I had a 340 in my 1970 Cuda. All my paychecks went into that engine and it would run high 11's. What an engine!

A lot of early 1968 340's had the thicker rocker arms contacting the edges of the larger diameter valve spring retainers. The service bulletin called for the dealer to grind a clearance in the existing rocking arms.

Your right the 340 is AWESOME!! I like to think the 340 is a small block that thinks it's a big block.

"It's not all loose and floppy". Unlike my belly from a career of drinking beer.

Regarding the tick. You said some of the lifters you can't push down. I had some that became stuck and took on apart to find bearing material. So do have a look at the bearings for groves. Now things you can't live without. A deep pan for the 340. A edelbrock straight ram intake for the 273. And not to harp on this but the 2x4s intake for the charger and its wakey wakey for that motor.😂

You need a poly 318 aka “Semi hemi” thats a engine that not many people know or talk about. Another thing i love about Chrysler is when they came out with the 340 TA From the factory it is ready for you to put a 4 bolt main if you wanted to. I’m a die hard 440 guy but after building my first 416 (340) i was even more impressed.

👍Good stuff! That 360 looks great & is dressed perfectly!

Someone has already mentioned the poly 318. Not many aftermarket parts but it's very possible to make a beast of an engine out of it and they sound amazing!

340 is no joke my older brother has a 69 dodge charger with a 340 not factory of course, and I have 70 roadrunner with a 383 mild cam and the 340 will walk all over it. The RPMs are ridiculous on a 340.

CHICKENS 🐔 Epic video as always jamie.

Great Video 👍 can't wait for more on the cuda ! I'm told the j heads are the ones I Should Want ! Mine has the X , and of course it leaves a huge oil mess everywhere 😂

Ya know a vid on smallblock heads would be cool. Large valve "J",small valve "J" and "X" heads make my head ache.

340's were known for taking down the " legendary " L79 327 on many occasions .

I would always take a 340 over a 383 like when it was offered in the later RR's. Actually, the stock performance was about the same but the car with a 340 was more well balanced, nimble and better handling. With the short stroke the 383 is more like a 'big' small block and won't rev as quick or high as a 340. The small block head design (OE) is better too.

That's the exact same way my 318 keeps leaking in the swinger, somehow, just somehow, I keep missing a microscopic spot in the rear corner and it leaks enough to make me cry in similar fashion

I remember taking my 383 out of my charger when I decided to restore the car. My friend and I decided it needed rebuilding because it had a ticking. It sound like it was coming from the back left of the engine. When we took the engine out we found out it was the flywheel sprocket hitting the dust cover underneath. It sounded so much like it was coming from the top lol 😝 duh!

Years ago i had a light weight rotating assembly, 13 to 1 440 with indy heads and dominator. That would rev like a worked 340, Turned over 7k through the lights.

I keep hearing a ticking as well. Mine goes away when I start the engine :-) Maybe the Demon just needs it's heart back.

If a 340 is built right and not overheated too badly or over revved too many times, it'll last a long time. I built mine in 96, drive it at least monthly, I don't baby it and she's still going good. I drove it across the country in 99 just for good measure. 26 in 2 core Radiator, 11 to comp. Solid cam. My friends think it's a freak of nature.

I agree with a careful examination of the lifters.
