Ratickle---nothing to muff the exhausts--I guess they are really called semi-dry----the water mixes with the main exhaust at about a inch from the end/outside---they were not really that much louder OR I'm getting deaf-hahaha--I also learned today that the GM gen5 and Gen 6 BBC crate motors came...

OK---long story short---found a piece of a broken snap ring inside the distributor---stuck/attached to the magnetic pick up-----it would move and lock up the spinning gear----bottom gear was brand new--keyway was good--Distributors don't have snap rings, so we determined it was picked up on...
RSchap1---right now I guess it has to be anyone of the above you listed--my engine tech does not want me to touch her anymore and to bring her in for him to look at---he believed it was the ignition boxes also-but we were wrong----AND RATICKLE you are right--thank goodness I live in Florida and...
OK---changed over the ignition system to the MSD system they sent me----SAME F------- PROBLEM....backfires out the exhaust----then just spins like a top---give her a squirt of gas---boooom out the exhaust...........this is the 3rd brand new ignition box I have put on her--it can't be the...
OK---after several weeks of waiting-KE Performance phoned and told me the ignition box was no good--wheeeew!!!!! I'm glad it was that-----So they are sending me a MSD anolog vs. the new digital boxes so when I install this box-I will let you know if the problem is fixed!!!! Thanks---Mike-Tampa Bay

MOBILMERCMAN---Thanks soooo much for that info----I have learned to save a buck--cost me more bucks---I have to pull out the engine again----AND I have learned to be aware what U wish for!!!!!! Thanks-so much-----Mike--Tampa Bay !!!
Thanks----I have been doing some re-search and am learning some engines are balanced internally and some externally and the 496 flywheel will not be balanced the same as a 502---Soo I need to pull the engine and buy a 502 flywheel!!!!! Thanks again--Mike---Tampa Bay
Engine is finally in the boat--BUT has a bad vibration--trying to save a buck, I installed a barley used 496 flywheel on this new 502!!!! Is this flywheel an OK fit or could that be the vibration-----engine is a brand new marinized 502/502!!! Thanks---Mike Tampa Bay !
