I have a 1970 Pontiac Lemans Engine - Block #9799916 how do I research it? I am looking for a harmonic balances (5 3/8" x 1/2" thick). Any info would be appreciated!
Your engine is a corporate "W7" code 350 V-8, according to the block code you posted, with a 2-bbl carb and 3 speed auto.......... You can get new harmonic dampers from many sources from $50 to $500. Do not go cheap on this item if you intend to keep this car. Pioneer Street Performer 872011 is a good, economical piece. If you intend to modify this engine in any way, however, I would go for an SFI-approved part..........
