After doing some research of my own, and listening to the advice of Kevin, Larry and some others, not to mention the PIA it is tring to find a donar 5.0 in eastern WI, I've decided to go with a 351W block. I still want a S/C but the Kenny Bell is also just too much of a PIA to put on a 351W so for now its going to stay N/A. Larry H is going to build the short block for me with a custom Cam so that if I do put a S/C on in the future I'll be good as long as I stay under 8PSI. I go over that and I'll need a new cam. I know going this route will probably leave a lot on the table for this engine N/A but will probably save me money and time in the future by not having to change out the cam. Thanks to everyone for the good advice!
