In need of an education..340 vs 360.

To the original poster. The EQ heads are better than the original heads, although leave much to be desired. Anything you can use on a 360 will work on the 340 excluding the crank and pistons, and the bushed rods. This I'm sure you're aware of. The drilled crank for the pilot doesn't mean it's a forged crank, you would need to look for a wide rib on the throws of the crank, and the drilled front and rear throws.
Unless you have your heart set on owning a 340, there is no good reason not to build your 360 for the street.
To the other 4 pages of useless pablum, I offer this. I build competition engines for a living. I am a member of the Society of Automotive Engineers, so I have the credentials to back up my statements.

A 360 with the same compression ratio and cylinder heads, cam, manifold etc will ALWAYS make more torque and horsepower than a 340. Don't believe me, Mopar rated the '72 340 at 10 hp less than the '74 360. Same compression, same cam specs, carburetor etc. NHRA rates the low compression 340 at less hp than the 360 4bbl. 360 Darts run on a quicker class index than the '72 340's do.
Small stroke engines don't rev faster. They have to rev higher to make power because they are just smaller air pumps. People gear them so that they can get into the useable RPM range sooner, but the engine by itself does not rev faster under load.
In building Stock, and Super Stock engines, one thing remains true. The 327 and 350 Chevy engines make more power in legal S/SS trim than the 340 and 360's. The heads simply flow much better than the horrible X and J castings.
340's are cool, I have owned a few '68 -'72's. but to build a small block Mopar I wouldn't hesitate to start with a 360. After all 273's also had forged cranks and floating pins and solid lifter and some even high compression, but nobody is raving about them beating up on 318's are they.
