Like everyone else, Here's my plan on a rebuilt for A100 van.

Strong stock rebuild with a 225, .30 over if needed.
Standard/stock Bottom end with Doc's oiling mods and whatever other neat tricks he printed that I can't think of off hand.
Erson's RV-15 cam, Stock rockers and such.
Full Ported head with the BIG valves on both side, hardened seats too.
Head milled .50-.70 Haven't decided yet how much. Looking for a 9.?-1 comp
Blocked milled maybe 10-20 for clean up and lower deck height.
S.S. with a Weber DGV, 727 stock tranny
3:55 rear.
Stock gasket matched exhaust manifold w/2-1/4" tubes and turbo muffler.
I just want a stronger than stock build outta this. If I can get 175 horses with this I will be happy. The thing is what is a good Piston that will put me in this window that will give good grunt for a van? I pretty much have everything else for this build but need this info. Any ideas? Thanks

For your build the stock type cast pistons will be fine.
Frank

I take you just mean the Mopar off the shelf replacement like ths one?

All the slant six engines use the same piston. The standard bore size piston is PN 2084384. There are four oversize pistons available in the sizes of .005, .020, .040, and .060. The piston pin is a press-fit in the rod and has a diameter of .9008".

Summit has cast replacements for $11.69/ea. several sizes

here

those summit pistons are good the federal mogul or power seal are the same they go to .080 over for slantsix`s and the design has the metal insert remove and thicker pin support and skirts all aluminum.

Any of these will work fine.

Ted- That's pretty much what Im lookin to do minus the elec. fan, ram air, carb deflector, and Im going to run Pertronix instead.
ANYBODY know anything about this place or think of the price??? http://www.mecanicapedrosa.com/6817.html

have you looked at the piston and rod combo from k1 and wiseco? You'll be at a higher compression (10/1) and the piston sizes are not your norm. They are using metric pistons so tis like.025, .045 and so on.....this may only be good for you if the block hasn't been machined yet.

they are reasonable in there pricing and lighter that stock rods/pistons.
