340ci vs 360ci engine

I agree with that statement.
The 340 makes more power and rev's quicker and has a higher upper rpm limit when in stock form over a 360 set up the same way in my opinion.
360's did not come with full bushed rods and steel cranks and good pistons in stock form and the 340's from 67 thru 71 did come this way.
even the 72 and 73 340's still have full floating pins and run fair on todays gas still.
I recommend the 360 though for they are more plentifull and if you hurt it then you are not ruining a 340 motor that could have been saved for a restoration.
Save the 340 for a true 340 car and restore it.
If you want a hot street car thats ok, .
The 340's are harder to find, But I bet you can get a 360 for next to nothing at a wrecking yard or ebay. Maybe even for free!
Be dollars ahead and be real about your expected performance level.
If you are not planning on reving the motor past 6,000 rpm then still stay with the 360.
Or if you want a go faster, or more rpm.. then chose the 340 or build a 360 using the full bushed rods and change to a steel crank instead of the cast. The dragonslayer is a great stroker crank in either application..
Built up a 340 still will outperform a 360 usually in my opinion, even in the stroker versions and full race.
Just my thoughts in print.
And I own a bunch of them 340's!

dont know how bushed rods makes an engine rev faster...weight of the pistons, rods and cranks usually determines how fast an engine can rev...called physics...

as far as reving a 360...never seen a stock cast crank 360 break...used to rev one 7500 rpm for two years... a bushed connecting rod broke..not the crank.

as far as making hp in the upper rpm...cylinder heads is what make hp...the short block is just pumping air thru them...

360 pistons are lighter then 340 in stock form...by over 100 gram...x 8 is 800 grams...which is almost 2 pounds...they use the same rods...and the 360 crank is lighter since it is cast..and balanced for a liter pistons...

in fact 360 pistons will always be lighter then a 340 due to the compression height of the pistons with the 360 having a longer stroke and both engines using the same deck height blocks.

take a 5 pound hammer and swing it...and take a 2 pound hammer and swing it....which one swings faster???? 2 pounds.....physics...
