how do i tell the which year the motor was made on a 318? is there anyway to tell? thanks trev

It should be cast into the side of the block (in code) Im sure Alex will fill you in better on this.

Guy is correct, it is cast like this: 6-21-68 this would be a June 26th 1968 motor, it is pretty easy to see cast into the area below the core plugz

Told you it was in code

:blah5:

I would have said it was made on June 21st 1968

If it is an Aussie block there will be a number stamped on a lug at the back by the bellhousing (just above the starter). For a 318 it will be prefixed with A221, then a letter denoting the year followed by the serial.

Thought I'd say because I have seen a few Aussie blocks cirulating in various cars.

Dumb question No.268 : do the 318/340/360 all start life as the same casting? also are there any 'heavy duty' or race castings and what would i look for if i was to build a blown smallblock, for example?

Nope. They are all different castings. For example the 340 has the same crank as the 318 but a 318 will not bore out to a 340.

The T/A block is the best. Try finding one though.

Didn't they make a 340 'X' block that was supposed to have all sorts of extra strength etc?

Yes James its the T/A block its a 4 bolt main block as Dave say's just try to find one rocking horse's come to mind.

They were cast to accept 4 bolt mains but they did not have them from the factory, as for finding them, see Pete ! he has 2, shame they are in proper T/A style cars !

I know where there is one But he's not selling

And at +60 with 3 liners you wouldn't want it either.....
