bought an Edelbrock high flow polished water pump for an 84' Vette. You can get less expensive ones; however, because I am not running a fan off the water pump along with putting out 487hp I didn't want heating problems. To help with cooling I also installed a Be-Cool radiator (polished) with twin 11" electric turbo fans (polished) and a 160 degree thermostate. The only additionional items you need to purchase is a 62" 6-rib belt and the remote resevoir (chrome of course). The only problems I had with the installation is as follows:
1. One of the water pump bolts had to be cut down 1/4" - or replaced.
2. The 3 screws attaching the AC plate to the AC were 1/4" too long - replaced with chrome screws.
3. Use your old PS pressure line and reverse the angle on the line at the PS side by 135 degrees.
4. Had to get the remaining PS lines made - prices for line at March are way over priced. 5. Also had to get the AC lines made. March provides chrome fittings for the AC in the kit. I used the fittings off the old AC lines for the other end and had braided lines made. Looks sharp.
Hope this helps. Please let me know if you need additional information.
