Critique this combo - 318!

btw run the engine too cold and the bore go's away too, not from piston choice.

constant higher rpm's is what wears bores/rings [amongst other things] out as well, thats the only reason newer car engines/jap engines last as long as they do-light foot & Overdrives.

if you could keep the rpm's down yer old mopar would go over 300k
my 1500 4x4 is an example where with the overdrive/lock up it has 215k on it and go's down the freeway at speeds of 70-90mpg @19-2100rpm.
