Dutch,
No offense, but I think you are going to have to come up with a lot more than an LS1 to get someone to trade you for a "Cammer". But if you do find someone to make that trade please let me know who they are because I have a bridge I would like to sell them.
Have a good one,
Dan
p.s. I think all of the SOHC 427's were sideoilers , but I may be wrong.
