Thread: Help With My 360 Fe

Tweet

if im not mistaken the bore on a 360 is the same as the bore on a 390 just the strokes are diffrent. those pistions should work fine. its hard to say whhat your compression is going to be but i doubt it will be very high. why not use the 390 you have out of the galaxie

AND yes your 390 crank will fit in the 360 using the rods and pistons you have if you bought 390 pistons originally. I doubt that using the 360 crank will give you much compression because of the pin placement on the 390 pistons. Compression distance piston pin to top of piston: 360 (1.825) 390 (1.775) At least that's what my book lists.
