Hey guys, about to pick up a 1500 RCSB on a 2500HD frame. Going to be a fun build. Looking into what the solution is for a race transmission is these days as I've been out of the game for so long. Last time I was around here, I heard a guy was using a 48re with a manual valvebody. Just looking for something that will handle a ton of juice and shift fast. I also read somewhere about a dude using a Lenco trans. Any insight here? Anyone here done a conversion or know what it would take? Thanks.
