only done one test drive so far but it's just right. full assist is firmer than a stock 60's P/S setup, not over boosted, but still 1 armed parking lot doable. with the assist at it's lowest it's almost as if it's off. i used a kit from EPAS Performance. it's a very nice set up and if i'd used the stock column, and just followed their instructions, it would have gone easy. since i had an IDIDIT tilt column i wanted to use, i managed to over complicate it, much to my enjoyment :D. also the floor plate for their kit is only for a 65'. they didn't realize all the different A-body floor plates that were used. i've sent them the info to correct that. i just made my own from 3/8" aluminum. as far as the alternator, i already have a 75A powermaster with a lot of re-wiring. supposedly this only draws 9A max
