I am just trying to find out if je b20b/z pistons will work with stock ls head.The block b18c has been bored and sleeved to 84mm.I also am using a ls crank,and ls rods.What kind of HP and what kind of comp ratio?

 

Sure they will work. Just check all your clearances. As far as compression goes, well that depends on alot of things. Same with HP.
Check out the dyno registry for an idea what you could or could not make. Too many factors and not enough info to tell you what HP and compression will be..

 

I am just wondering if anyone has done this same build.and i will list everything I have done.everything else is stock.B18C bored and sleeved to 84mm,stock ls crank,eagle ls rods,je B20B/Z pistons.stock LS head and cams.I plan on making it N/A.no NOS.guess my horse power and i dont know the compression of the pistons?
