XE256 in a 318 ?

The 7 1/4 will be fine with that combo. My '72 challenger came with a 7 1/4 and I beat it mercilessly and it never failed. One legger burnouts up a hill 100 yards long. In my '70 dart I don't have that cam but an old purple shaft that is .450 lift [email protected] duration in a stock '81 318 with performer 318/360 and big TQ off a 440. Runs real strong. Has home ported smog pump 318 heads and a four speed in front of a 7 1/4 for now.
