I've modified an R/C car, the 2.0L in my neon, and the 170 in my Barracuda in some way or another...lol.
I thought it was what would you want to start with....lol
360 or 318 which would you rather have???

As it has been said it is a loaded question. Not enough information on what you have planned for it.
400hp or less I would go with a 318 anything more stick with the 360.
Also depends on, if it's a get a round town car 360, or highway cruiser 318.

340 T/A would be my choice but then again I am from the era were a 318 is a grocery getter engine and a 360 was a smog motor.

I'd rather have the 16 cylinder Chrysler Hemi used in the XP-47 Thunderbolt before it went to a radial engine. google it. best mopar engine ever. I'm surprised that wasn't a poll option.

Since my car already has a 318 in it , that's what I'll build-up . Why should I pay the extra coin to buy another motor ( albeit , they are inexpensive ) ? Then , there are other expenses to consider :
- New motor mount / bracket ( and I'm talking about a good setup , not those shitty Chinese ones that break if you sneeze ! )
- 727 Trans ( durability . Certainly a 904 would 'work' , but no matter how you build it , it won't be durable like a 727 . Yes , I'm talking daily driver status here . )
And , I'm more in favour of a 340 any day . Superior motor to the 360 ( doesn't make the 360 bad by any means ; I just like seeing a 340 in a '68 - '73 car , even if I couldn't tell the difference just by looking at it ! ).

Well, I have a very mild 360 in my Dart right now. 360hp/380tq per a conservative Desktop Dyno build. It's almost a waste because a 360 is capable of so much more, but the block came with the car and it was already machined and ready to put together.
On the other hand, I have since acquired a good 318 with a set of 302 heads that could easily be built into a nice sub-400hp engine if the 360 ever let loose.
What is really bad is that I have a NIB 3.55" MP stroker crank to build a 346. However, the extra cost to build a 346 just isn't worth it when considering my target HP. :read2:

Where did you hear that? A properly built 904 would be fine.
Yep, built right, a 904 is a damn fine transmission. Lighter, and take less power to operate.
I haven't voted because I like all mopar small blocks. They all are good engines. I would love to max out a stock bore/stock stroke 318 just to see what it could make. Maybe I'm a little biased towards 318's because my father has always liked them...

I beilevce, not a 100% sure, but close to it, that XP-47 was after WWII. That engine held the speed record for piston drive aircraft for a year or two. The radial engine was used from inception.
Ha ha ha ha :spiderma:
Hey, nothing lotto can't fix! WTH!
The question is wide open without description. Just simply stated. Answer as is. Which would you modify. Period. I voted with you.

360 cuz it has a longer stroke and can out-torque the 318 no matter what. Also parts (i.e. pistons) are actually cheaper for some reason, look at the price of a set of KB pistons for a 360 they're actually cheaper than the 318 ones. Something to do with the 360 pistons being smaller (wider too) maybe? 318ers are 1.81 CH while the 360s are 1.675 or so to achieve the same deck height. The longer stroke makes the piston thinner and cheaper. I think it all depends on your budget and what you expect from your engine. I'm doing much research and am trying to get the most power and efficiency out of a small displacement, kind of a science experiment of sorts.

They both have their place.
If I was chasing outright performance it would have to be a 360.
The 72 Dart Swinger I'm doing is to be generally a daily driver so by choice I've pieced together a 318 which I think will go abt 280hp(abt what I want)

and 1/4 minority like the 318, aint that the way its always been?

Two "XP-47Hs" were built. They were major reworkings of existing razorback P-47Ds to accommodate a Chrysler XI-2220-11 water-cooled inline 16-cylinder inverted vee engine. Really big inline engines didn't prove to be a good idea in general, and the XP-47H went nowhere.

I have quite a menagerie of books, I'm reading a book on airflow by Harold Bettes, it's an HP series book. I have other ones on various subjects as well, porting is one. 30 mins? Where are you located?

thats becouse the USAAF (United States Army AirForce) decided against
using a decent 2-stage supercharger. they stuck with the single stage version.
and on the contrary, the Bf 109F/G/K's were inline engines, there rate of
climb and level flight speed where among the fastest in WWII. faster then
the P-47 razorback & bubble top. also the P-51D Mustang using another
inline ( the Packard-Merlin) was a 400+mph ride. the fastest fighters in
Europe were mostly inline engines. granted there were other fast radial
engine WarBirds, the Fw 190 & the F4U Corsair for example.

They did not use it because it was not as good of a motor as the Pratt & Whitney R-2800 that was already in the P-47. But then the R-2800 did have a turbosupercharger on it:toothy10: I do like that motor. It was an inverted V16.
The XP-47J was the fast P-47. It had a wicked up R-2800 and a cleaned up airframe. It did over 500MPH. The Hemi powered XP-47H could only do a little over 400MPH.
