    Default What year is my 460 ??

    Got these numbers off the block D1VE-6015-A2P and what all numbers and letters stand for. i think D1 means 1971 is that right.

    Good guess is going to be early 70s.What do the numbers on the head read?Are they stud rockers(68-72) or pedastal?

    They used that same block from 71 -78. It would be internally balanced. The external stuff happened with the 79 block. which would be a D9 code.

    No, not exactly. D1 is a reference to 1971, but this is not indicative of when the block was cast (nor is it necessarily the year model of the engine) because the number you are asking to interpret is not a date code; "D1VE-6015-A2B" an engineering revision. The D1VE engineering revision cylinder blocks were used from 1971-1978. The actual date that the block was cast is located in the lifter valley and is alphanumeric.

    Regardless, the actual year of your engine is not particularly important since all blocks can pretty much sustain the same power levels as far as the stock blocks go.

    The head casting number is on the outside of the head, along the valve cover mounting rail, and based on the numbers you posted my guess is that you will find D3VE-A2A.

    My dad(RiverRacer) says that Head was cast on August 12, 1976. MCC is the Michigan Casting Center code(where it was cast) vs DIF(Dearborn Iron Foundry). Probably a revision D3 casting.

    Would doing a valve job do me any good performance wise vs the stock set up.

    I asked RiverRacer. He said if your Heads need servicing it might offer an improvement, but it depends on how bad the Valve faces and seats are. If they are worn out and there is no seal, you might pick up some power with a good, radius valve job. Maybe a little more if you put in CJ size valves and did some porting and bowl blending, BUT, your not going to pick up a bunch without changing a LOT of parts and spending some cash(probably Cam change as well as Valvegear, Intake, Oil Pan & Pump, Ignition and Carb).

    He said to tell you just to drive it and enjoy it. When it gets sour, think about pulling it down and redoing it then.
    That's what I'd do myself, to.

    Hope that helps.

    Found the numbers on outside of head they are D8VE-A2A i looked 3 diff times cause ive been seeing there is no such thing as D8VE as ive researched so its probably D3VE. Can anybody tell me anything about these heads. This winter i want to put in a new cam, and do a valve job what would you guys suggest, i want something that gives a good sounding idle i love to hear that lobe sound. It has a edelbrock torker 460 intake, edelbrock 750 carb, accel ignition coil, and some aftermarket exhaust manifolds not sure what kind but they read H-2985.
