340 vs 360

[PartsGuy]

Ok i am to the point that im going to pull the 318 out of my 74duster. I wanted to get your thoughts on wich motor can perform the best with only like cam intake and headers. Hopefully this dosnt start a war lol.

if you are on a budget it's easy... Get a 360. 340s are at a premium and that is reflected in the cost.

I can get a 340 long block with steal crank for 1300.00 havnt priced 360 yet. As my handle intells i have been an the auto perts biz for 8yrs its a good place to find freinds with hard to find stuff luckaly.

360 is cheaper to find than the 340. Cost is about the same to build one or the other. 360 will build more torque than the 340, 340 might climb in RPM faster, but thats a general statement, either can be built to suit. If you are going for the most hp, a 360 will always have 20 cid advantage. Also, if most cid is the game, an early 360 block will give you more cid after all is said and done.

360...more choice in pistons are lower cost, rings are less expensive since they share 4.00 bore ...

360 is alot lighter then 340...rev faster...

I like the 360's torque and not having to make it twist like crazy to get power, however I like the 340's hp numbers and the fact that it's possible to find one with stock 10.5:1CR. I have a 360 in my duster that is very mild and it's a little suprising at times. I've been in 340 cars that were slightly built and watched people shift at 8000+ rpms, my 360 wouldn;t dream of that. But as it's been said in this thread, anything can be built to suit, I'd probably go with a 360 for cost effectiveness.

Advantages of the 340, smaller main bearing crank journal (less friction) , internally ballanced, and coolness factor. Advantages of the 360, more cubes, longer stroke (more torque), more piston options, cheaper block.

360s will be cheaper, but really, don't get a mass rebuilder engine. Long, short, or otherwise. They are total trash in parts and labor, not to mention questionable repair practices. There are plenty of rebuilders who are not an Auto Tek, or Jasper, or Target type place. A 340 long block for $1300 is frightening me...
