Re: 2.8 3.1 stroker ????
As stated any 3.1 crank can be used, RWD or FWD, same goes for the 3.4 crank, since it is the samed as the 3.1 crank. Both use the 3.31" stroke.
All 660 rod used from '82 to '04 are the same, all are forged steel all are same dimentionaly. After '04 the same rod was still used, but particular engines, like the 3500 and 3900 had a different crank used, with larger rod pins, and I beleive a length change which makes these ones impossible to use, so it's easier just to say "up to '04".
The pistons must be from an iron head application, when using iron heads, other wise the static compression ratio will be in the toilet, if aluminium head pistons are used with the iron heads. Around 7.0:1. The iron heads have a chamber size of 56cc, the aluminium heads use a chamber size of 28cc, quite the difference.
Your best bet, if you can't get a complete iron head 3.1 is to use the FWD crank and get some aftermarket stock replacement pistons, for the iron head 3.1.
