Since this engine is my "tribute" to the L88, I'm going to shoot for the same .050 numbers as the original L88 solid flat, which I understand to be 264/270 @ .050. I'm also using a 3.75" stroke crank (but 4.600 bore) and a set of aluminum heads (Pro Topline 320's). I am shooting for .725 gross lift or so since I'll be running shaft rockers. With the short stroke, I may end up moving the LSA to 112 or so to make it a bit more driveable.
Thanks for the recommendation, though - I'll be sure to include that when I talk to Harold next time.
