Looking for anyone with resources to find out what engine I have. Told it was a 250, pulled from a 64 chevy pickup, engine was not original to the truck. Casting numbers near the distributor are "F1210PV" - couldn't find any info on PV rpo codes Block number is "3850817" which comes back to 1962-1978 230/250 "CON 2" followed by "L34" - I****ume means December 3, 1964?
PV is not an RPO code, its an engine****embly code.... L34 is the date...so December 3rd of 1964 for a 1965 model year...its a 230 ci w 3 speed manual.
Dang you're quick. Thank you! I was about to add a picture of the cylinder head casting number, which is 3872708, also indicating a 230. I just bought this engine locally. I intend on using it as a transplant in a 1974 Sabre Craft boat. It has a Mercruiser 165 (GM 250) with a cracked block. I'm going to go check the casting numbers on that real quick to find out if it's original to the boat, as the cylinder head casting number off of that engine is "3824435", which comes up as a 194 cid head...
Casting numbers off the engine in the boat now: Distributor casting: "F05095W" Block Casting: "3850817" CON 2 followed by code F44
F 4 4 is June 4 1964 casting. F0909 build date is June 9th. 5W suffix is not likely to show up in any books for cars or trucks, since it's a Marine engine, eh?
5W has to be in a book somewhere... It's more than likely a 1974, not 1964, right?. I mean the boat itself is a 1974. Also it's not uncommon to find these Mercruisers swapped with truck 250 engines, they're identical.
If the boat is a 74, then yeah, it's possibly a 1974 engine. Although Chevy went to 3 character suffix codes in the 1970 model year. A 1974 truck engine would have a 3 letter suffix code, starting with T. Such as TAA. A 1974 car engine would also have a 3 letter suffix, starting with C, such as CCA. I don't know what book lists Marine engine suffix codes. Good luck...maybe something from Mercury?
Thanks for the help guys. Either way now I know I've got a 230 from 1964 and a 250 from 1974 with a 194 head. Wonder if swapping crankshafts would be worth all the effort or not..
Your "new" engine looks like it might have a lot of miles on it. If you have the time/money/ability to take it apart and work on it, turning it into a 250 might be worthwhile. Kind of depends on your situation, which we can only guess at.
Oh it certainly does. You can see each rebuild through the different colors of paint. It has .030 over pistons, aftermarket lifter covers, freeze plugs have been replaced, silicone everywhere... Definitely rebuilt. Engine is on the stand, completely apart minus the crankshaft. Was a good running engine, definitely lots of miles. I planned on a quick hone, rings, and have the head rebuilt locally. I have to pull the 250 out of the boat before I continue. I might swap the cranks..
Generally when an engine is "rebuilt", the block gets cleaned well enough to remove all the paint...so I'd say that engine might have been "overhauled", but more likely it was just worked on enough to keep it running. If it still has standard size pistons, it's probably due for a rebore, if you expect it to last a long time. But if it won't get a lot of hours on it, might get by with just new rings.
Cut the ridge out of the tops of the cylinders before re-ringing or you run the risk of breaking a top ring.
Can anyone glean any information from this number? f00508ccg Asking for a friend so I don't have immediate access to the other casting numbers. Based on what I've read this sounds like it should be a car engine but it was in a boat. A '70s model aerocraft. Any information will be greatly appreciated
CCG does not show up in a quick internet search of car engine suffix codes, so it might be that it's a boat engine....chevy did sell lots of 350s etc to the boating industry Get the casting numbers off the back of the block, both the long number and the shorter alphanumeric date code, and then we could tell you a little bit more about it than being****embled in Flint on May 8th. Also look for another stamped number on the front pad, if it has one, and it's a partial VIN, then it was likely installed in a car or truck originally, and that number would give info about year,****embly plant, etc.
