All three have very competitive HP rating and are Excellent!
It comes down to your personal preference.

And your bank account. A competitive SS 383 should run about $35,000.

I think all the above combos cost about that...... the 340 might be slightly
cheaper. The protrans and the heads are a bit less from my experience
for the small block but not a ton cheaper.

I'm a big fan of the Super Stock 383 combo. It's got a good factor (300 hp) and enough carb for the cubes. Don Little, Steve Wann, Mike Cotten, and others have run very well with it.

The 440 is fast as well. Not very many 340's out there. I'm sure there's a good reason for that. Head CC's maybe?

Jared: The 340 around 280 in SS last time I looked........It is 293 in stock
and still Fast.

The carb is same size Carter on 340 and 383 as I recall.

NHRA changed spec on X heads a while back to 167 after a bunch
of fighting which is a decent number for small block mopar heads.

The main reason I run the stock legal engine in Super Stock rather than
a ever build a real SS engine is that is very difficult to find a cylinder head
builder for SS out west. My friends that do my stock stuff are not very
interested. I left a set at a well know Head Place and he left them on the
Shelf for two years.

When I run the 340 Stocker in SS......it run slightly under to SS index and
and I think it would sure pick up in SS trim.

I agree that all three are good combinations!

Jared: I hope you Legendary Grandfather is doing well
He has always been a Hero of mine since the 1960s!!

I still think you should go with a 383 in that. I see a hunk of scrap metal sitting behind the Dart.

I forgot about the 318 only using a stock type 2 bbl carb even in SS.....I am in the process of building a Magnum 318 and didn't think about that....

Paul, a .030 over 318 is 323 cubes, a .070 over with the off-set ground crank is around 331 cubes........

I also agree with the 383 combo.....

Yea, I was thinking .030 over. Shame on me for typing before turning my brain on.
