Post Help with GM Part Identification

While tearing down my Chevrolet 350 Engine to replace the gaskets I wrote down the block and head numbers. Can someone convert these numbers into information I can use? Can you tell me the specs on these parts ?


Block #V0530FLC
SFS/79942


Heads # 14079261
E235

Thanks for your help.

Joe

The heads are from an '86 350.

Get the block ID from behind the intake manifold on the drivers side. They are large casted numbers next to the bell housing or tranny.

On the block,behind the altenator on the water pump tab should be letters.Three letter codes ex.CMJ car block TYZ truc block.Look um up in a MOTORS book they tell you what there out of.

Also look under the timing cover for #s these will indicate a high nickel or soft(weak) block.I forget all the #s but 509 is high nickel.010 is soft.Theres a few more but I forget.

the engine was built in flint may 30. the casting number will be on the back of block drivers side ont the bellhouse flange, there also should be a casting date located back there.the heads were cast on may 23 1985 (the same day my son was born)so I would say your dealing with a late 1985 350 probably from a truck cause the 350s didn't go into many pass cars in 85 and the F tells me it was more than likely a fleet vehicle;chassis and cab,taxi or police,schoolbus or some other commercial type vehicle

Thanks for the help ! We changed all the gaskets and seals except the rear main seal yesterday. I was plesantly surprised to find it has 4 Bolt mains. If the heads are from the mid 80's they likely have small valves and doesn't flow very high CFM.
