C16se v c14se

[nova1600]

Is the only difference between these two engines the bore size?
Is rods, crank and heads all interchangeable?
Can a C14se be bored to 1650 safely?

A 1.4 should be able to be bored out to 1650, as all the smallblocks are from the same/similar castings. You'd have to read up on the specs for the bore and stroke to know if the rods and crank are interchangeable. The heads are technically interchangable, but a 1600 head on a 1400 bottom end will cause a serious compression drop, and a 1400 head on a 1600 bottom end will cause too much compression.

Thanks for that. I'd mesure up cc'd in the head etc before I'd do anything to calculate compression ratio.

Any suggestions where I could find out if rods and crank are interchangable besides a haynes manual.

16se has a longer stroke than a 1400.

No way. Not by style. Just got offered a free c14se and wanted to see if I could make a 1650 out of it.

[nova1600]

16se has a longer stroke than a 1400.

How could the shells be the same size then for 1.3 1.4 and 1.6

[Stuart]

erm because they use the same big end sizes... but the stroke can be different

[nova1600]

So the cranks are the same but the rods are different in which case the pistons on the 1400 must have a thicker crown?
Is my assumption right?

[Adam]

I think the cranks different, rods are the same.
