7 Second 572 Hemi.

Hi, have had the 572 Hemi 16 years, It's an Indy. Have been inside it many times. No problems until, this time. Had it honed by a Mopar only house. Good folks. Used them many times. Bore 4.5005 all over. Mic'd Pistons checked good. Piston gap .004-.005. New rings, full set same mfg. as I always used. Gaped .004 per inch of bore, same gap as always. Checked and re checked. Oil ring rails measure .050,, excessive, but,, with in tolerance. Same .050 as my other 572 engine with No problems. Valve guide I.D. s measured and , good. Valve stems mic'd, all good. New valve seals installed same kind as always. On start up engine Smokes an incredible amount and doesn't stop smoking. Same oil as always. Same everything ! Pulled engine apart. New rings ! Re checked EVERYTHING. Reassembled, SMOKES !!! . Never had it, or any engine do this before and have done over 50 in the last 40 years. Haven't put a load on it as of yet BUT,, have never had it, or one do this before. Opinions. Thanks, D.y MAGA !
