Hey there sled heads, first timer here with a question about an old,1976 according to the ownership, rv340 free air. This thing has been altered for the track. I'm rebuilding the engine and found not stock or anything close to stock pistons in the old girl. I think someone was cheating. The cylinders are 73 mm,10 mm over standard bore of 63. The cc calculator I found on line says its a 452 cc motor. My question is what the heck would the stock motor have been? Assuming its been bored to within an inch of its life? Thanks, klark
