In '64, the 327 250 hp.had the #520 or the 896 heads, and the Rochester 4GC with the small intake manifold. The 300 horse 327 had the same short block, cam, and had #461 heads and the 459 intake with the AFB. The carb looks almost identical to the rear carb on a 409.In '65, the 327 250 was equipped with the #461 heads. It had the same smll intake, and a 4GC with a Powerglide, and a WCFB if a stick.The 300/327 had the 459 intake and the AFB.The L-79 327/350 engine came out then, and was an option in the Chevelle and the Nova. It would have been possible to order out a '65 2 door 300 series wagon with the 327/350 engine and a 4 speed. How many of those do you think were made?
