Question for L6 gurus;

Considering some mods to my L28N42, current set up is internally stock ie dished pistons, rods, bore, etc.

Reading through a couple of books last night and was thinking rather than fitting flat top pistons, would it be worthwhile fitting L24 rods to the L28 crank, effectively giving a total cranking length of 212mm (top of stroke), as opposed to standard 209mm. Just considering this as doing something different, but don't want to create hassles by doing so as well!

L28 crank has a stroke of 79mm, rods 130mm.

L24 crank has a stroke of 73mm, rods 133mm.

My combo would obviously be stroke L28-79mm, L24-133mm rods, 86mm bore.

Anyone done this, and if so, thoughts appreciated. Can it be done with flat tops, or would comp ratio be too much? Would the pistons protrude too much past the deck? etc etc

Thanks.

it would not change the length of your stroke but change where it takes place in the cylinder, giving you higher compression. One thing to check is piston/ valve clearance.

Yes, correction, doesn't change the stroke, but the overall rod/stroke length.

I also would like ot know if there are any problems with this setup?

I was actually having a play with the L series engine calculator last week and found the L24 rods would give me quite nice compression in my L28.
