I have a 289 with low mileage compression is great cylinders are great burn no oil but needs crankshaft turned. I took the crankshaft out of the 289 and took it to have it turned they said (and I saw) that the front main would not beable to be turned. So they gave me a crankshaft from a 302. My question is Is this going to work?
I think the 302 has a 1/8 inch longer stroke then the 289. Is this going to mess up the upper part of the engine? Or is it going to be ok? Or should I find a 289 crankshaft and put it in.
Thanks
Brett

No, you cannot just swap cranks, due to the longer stroke. You would need 302 rods or pistons to make the swap. (I don't recall where Ford compensated for the extra stroke, though I would guess rods.) You should be OK with swapping in a different 289 crank. On the upside, if you can round up the 302 parts (should be very easy to find) you will gain 13 cubes.
