Cam buttons ???
OK I'm going to pull out the original motor 89 Formula 350 (180K+miles). I've rebuilt what I've figured was a L31 short block. Basically the stock equivalent Howards cam and everything else OEM. Did the original L98's have/require a cam button? I haven't sealed up the oil pan or timing cover yet.
I did the timing chain on the original motor about 5k miles ago and there was not one in there.

Re: Cam buttons ???
I thought so but there was so much mis information out there. The cam plate holds it where it needs to be right?

Re: Cam buttons ???
Flat tappet cam = no extra cam retainer needed
Factory roller cam and block = cam retainer plate (block is casted/machined and tapped for plate to fit)
Retro fit roller cam in a non roller block = Cam button. (no place on the non roller blocks to bolt the cam retainer plate, so they use a button between timing gear/cam and timing cover to keep cam from walking forward in block)
Factory roller cam and block = cam retainer plate (block is casted/machined and tapped for plate to fit)
Retro fit roller cam in a non roller block = Cam button. (no place on the non roller blocks to bolt the cam retainer plate, so they use a button between timing gear/cam and timing cover to keep cam from walking forward in block)
