same old chevy starter problems
the screwdriver test was only to confirm-no lock up. I have used five known good, h.d. and small high torque starters- starter is not the problem. yes i pulled the plugs sseveral times-no hyd. lockup or leak of any kind. eng. is a 305, .030 over, 480 lift, hyd. new w/ new lifters, timing chain gears, rod & main bngs,oil pump & etc. I am jumping directly to the starter hot lew & grounding to the starter & or block. bendx teeth engage turn eng slowly but do not disengage. I have pulled, dissambled & checked eng for the second time...here are my clearances: Piston to top of head .040. valave to piston .valve to piston .080.piston to bore .009. ring end gap .015,.015,.017.main bngs.0025. rod bngs. 0025. rod side clearance .020. thrust .007. I have double checked bores for tapew w?telescoping/mike gagues. my thoughts at this time are possibly a warped crank... anyway, my solution to this problem is to back up & regroup....I have set this "pile" aside & started building a 350 many thanks for your suggestions. this eng is under a voodo spell.
