Actually someone told me its got 140hp carbs on it and bubble back exhaust on it But the hood says 115 so I dont know what it is and I dont know the year. That's what I'm mainly trying to figure out is year and if its a 115 with upgrades or if its a 140 with 115 decals, i think its 90 degrees cross flow. The cylinders are off set one bank is higher then opposite bank.
