S-10, all cam roller bearings I'm aware of are race only and aftermarket, you think GM ever put them in their OEM roller motors?

Did'nt say GM put them in as OEM. I was asking if he had a true roller that required the cam tunnel to be bored.

To begin with, set the timing curve up correctly. Info here.

Once the timing curve is set up right, see if the carb problem has gone away or is much better.

Knowing the cam specs will help. Short of pulling the cam or timing cover to get the numbers off the cam, you can find the specs close enough for tuning by following the info here.

Good luck.
