stunter01 Posted February 16, 2018 Report Share Posted February 16, 2018 Hi guys I'm building a new engine with 4mill stroker crank longrods I got pistons with the sleeves wsm 68 mill think they are specially made for stroker crank My question is , do you get domes for this set up. Oh i forgot to say i got a pro design coolhead . The piston edge are about 2mm out of the sleeve at tdc Quote Link to comment Share on other sites More sharing options...
Toybreaker Posted February 16, 2018 Report Share Posted February 16, 2018 you need cylinder base spacers (worst idea), get domes to match the stroke/piston combo(decent solution), get the right pistons so you can just assemble it (easiest solution) take the sleeves and pistons back and buy a set of driveline assasin lp or hp cylinders and domes (best solution) Quote Link to comment Share on other sites More sharing options...
stunter01 Posted February 16, 2018 Author Report Share Posted February 16, 2018 I would love to do that, the problem is in south africa you can't buy it off the shelf There is not really shops that import the stuff they only keep the basic parts Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted February 17, 2018 Report Share Posted February 17, 2018 You'll need to measure the deck height, and know your piston part number. Call or email a shop willing to ship to you. Fast, Noss, etc... Give them the deck height (how high the edge of the crown sits above the cylinder at TDC.) Then make sure they know what piston you're running and they can set up the domes to fit the profile of the WSM pistons which are a little different then typical Weisco options. My old short track motors were big bore stock cylinder set ups, so let me know if you have any other questions. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted February 17, 2018 Report Share Posted February 17, 2018 68 mm wsm pistons have a banshee crown. I have some measurements written down at home I'll check it out later Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted February 17, 2018 Report Share Posted February 17, 2018 I recall the WSM big bore stuff was 12* not 13*. Does the 1* even make much of a difference? Quote Link to comment Share on other sites More sharing options...
