Anyone know if the KB pistons that one would buy for a 1911 (stock 1.8L con rod) are different than what one would buy for a 2.0L con rod? Is the wrist pin height diff? Just wondering if I need to exchange the pistons I now have.
Also, what is the consensus on what cam and size of carbs? Thanks. |

isn't the pin SIZE different as well? 24mm vs 22? or is it just the height? even if you replace your pistons the 96mm cylinders you have now could work.
IIRC, isn't an 86b a mid-high end cam? we went with a 163 webcam great low-end torque and pulls good all the way up (IMG:style_emoticons/default/smile.gif) very nice for street, imo. FWIW, we used AA pistons with the valve relief. just my .02, but if you have a 1911 now? why go to a 2056? not a big jump for a good chunk of change.. if your 1911 needs a new cam, you can do that... or you can look into 2200(76x96) or 2270 for not much more.

Stock 66/71mm cranks use 24mm pins, strokers typically use the 22mm pin to allow the pin to be closer to the crown, keeping the engine from growing too wide, and to use Type 1 rods. |

If you have 22mm you can get a machine shop to bush your rods to size. might cost you $200-400. Type 1 rods don't fit a a type 4 crank. Welded stroker cranks have extra material welded to them so they can cut it to the type 1 (or chevy/buick) rod size. |
