Looking for a good small block to run in my 72 Scamp. I found a 1969 318 out of a Charger and a 1981 360 4bbl out of a motor home. Both run good and are about the same price. Which would I be better off with? I know the 318 is going to have better compression being a 60's model. But does anyone think the 360 is a better choice? Thanks

Yes I am dropping them in as is. I plan on getting the /6 to V8 conversion mounts from Schumacher and no I don't have a pan for the 360 yet. I guess what I'm trying to determine is which engine bone stock is going to give me the most power. Thanks for your help.

For about the same price I don't see much of a question. 360 all the way. The slightly higher compression of the earlier 318 vs the torque of the 360's stroke and additional 42ci, is a no brainer to me.

The 360 comes with a working transmission and the motor is complete from top to bottom. Still has a/c compressor and power steering pump attached. It's actually a little cheaper than the 318 too. Torque is definitely what I'm looking for so I might just look into getting the 360. Any tips for some cheap horsepower?

360, for the reasons mentioned above, plus, it will have hardened valve seats for unleaded gas.
It's Swifty! Swifty, you toad sucker!

Excellent point on the hardened seats!
I don't know A bodies so well, but I am not sure a motor home 727 will bold right in, especially if it is like a normal truck loadflight vs car torqueflight. It would be trade or resell material though.
By the B&M 360 to 904 weighted flexplate and run a 904 behind it. The 904 uses less horsepower to operate so more ends up at the rear wheel. For stock pistons etc, a smaller cam like an edelbrock performer with matched valve springs will give you the best performance.

replace the low stall TC from the 360/MH trans to a stock high stall TC weighted for the 360 external balance.
thats the biggest improvement for bone stock 318 or 360 engine. IMHO.
then the regular bolt ons like carb/intake/headers/rear gears make a fun A-body

a short shaft 727 with bolt on yoke will bolt in and work if you build the drive shaft with spline/slip yoke. (I had a 76 short shaft 727 in my 68 Dart also my 88 440 truck with a BB short shaft)

Sounds like the 360 is the way to go. I think it will give the most bang for the buck. Plus it is more complete and with a little work it will make a fun driver out of that Scamp. Thank you all for your input! You've been very helpful!

Use the 904.
As for the engine choice, as much as i'm on a small-engine big-efficiency kick, for what MOST people want, the 360 is the obvious choice. A Charger is just too heavy for a 318 anyways.
Better choice would be to continue shopping around and find a 5.9L 360 Magnum, and do that swap instead. Better mileage, way more power, hell... many different little bonuses overall. I just bumped a pretty informative thread about it.

if you want more power, go 360...if you want mileage, go with the 318....
for the 360, replace the cam with a lunati voodoo 60401 and valve springs with the comp #901's
if you want "free hp" run a 904 based 998 tranny--it has the lower gear set (2.74 first and 1.54 second, instead of 2.45/1.45) and it takes about 1/2 to 1/3 the power to spin than a 727.
