Engine ID
I have a 65 327 coupe, and am having trouble trying to determine what size engine is currently in the car. I was told it was N.O.M. with a 327 365 horse currently. which I'm fine with it, I drive and enjoy it, but I would like to keep it as close to what it was intended to ba as possible. The engine apparantly was decked as the numbers on the engine pad are gone. Casting number driver side rear is 3782870, VIN 194375S14721, Plate on the passenger side interior support has style 65 437
then S2678, trim 408A7 then 900 UU.
It has a GM intake manifold with a number of 3844461 stamped on it. The carbureator is not stock, it had a new Holley put on just prior to my buying. If it makes any difference i bought AC Delco plugs last night R45 based on what I read here, it had AC 7 plugs in it., runs much better now.
Everything leads me to believe that most of the car other than engine is original, riveted brake rotors, 37 amp alternator, proper fuel pump, I did find a positraction warning sticker in the compartment where the Jack is stored. If anyone can point me in the right direction to find what the engine in it is now compared to what it should be would be greatly appreciated.

John...The Intake Manifold number is correct for Aluminum 350 or 365 Hp. engine and if the carb was originally a Holley that would also be correct. Check the exhaust manifolds numbers of #3846563 (left) and 3797902 (rt.side) which are correct for a non-air car of the above HP. Also you would have the a higher 6000 (6500?? not sure) redline on the tach.

As for clues to whether this engine block was even possibly put in a 65 corvette, pull the casting date of the block, you will be able to pinpoint the period when it was possibly installed. As for clues as to what your car had in it orginally (engine-wise) post up the tach redline, the oil pressure gauge range, and crawl underneath and see if the car has any signs that it EVER had the steering damper installed.

Has a 0-60 lb oil Gauge, 6000 redline, 2 1/2 in exhaust manifolds, steering damper installed intact.
Sounds like from what I hear, that the numbers may never never match but the car is worth keeping the engine and working with it. There are no oil leaks anywhere in the drive train, and runs solid except for various rubber bushings that are deteriorated from age. One more question then I'll leave all of you alone. The oil filler tube front passenger side has a small 1/2 in or so tube extension coming off of it, where should i run the tube. The manifold has no PVC, it has a plug center rear, Air cleaner has a flame arrester. This is a awsome web, first thing I am going to do after posting this is join as a member, thanks for all your combined help and knowledge.

Sound like you have a great start on a 350 or 365 restoration engine (depending on your heads-valves and cam).
As for the engine ventilation hose coming off the [correct] oil filler tube, that plugs into the "pcv" port on the carb [see below picture], which might not be present on the carb you are running now.

I was thinking of doing the P/S conversion also but I really like non-power while going down the road. Parking is no fun but I don't park much so no big deal! Did remove the idler pulley though to add A/C and move the alternator to the driver side.
