So im building a 512 stroker and decided to go with a roller cam seeing as nobody seems to be able to make a hydraulic flat tappet cam last anymore. What a fringin night mare. I knew very little about roller cams and what was involved in making one work. what is with this stupid cam button? i got one from 440 source and it was way too long. so we took 100 thou off of it. not sure if it was too much or not yet. Then i bolt the timing chain on with arp bolts and the bolts hit the cover! So we took the washers off and it seems to clear now. we discovered the difference is the one with the torrington bearing sticks out farther....[censored]. anyone else run into this problem? this is supposed to be the way to go? been nothing but a nightmare trying to figure this out. anyone run into this before and how did you deal with it? like i said this roller cam stuff is all new to me.
