Standard into 711m?

[johnny_h]

I got a standard 1600 engine with good crank that I want to swap into my 711m block. Is this possible? I see my fooked crank has 711mA stamped on it but the standard crank has 2737E on it.

am not engine builder but as long as its all 711m stuff then its fine,other to xflow type are 681f and 771m

[johnny_h]

That's what I am saying mate, it's not all 711m. the crank is from a standard cortina 1600 lump.

99% sure there is no difference, the difference was in the blocks, even the 618 rods and crank are the same

[oliwally]

there's a difference i think.

The main caps on the 711m are thicker where the 689f are thinner,that leads me to think the that the crank journals are wider or smaller depending on the block.

 

I do know of a short motor and complete engine that might be for sale

its not a 689f block its a 2737e the rods in johnny h's engine are 2737e rods as these are stronger than normal 711m rods so the caps must be the same width on the 711m & 2737e crank.

cheers Ian. they seem to measure up ok...

big end caps are the same,i know those are the rods to have in a big power xflow.

bearing main caps are different. look in the pic that the mains are different,might be same crank with larger thrust bearings to get same end float.

[johnny_h]

well it fits ok with the square caps and standard thrust washers....

Agree with that, I use 2737e rods in my 771m
