Can I put a 1300 crank with pistons into a 1100 Xflow engine - then add the 1300 cylinder head to make a 1300 engine. I have a combination of good and broken engines, any advice would help

Block and I believe head are identical , crank will fit as well as 1300 pistons but probably not worth fitting used pistons IMHO . Double check main and big ed bearings aren't oversized on the outer diameter as Ford's sometimes used them to salvage blocks even from new

You'd need 1300 rods, as the 1100 had longer rods.

Interesting
I thought blocks were longer
I only know the smaller engines had thicker pistons so you could increase compression by putting 1300 pistons in a 1600
Turbosports forum is the place to ask, it may be that your 1300 crank will foul the 1100 block

Thanks Folks. I'll try it out next rainy day and report here. I'm new, could someone tell me where about on here I could find a bottom end 1600 XFlow for sale?

1100 / 1300 share the same block (ending AA)...thats why people selling a 1300 engine just by giving the casting code (ending AA) is not a 100% gurantee that its a real 1300 engine.

please compare the pistons, as you may be lucky increasing compression by using the orginal 1100 pistons in your new "1300".....
