engine codes

[enferno]

i have a 66 coupe with code 6R07A182238.

all the numbers ont he body math to this, so we all can agree that it's a 289 w/ a 4v.


however, the engine in it is a 2v, so i decided to check out the number on the block. passenger side, right above the starter, the code is

C8AE-6015 B

is this not the code for a 69-70 302?

i've also heard that near the end of the production for 66, they used some 302 blocks as the 66 289 blocks stock was depleted.


some help would be very appreciated, as i am trying to find some info out about my car

68 was the first year for the 302 so im pretty sure they werent in 66's

also the C8AE # is a 68 block

i agree on this in both cases, so i suppose i have a 68 302 in my 66 coupe?


it also has stamped 302 1m in the lifter valley



edit: i think i just answered it for myself. 289's were stamped with 1m cranks, and 302's with 2m



thusly, i have a late 1966 coupe with a 289 engine that has a 302 block.

this still doesn't solve the issue of it being a 2v, but it's an A code car.


how can i tell if the engine is origional in the car or not?

Your VIN contains the A code which was a 289 4V engine. 302's did not come out until 1968. If Ford had a 302 in 66' they certainly would have used it in a 67, but they didn't. The 67' Shelby even retained the 289.

C8 is a 1968 or later casting. That means the block was cast in 68' or later. It would take a pretty hefty time machine to bring back a block from 68' to install it in your 66' built car. Of course it is said that Lee Iococcia was ahead of his time. . . .

What you heard is backwards--in 68' Ford used both 289 and 302 engines, supposedly because of some shortage of 302 parts.

They did start to run out of 289 blocks in 66', but then Ford started pushing the 200 6 banger instead. During that time they created the special million Mustang aniversary promotion which were all 6 cylinders equipped and found in all 3 body styles.

The engine you have is not original, but parts of it might be (but it seems doubtful with the 2V and the wrong block.) The intake manifold and heads also have casting #'s, but you already know that the intake is wrong for your car. Checking all the casting #'s you can find that begin with a "C" should help you to determine what, if any, 66' parts still exist on your engine.

It looks like you have a 68 302 block and as far as 2v verses 4v that is an intake and carb swap. The replacement might have been a 2v or they did it for some other reason.

Actually, I think someone swapped in a whole 68 302 assembly, not caring that it was a 2v instead of a 4v.

These were just used cars at one time, and people did stuff like that.

I think it is pretty safe to say that if you have a 68 engine in your 66, it is not original.

you can also check the vin # stamped in the block right behind the rear intake manifold seal to see what kind of car it came out of

Just Google your casting numbers....

it's a 289 with a 302 block. it has a 289 crank, hence 1m stamped in the lifter valley.

it's pretty safe to say it's a 68

or perhaps it's just a bastardized rebuild . . block, intake & heads from different motors.
