HT or HP Suffix Code?

[Nick Dillon]

A friend just bought a 66 coupe s/n 12,xxx with L79, M21, N40, J50, and others but no a/c. It is well documented with dealer contract, POP and list of all previous owners. The VIN derivitive matches and the engine code is F0I04HT. The Black Book shows HT as 350hp, m/t and HP as 350hp, m/t, p/s. Chevrolet by the numbers shows HT to be 350 hp, m/t with hi lift cam and HP to be 350hp, m/t, hi lift cam, a/c, p/s. All the documentation points to the car being legit although I realize it could be forged. What is the correct suffix code for this car?

Re: HT or HP Suffix Code?

Both sources you quote say the same about HT suffix code and that agrees with NCRS '66 Judging Guide (327, L79, 4-Spd). The HP suffix you quote from the Black Book disagrees with the NCRS '66 JG book. The NCRS JG book agrees with Chevy By The Numbers (327, L79, PS, and A/C). Suggests there's a typo (omission) in the Black Book regarding C60 air conditioning....
