These were designed/custom built for use in a 3L block with a 3L offset grind crank using 4G63 Rods (Mitsubishi) / rod bearings. The pin diameter was custom spec'd @ .866 specifically for a Mitsu 4G63 rod making these "plug and play" with the rods.
The engine specs for the pistons were as follows:
Deck Height 9.03 (stock 9.05)
Bore 4.125
Stroke 3.622 (92mm) = (deck clearance .043 @ 8.01:1 compression) - (you could take this to 93mm with deck clearance .024 @ 8.35:1)
Rod Length 5.9
Chamber Volume (61cc - this varies but what my actual 2.7 8V head measured)
Gasket thickness 0.40 (again this varies and can be raised/lowered depending on what you desire for compression / etc.)
Piston dome -34cc
Pin Height 1.276
You will need to buy JE 4.125 rings and .866 pins to install (*not included*), let me know if you have any questions, thanks!
