i was doing some looking and found that online fourms show 64-66 326 2v had 1.88 intake and 1.60 exhaust and a 8.6 cp. rated at 250 horsepower however 67 shows 9.2 cp and 1.92 intake and 1.64 still the 250 horse engine. side note being the 6 was the same has 67 not the 64-65, i found this out in my phs papers that show the 66 had the same specks has the 67. anyway what im wondering is did they lye bout the horsepower being 25o in 64-65? was that higher then what it was or was the 66-67 a low rateing? i mean they bumped the cp up and added larger valves and i think the 2v on all of the above was a large one like 400-500 cfm, can it really be power didint change at all?
