We have the KBs in my kids 360.They work well with 10.2 compression.Rocky




+2, if these are the KBs i'm thinking they are, its been awhile sence i built my .060" 360, i think they were KB192s if my memory serves me, they were a quench dome pistom, my compression was 10.35.1, ran great on pump gas with the XE284H cam, RPM air-gap, 750dp, stock J heads, this was by far the best street SB i owned, it was a screamer, at 3700ft. alt., it ran 13.2s @ 104 in a full bodied 73 Swinger & 4.56 gears, that was on the limiter in all gears too (6000 chip), car was low 12s @ sea level easy, so these pistons will work on pump gas & iron heads.
