Jeff thanks for the spec sheets.
ERIKV79 AND OLMAKO20 Can one of you guys to check some casting #s. I can break down all the details for you. First I need the casting # on the back of the engine block It will be at the rear of the engine behind the distributor where the bellhousing bolts to the engine block on top left or right. Next I need the casting # under the rocker arm cover it will be between the valves. an example of the engine block # is this (14010209) An example of the cyl. head # is this (3998997) I have been told that mercruiser took the L-82 Corvette engine and made a marine version out of it. This is how I can confirm it for you. From Jeffs spec sheets we know You have a forged steel crankshaft Forged aluminum pistons special camshaft and valve springs and a 4 bolt main block. Highrise aluminum intake manifold These are the best parts GM had to offer for durability. The main thing to take from this is If you replaced the engines with run af the mill rebuilts these parts most likely wont be in them. If they are just tired with alot of hours rebuilding the motor you have is the best bet. I have all the GM books and can confirm it thru the #s. Thanks Paul. PS If we get some tempest engine decal pics maybe we can get repros made.
