Re: 1967 Chevelle SS 396 375HP?
 

I can't speak for a 67's but if it were a 69 L78 car, one of the "clues" would be a single fuel line.

The car has KK code 4:10 posi. Will the fuel line tell me anything? What date code and plant would narrow the possibility down. Is it since the L78 option was dropped from the line-up would 67 L78s be an early build? Like an 11E build date and Baltimore plant?
Thanks for all the responses.

L78 was cancelled in the Chevelle at the beginning of 67 production and re-released in April of 1967. The earliest cowl tag date I am aware of in a documented real car (without a fishy deck stamp or other red flags) is 04C.

No way to absolutely confirm the original HP in a 67 with it's engine gone and no docs. There are numerous tell-tale signs of an L78, but the problem is they can all be bolted on the car from another car (such as a hi-redline blinker tach, deep groove pulleys, a 67 Z28 fan blade and clutch, etc.). And some of the items were also available as options with a 350 HP 396 (such as a 4-row radiator with fan shroud).

I have owned 2 - 1967 Chevelles with the "360" horsepower engine. Both were P.O.P. documented, L-35 / 1 - M-20, 1 - TH400 / both 3:55 Posi, both had an Iron intake & single feed Holley carb, both had hydraulic lifters and were rated @ 360 horsepower on the factory open element air cleaner sticker.

The L-34 was a Rochester 4 Barrel Iron intake, hydraulic lifter, closed element air cleaner, and rated @ 325 horsepower., The L-78 was rated @ 375 horsepower, had an aluminum intake, open air cleaner element & dual feed Holley carb, and was solid lifter engine.

The first car I had was in 1973. What I remembered:, there were 2 hydraulic lifter engines available in 1967, a 325 & a 360 horsepower rated engine, and 1 - 375 horsepower solid lifter engine. Could be a case of "Sometimers" setting in....if I'm wrong.

-----Hey Bill,,,Im trying to get a handle on what you are saying, as I wasnt aware of 1967 "360hp" Chevelles being delivered. 67s were available with 325, 350, and at various times during the year 375s in my occasionally flawed memory. I cant say I have ever heard of a 67 "360hp", but that could be MY "sometimers" https://www.yenko.net/ubbthreads/imag...mlins/hmmm.gif. I looked at a bunch of 67s new on the dealer floor in the fall of 66 at various dealers but never saw a 360 hp 67!!! On the other hand I never saw a 375hp 67 Chevelle on the dealer floor either, but I did see a few during the year in the first owners hands.
-----You are certainly correct about the single fuel line on all big block Chevelles built in 1967, however.......Bill S

67 had the 350 HP motor. Also, I think the L-35 was 325 HP. L-34 was 350 HP.

Re: 1967 Chevelle SS 396 375HP?
 

Bill & Mark,

I just looked in a 1967 Chevrolet Dealers album I have, and I was incorrect. I had L-34 & L-35 reversed, and there appears to be no listing for a 360 horsepower in 1967, only in 1966.

I know the second car I had was a first week of November 1966 build date and it had "360" horsepower sticker on the original chrome open air cleaner lid. It could have been a 1966 left over sticker.

The first car I had was in high school in 1973, and we never had a clue about trim tags, build dates, ect. Sorry for the "Sometimers" moment.

Don't forget about the L79 327/325hp (350hp) that was available in 1967 but not 1966 in the Chevelle line up. It was a rare bird too, as was the L78, and by most standards a serious 2nd option to compete with the L78 for perfomance rights for Chevelle.
