My St Bob blew the motor.... So I'm going to do a SE stroker crankshaft...
I have pro st heads decked .040 with a .040 com. head gasket...
95", And 37 chain drive cams, Weisco 9-1 flat tops, CR 9.7-1..
What pistons do I need to keep the same CR..Thanks...Andre'

You'll need to either open up the heads chambers to add cc's or have a set of piston reveresed domed (similar to 883/1200 conversion pistons). The trick to the later will be getting a set of piston with enough dome material to accomadate the machining leaving enough dome thickness to prevent burn through when done. I would ask Axtell Sales for a possible piston. Another alternative is to stay with your combo but add a little more cam timing to work with the higher compression, this would give both higher tq and hp numbers with the right cam (this would be my choice).

Thanks for that...My St Bob is a little light for the And 37...Maybe a Wild Things TC4, SE204 or TW-44...
What would you recommend...Thanks ..........Andre'

Look at the Woods TW8 or T-man 590 with 10.2-10.5 compression. Valve to valve and spring clearances should be checked.
