Disclosure: This site may receive compensation from some link clicks and purchases.

Do you have a ’65 or ’66 Chevelle SS that’s missing it’s big block and Muncie transmission? Or maybe you’d just like to upgrade your classic with a 396? If you said yes to either of those, this barn find might be of interest to you! It’s a complete Chevy big block with a Muncie mounted to it. No word on which version of the 396 it is, but the seller provides photos of all the engine numbers, so that should reveal which engine this is. Find it here on eBay in Chattanooga, Tennessee with bidding to $1,375. So do you have a car that could use this engine?

    Wow! I am in Chattanooga. No car body to put it in, but would be tempting just to have it in case one day…

    Only big block chevelle in ’65 was a Z-16….and it’s engine code is IX….and had an aluminum intake with the big valve heads….this is a lower horsepower engine…probably ’66 or if a ’65 date code, an impala engine….

    IAR code is 1966 396/325 with manual transmission for a passenger car. I put a Corvette 3×2 intake on one one time and it screamed with no other mods.

      Good find Jon, I just got through looking through some ID books I have as well. that code was a passenger car or SS Impala with 4 speed. Maybe the guy thinks it’ll bring higher dollars if he says it’s a Chevelle. I have a close friend with a 66 Impala with the 396/325 and 4 speed. Great car, he bought it new. red with black interior, he says the car salesman talked him into that motor instead of the 327 that he was wanting at that time and now he’s glad he got the big block. He recently gave it to his son and they are halfway done with a complete resto on it. I like your three deuce set up. looks like it belongs there.

    Are you sure it hasn’t been sitting in 3 inches of water?
    Can you run the numbers on the block and find the car it goes in?

      It looks like it was in 3 FEET of water or perhaps it came out of a dirt track race car!

    “have a car?” …… Well yes, I have a late model Corvair coupe. :-) 396 would settle in nicely. Actually, the most quick & violent car I ever drove was a Crown conversion Corvair that was beautifully engineered and had a circle track race engine in it. Brutal acceleration.
    Another bit of trivia: Did you know that the autocross Fastest-time-of-Day at the 2015 Knoxville CORSA (Corvair) convention was taken by a 427 mid-engined Corvair with Powerglide? The course was not “Mickey Mouse”, but was also not a big wide open layout. Surprised me………

    A big block won’t break a corvair?
    Send Ralph Nader a video.
    Tell him thanks for nothing.

    I had 325 horse 396 in a 1965 Impala 2 door hardtop with a bench seat, posi-traction and a 4 speed. I also had a 63 Corvair Spyder and remember the Crown Corvair conversion advertisements in Hot Rod magazine very well. I always thought they looked interesting. A big block humming a few inches from your back in a Corvair would be a thrill indeed.
