I've been looking around and I can't find anything specific enough to cover what I've been trying to figure out. I'm planning a b18c1 build and I want to use the skunk2 pro 3 cams. So in that case if I were to use an LS crank and rods with pr3 pistons @ 82mm would the valves hit the piston or is the valve pockets on the pr3's great enough to clear.
And also I've read the issues with an LS crank in a GSR block with the oil squirters but I've also read that the rods will hit the bottom of the cylinder wall. If I'm at 82mm would that still be a problem or would that have been eliminated due to bore.

82mm on stock sleeves? good luck with that.

pro3's are really big cams. pr3 and pr3 "style" pistons dont have very big valve reliefs to begin with. you want to be sure, you clay the thing and check your own clearances. i have to ask, why use such big cams and limit it to a stock piston?

how much actual research have you done? your questions are only bringing up more questions.

those pistons are completely wrong for pro3's.

bore size has nothing to do with the crank getting in the way of the squirters.

The bore I hadn't read much about. I was considering resleeving but I didn't really plan on turbo so I didn't know if that would be cost appropriate. I've been trying to read around a lot before posting but I felt I had no where else to look. I thought the pr3 would serve the best compression while hopefully still clearing the valves. And I wasn't concrete on the pro 3. Pro 2 maybe if that would clear I wouldn't have a problem with that, maybe I'm on the wrong train of thought?

I know the bore has nothing to do with the squirters that wasn't what I meant. I meant would the ls rods hit the bottom of the cylinder walls. Or would a little have to machined off to clear.
