Hello I am new to the forum. I sure Hope someone can identify these Chevelles . I have asked this question to a lot of Chevelle
Owners,forums,and even Chevrolet Heritage Site and no one knows about them.In the spring of 1966, I went with a friend to a
local Chevrolet dealer to purchase a new Chevelle.(Charlotte N.C.). Not finding a car he liked out front we went around back and
Saw 1966 Chevelle SS. This car was a 396hp with four speed. The Decal on the air cleaner was a factory decal with crossed
Flags just like the rest of the 396's,but this one had Factory Experimental 375 Horsepower on the Decal.The car had a 4:56 rear
gear. About 25yrs ago I read in a Corvette magazine that in 1966 Chevrolet took the 396 425hp. From the 1965 Corvette upped
the horsepower and put them in these Chevelles. The article said that they rated the horsepower in the 4,000 rpm range to get
375 HP..They didn't want the Corvette owners to know that the Chevelle had the same or more HP. Than the Corvette. PLEASE
Don't tell me that the Chevelle had a 375hp. Option in 1966. I have seen several of these and these are not the ones I am talking
About. I keeped the Corvette mag. But I think I lost it.

thanks for any help

Here's more info, it was a 65 Chevelle not a 66, the car was called a Z16, the engine was a custom built hydraulic lifter engine an L37 engine. Current value in restored form is around $150,000.00. They came with factory tinted windows and a remote drivers mirror, gee wow.

There were no production cars from the factory that said "experimental".

The 425 hp 396 was called an L78, they also made a 427 425 hp engine called an L72 in 66 and an L88 in 67. The L88 could be ordered with aluminum heads. They made an aluminum block 427ci 425hp eng in 69 and stuffed them in a Camaro called a Z11. Its times in the 1/4 mile were strangely slower than the iron 427 425 hp.

Around 30 years ago, I bought a very clean, all orig factory 396ci 425hp, 4 speed, bucket seat, 66 Impala, for $6500.00. I sold if for $8500.00 bucks 4 weeks later. I made around 32% profit on the deal, pretty good huh? I have never heard nor seen of another since other than that they might have made just a few. Probably worth a bit more than $8500.00 today, lol.

Barrett just sold a 67 aluminum head L88 427 Vette to a guy I know for around 3 million bucks.

ha.  i just looked at a 396 sitting in a guys shed the other day.   its just down the road from me.  been sitting there for over a year.   not sure what he wants for it, as i'm having a hard time catching up with him.   i ran the block casting number and it came back as a 66-67, 2-bolt, 396.   i dont know if its worth messing with or not?   kinda small for a big block.    somebody said all 396's came with steel cranks.  anybody know if that's true?    i know it's for sale, just not sure how much.  its complete, carb to pan with a set of rusty headers laying next to it.

well if its a std bore, give him 200.00, toss the heads in the trash, put 4 bolt mains, afr heads and build it to 400 hp or so. that stupid eng will spin 7500 rpm, lol.

the crank is cast iron, buy a forged one for $350.00

Thanks for the information guys, I mean no disrespect, I know that you all know way more than I do about Chevells.This was
a new 1966 Chevelle SS. 396 4spd. With 4:56 gear. I drove this car many times,it was super fast.(I actualy got lockup for
for Reckless driving at the age of 19). The sticker on the Crome air cleaner was a factory sticker just like the other 396's withFactory Experimental 375 Horsepower on it. this was not a an add on sticker. this is the reason that I suggested my friend buy it. I think
That the magazine article said that there were 100 of these Chevelles produced.  Are there still a Corvette Magizine,maybe I
Should get in touch with them and see if they would still have a 25yr old article

thanks

ok

please get back to us and let us know. i'm very curious.

i hope you get your answer and without too much brutalization by them, they are not always the friendliest group, lol.

there were occasionally cars called "mules" before chev came out with the C.O.P.O cars in 69. These were special order cars that dealers requested with engines that did not come in them but none of those had any special experimental nomenclature on them.

Thanks shyrgfuh,I E-mailed Kevin Suydam at the second site you listed with the same post that I listed here. H e said that everything I said was correct ,except he has never seen the word experimental on any air cleaner sticker. He said that that engine was in a few 1966 Chevelles and a few 1967 Chevelles.Still hope to find information on air cleaner sticker. I will keep you posted if I find anything further.

thanks

hi

thanks for gettin back, i saw your post over on yenko, you got lucky, they were nice, lol.

what engine are you saying is correct?

a 396 with more than 425 hp?

a 427 with 450 hp instead of 435 hp?

you might be misinterpreting what he said or possibly he didn't understand his question.

it is astronomically unlikely they would build a 396 with more than 425hp for any reason at all. it simply defies all logic. besides that, it would be nearly impossible to do without tube type headers.

in addition, the gov was cracking down on high hp supercars in 65 so the mfg's agreed not to produce cars with more than 425hp. the l72 427 was actually 450hp but they slapped 425 hp stickers on them and rated the hp at 5600 instead of 5800 rpm to get around the 425 hp limit.

i also worked at a major vehicle mfg as well and they would never put anything that said "experimental" on a production vehicle simply for liability purposes.

say someone got in a wreck with the car and their lawyer say the word "experimental" on the body or engine etc. hes gping to sue the mfg claiming that since it said "experimental" it proves it was not proven safe for the general public, he wins, the mfg looses.

i'm surprised kevin got back to you so quickly. he's a bazillionaire and doesn't need to waste his time on people like us, lol.

Shyrgfuh70,
It was the 396 425 L78 engine that they lowered the rpm rating to get 375 HP..Kevin Suydam did say that he had never heard of an air cleaner sticker with he word experimental on it. It's possible that it could have had F/X on it.Maybe I should just let it alone until I can get more information on this car. The Chevrolet Dealership that the car was sold at is now out of business,and Chevrolet Heritage said that Chevrolet only keep records back until 1977.  Unless I get the vin# for the car or actualy find the car I guess I may never know. thanks to everyone for being so patient

thanks very much
ronnie

"It was the 396 425 L78 engine that they lowered the rpm rating to get 375 HP."

LOL, BZZZ, Nope, wrong answer again. It is what I said it is, which is the L72 for 1966. Read the article in the link below.

I may not know everything about these but i do happen to know a lot. There's just no reason for me to hang out at the Yenko site but one might wonder how i knew about it and Kevin Suydam, hmmm.

Also, they cannot lower the hp rating of an engine they never made!

You came here for answers, we were happy to give them. You said we were wrong. I sent you to other sources and they said the same thing we did which I knew they would. Now you are still trying to tell me I'm wrong. I posted the proof that I'm right in the link below. Please post the proof that you are right. It can't be done because no such thing ever happened.

The only other person you could ask is Dick Gulstrand in Calif, he ran the high perf dept of Dana Chevrolet back in the 60's and was a chev sponsored champion vette driver.

If you never heard of Dana Chevy, they are the first people to put a 427 in a Camaro in 1967. A Dana car is worth two or 3 of the other high perf dealer/builders like Nikkey, Baldwin Motion and Yenko etc. Dana was also a dealer for the Yenko stingers.

Suydam has a mint all orig custom color 68 Dana camaro. There are few to no other known Dana cars in existence.

I don't know how to help you any further.

Shyrgfuh,
sorry about the L-78 engine code ! I think I got that from an answer to one of my question I didn't remember the engine code.I apologize if I caused any hard feelings. Maybe I should just stick with the type of cars I know more about. Thanks for taking the time to talk with me.
