Torino Mike

I (think) have a 71 429 torino cobra with C8VE-E heads and the number 064 stamped in the front of the block near the coil.

Is this a 429 or 460 engine?

I haven't had a chance to look underneath yet.

Thanks,
Mike

heads are interchangable. Go under the car and tell me the casting on it.

Would've come with the 429 stock. Could have been changed since then. You'll need to know which crank is in there to know if it's a 429 or 460. 3.85" stroke (1.92" between the throw and crank pin) and you have a 460.
