340 or 360

First I want to thank you all. Great replies.
I have two 360's and one 318 all 74 or newer. I saw an ad for a 340 block for 200.00 and a friend said he might have heads still for a 340 in his garage, thats why the debate. My car is a 74 dodge dart sport 318.
And I'm putting togather the 360 as I learn. I'm gonna get a Christmas card from summit this year for sure :wink: . The 360 that runs is in a 79 crysler cordoba it pulls real strong for a big car. Rated between 150 and 170 hp ??? I dont believe it for a minute.

Also is a 9 1/4 rear any good??? I put 355 gears and a new carrier housing in the rear of the cordoba but will it hold up to real power??

Once again thank you all.
