Go ahead and swap it out, put it in @ 102-103 c/l put tighter lash that what the card says, I run 12 intake 14 exhaust , 410 will run fine on the street and the track, be nice if you could find some 430, as for the rpms would not be scared to go up to 7 tho thru the traps but you will go @ 6300-6500 with what you got? power glide killing ya ,, unless your in a super light car!! good luck
