I am bidding on a 289 block it is a C40E6015C unit that is describes as

The 221, 260, 289 were originally designed for the Fairlane and produced only in the Cleveland engine plant from 1962-1965. The 1964 289 casting number for all 289s was C4OE-6015-C (later an F suffix). In 1965, this number was changed to C5AE-6015-E for the 289 2V, 4V and Hi-Po (note the change to full size Ford designation and 6 bolt bell housings).
In mid-year 1966 the Windsor plant also began producing 289s. The casting numbers for these were (C6AE-6015-C with a "289" and "WF" in the lifter valley. In 1967 both Cleveland and Windsor produced 289s using earlier year casting numbers but with updated date codes. These two blocks were interchangeable, but there were probably some minor differences. Near the end of the 1967 production run, Cleveland ran out of 289 blocks and substituted their new 302 block, C8-OE-6015-A and marked with 302 in the lifter valleys. This block wasn't intended to see action until 1968.

The question I have is this engine compatible with the Tiger 260 that is a windsor unit?

Yes, the 289 engine will fit as the block is basically identical with the obvious bore difference.

Yes, the casting number is for a early 5-bolt 289.
It will replace the 260 without any other change.

Thanks for the advise, I bought it and it seems to have very little wear, will wait till I get time to do a full measurement.

Sounds great, hopefully it has not been tinkered with too much and the bores are also near original. Very hard to find un-molested quality blocks these days.
