he 4.0 rods are longer. that combined with the longer stroke of the 4.6 crank would result in:no694terry said:i thought a 4.6 was just a longer stroked 4.0, so im my thinking if you used 4.0 rods on a 4.6 crank with 4.6 pistons you would have like 4:1 compression

I currently am running this set-up (4.6 crank & rods with 4.0 pistons) and have done so for the last few years. I have a 96 GEMs disco running 4.6 crank 4.6 rods with 4.0 pistons installed on the 4.6 rods. You gain compression up to about 10.9 : 1. I am also running a 4.6 cam and using my old 4.0 heads, intake etc.KyleT said:whats the advantage or reason to run 4.6 rods and crank with 4.0 pistons? are they the same? i have seen a few references to this lately....
