Solid cam damage diagnosis help

Howards grinds those cams on CNC machines. There has to be a program loaded into that machine to grind Hughes cams. Maybe one setting was changed but why? Doesn't make any sense.

I have seen and heard about dozens of cams from virtually every grinder having an occasional issue with a mis-ground cam. And most grinders will take the cam back and make good with a replacement. I bought a Comp SBC cam for a C-30 tow vehicle I had years ago. It was ground 8 degrees retarded. No adjustable sprokets back then. It was a pooch. Sent it back and they sent a good one. **** happens.

I used to get free Engle cams from my sponsor. 351-C engines. No power off the corners but a sudden burst on top end. Broke my last freebie and called Chet Herbert. He laughed and told me I was running a Chevy grind that dosen't work on a Ford. Sent me a $39.00 regrind that kicked ***. The Comp cam was in their catalog!

I have run one Hughes cam... a 228 duration Magnum deal. Worked great. Biggest I could run with FI. OK service... no issues.

I have two new SBM cams on the shelf... a Mike Jones SFT and a Howards SFT. My lathe is sitting on my front lawn with a for sale sign on it... yard sale special. But I'll try to do some measuring tonite to see if ther is any issues between those two cams. Both are ground on a CWC core btw... I wonder who Hughes buys his SFT cores from. If it's CWC it will be cast into the core.
