Starting off w/ Dart SHP 400 block new from factory. I'm thinking of using parts from my 383 (20 hrs.), such as forged crank, 6" rods, intake and alum. heads 65cc (AFR 195 Elim.). Builder says piston/ deck probably .020 w/o decking. Engine to be installed in 18' boat w/ Alpha SS drive.
How much main/rod bearing clearance? What pistons and comp. ratio( 93 octane)? Ring composition and gap? The Bullet cam from old eng duration 230/238, lift .540/.525. Will try to att. cam card. Any help I can get would be great. I contacted a member who does eng. builds. He was very apologetic and said sorry, too busy. He suggested post on forum.
