That's just a bare block. Compression and cylinder pressure are controlled by the heads, cam, and the recipricating assembly. You can build just about any compression ratio you want.
The bore has almost no bearing on the compression. It's piston/stroke/head combo.yeah but without boring it, like i just put piston in without making a bigger hole or anything
Not much. The block just sits there. It's the combination of all the parts you put in it that determine the compression.so by boreing the block as nothing to really do with the compression ratio its just the piston cams ahead crank like your saying sry to repeat you guys but im just trying to get the facts right
