340 pistons in a 360?

both engines share the same deck height...340 high compression piston has a compression height of 1.84...360 piston is 1.67.....you will have about .170 of piston sticking out of the deck...hitting the head....plus the skirt on the 340 piston must be machined to clear the 360 crank......

this was used with low compression pistons back in the early 70s went there were not many choices of 360 pistons...today there are many more choices of 360 pistons vs the 340....plus the low compression 340 piston still required the top of piston cut plus the skirt machining to clear the crank counterbalances.....a guy name Tom Hoover did a machine article on it...

the low compression 340 piston was used and has a compression height of 1.74..so the cut is not as much..but with the machining cost of cutting the piston and the clearing the skirt...buy the correct piston for the 360...
