What is this engine worth?
 

Have a complete 283 engine with 3756519 casting and F1230CQ on front pad. Engine turns over by hand but I haven't tried to start it. It's been sitting in a parked truck for years and is covered with mouse crap. What is this worth if I clean it up and sell it?

Colvin's book indicates those numbers are consistent with a 59-61 230hp manual transmission Corvette engine. What is the casting date code? Do you think it came out of a Corvette?

I know I am looking for my engine 9288 is the vin pad still intact showing a # , to answer question I sold a flint 283 motor last spring that was not corvette for $900.00 plus delivery . that one needed a rebuild .

sure about CQ being corvette 230 hp manual/ now to see if the vin # can possibly belong to a car that is still in existence a long shot. But worth the try !

283
 

I'd be interested. What is casting date?

Hi guys, where are the VIN and casting date numbers located?

This is lengthy and tedious, so bear with me. None of this is my knowledge, but quoted from Colvin's book.

You stated F1230CQ - this means Flint (MI) cast block, with engine assembled 12/30 - December 30th. CQ was for the 230hp 283 with manual transmission.

The 519 block was used in Corvettes in 59, 60, and 61, and maybe in some late '58s, but with a December build date, that's not where this engine was used.

If your engine has a VIN derivative on it, it will be on the same stamp pad as the build stamp you quoted as F1230CQ. However, these VIN stamping did not begin until the 1960 model year, and supposedly not until January 1960. So, check to see if you have that VIN derivative number on the stamp pad.

The casting date will be there, just a facet or two over from the block casting number you quoted as ending in 519, and is usually a letter followed by 2-3 numbers, although some are just 3-4 numbers. Find that and post it here. It will be dated before the build date F1230CQ from a couple of days to a couple of months typically. So, something like L39 which would mean December 3rd, 1959, for example.

Looking forward to hearing.:lurk:

Thanks Rhino, not so tedious... There are definitely no other numbers on the front pad, so no VIN. That tentatively makes it a '59 according to what you're saying. I'll try to verify that by checking the casting date tomorrow.

Hi guys, the casting date is L128. There is a very slight chance that the 1 is a 7 with a fragment broken off, but I looked at it with a magnifying glass and I think the 1 is just a bit cockeyed. Here are some pics of all the numbers.

I also have two other 283 engines here, but I think they're both truck engines. The first one is 3789935 casting and F07I3M front pad, and the second one is 3789935 casting and 83045 front pad. Can anyone shed some light on these?

Im interested. Send me a PM with your regular email to discuss. Or email me.

Okay, that means the block was cast December 12, 1958, which is consistent with the engine build date of December 30, 1958. This block, with the CQ designator is consistent with a 1959, pre-January Corvette engine block for the base engine.

Now, find someone with an January 1959 build date 1959 Corvette needing an original block and that block has some value. Other than that specific buyer, not so much. Since you're probably talking only about 800 total '59 Corvettes that could have been built with your block, and that some of them are destroyed, and many had different engine options, and many have still have their original block, you are going to have significant time and effort spent trying to find that rare buyer - but he or she is out there and might want your block. Good luck.

Just for fun, what heads, intake, and exhaust manifolds are on it? If you have a more complete 1959 Corvette engine, the price goes up.

A quick read of Colvin's book shows no 935 blocks were used in Corvettes. I can't speak to other Chevrolet uses, my book only speaks to Corvettes. FWIW, the 3789 first four digits are consistent with early 60's Chevy block part numbers.

3756519 F0606EB carb to pan running great really strong.
 

283 running strong hooked to a Muncie 4 speed. Willing to sell complete

Sean. Start your own thread, don't be a highjacker.

I would think 500.00 to 700.00 would be a fair price without having the engine torn down & checked.

Note that the thread is almost 2 years old, and was dead until a n00b hijacked the corpse.
