It's been 5-6 years since I did the last one and it was a Source kit. The bobweight IIRC wasn't anything to worry about but it wasn't that light. It had the heavy H beams and the precursor of the ICON forgings, RPMs, my own port clean up, matched 6bbl intake, and a custom Engle flat tappet with similar lift but more duration @ .050 and had a little more static compression (11.1:1). IIRC it peaked at 602tq with 570-something hp. I liked not having to mess with the oil pickup boss. In a heavy E body rag top with a 4sp it's a monster. It would be damn near useless in an A body...lol.
