would anyone know or ever tried fitting a jp racing piston and sleeve & crankshaft into an rb concept rody x12??? i cracked open my jp racing rs-12 last sunday and i have a bnew spare rb engine block... i'm trying to look for a jp engine block or just the regular novarossi rs-12 block but luck seems to hide from me. they look the same but i'm worried the timing might change. pls help. PM me if anyone would know if it would fit.
