HF = 350 2bbl, powerglide, 250 HP L65 engine option. Should be a 2 bolt main block with a nodular iron crank.

The A149, & A169 mean that the heads were cast 2 days apart... January 14th & 16th 1969. Your heads are 441 castings, 76cc - 1.94/1.50 valves.

Everything seems to jive with what the car is suppised to be.
