1100 and 1300 Crank

Recommended Posts

I've just taken an 1100 engine out of my escort, for more power. 1300 fitted but not quite running. I know the 1100 and 1300 block are the same - but have a different crank shaft, to give more throw of the pistons. My question is - are the connecting rods the same on the 1100 and 1300, or are the 1300 longer? I can get a 1300 crank shaft for £100 so was hoping to make a 1300 out of a 1100. (I have a spare 1300 cylinder head) any help would be apreciated

I think 1100 would be 4.85mm longer than 1300 rods. 

The stroke differences are-
1100cc - 53.29mm
1300cc - 62.99mm

Therefore, 62.99 - 53.29 = 9.7

9.7 ÷ 2 = 4.85
