Even if that had happened, the chances of getting two different sized wrist pins from like engines is rare. The Vulcan and 4.6 proabably will have different wrist pins.Ĭlick to expand.Are you asking if the wrist pins are different per piston or per rod from the SAME engine? That would usually be no, unless someone has swapped out one or the other from another engine. The SHO 3.0 and 3.2 have different wrist pins. The wrist pins are different from engine type. If you want to use stock rods thats fine.

I would not use the pistons unless the rest of the geometry has been verifed. The diameter may be different diameter which may be good BUT you need to make sure the rest of the geometery is the same. You are going to have issues using different pistons period. I'm not boosting it, so I don't need the strength.Īaand are the wrist pins different per piston, or per connecting rod? I just need to know if I'm going to have issues putting the 4.6 pistons onto whatever rods I find to fit the bill. The change in bore will bring the displacement up a staggering 5 cubic inches, but the selection of pistons for mustang engines makes it worthwhile.Īnd I don't want forged because the added inertia won't do me any favors for N/A. I'm getting my block sonic tested, and if the machinist ok's it, it's getting a 0.052-over bore to fit the 4.6 pistons. Vulcan pistons have a diameter of 3.50 inches, where 4.6 pistons have a diameter of 3.552. Sure you can find connecting rods for $30 but are they forged?Ĥ.6 pistons aren't the same as 3.0 pistons. Why are you using 4.6 pistons? Unless they are an exact match to 3.0 pistons I wouldn't bother.

In fact they are even different from the SHO 3.0 and 3.2. Click to expand.No not all wrist pins are the same.
