Stock for stock never seen a 302 beat a 340. My 383 road runner beat my friend 68z easily. My 340 see's 7000+ all the time. Stock bottom end with forged pistons.
With no drilling of the oil passages or other work done?
Lucky you as I see most every guy try this and cry later on the engines oiling failure. 7K or even north of 6600 I would not ever try again without paying some attention to the system. I paid tuition that way once and only once when I was young and dumb.
