i did a 74 351 stroker with a roller cam retro fit and it did take a fair amount of work that i was not aware of , ie. grinding a flat place for the dog bones to rest .If they are not flat they will wear and get caught on the lifter.also it takes a special size push rod. drill and tap the bolts for the spider and do the grinding before you boil out the block to avoid chips of metal in the wrong places .so far mine sounds and runs great ,less than 1000 miles. Good luck.
