Just traded a 2001 Baja 302 with T 496 MAG's for a 2004 38 Special w 496 HO's. Won't be delivered til May 1. Figure it will run in the low to mid 60's and like you want more(speed).  I appreciated your review of procharger intallation.  Would like to do myself without pulling engines but your story is making me think twice.  Because engine compartment on the 38 Sp has room for a generator, I hoping I will have plenty or room to work on the engines.  How is your 496 HO w/procharger running now?  Nice web page.
