Thanks for the info, just started taking 1999 donor block apart, original owner said approx. 95,000 miles before Durango rusted out on him. Cylinder walls look very good, with great original crosshatch. I calculated, pistons above deck .008. Good to hear yours were at/near deck height. Option 1...
Saw your info and was thinking about using KB107 4.000 pistons in a donor 99 dodge 360 magnum for my 99 Dakota rt. Just checked #1 stock piston and it is .044 below deck height. What r ur thoughts on using the KB107, seems to me they will be above my deck height a fair amount...........
