HYD ROLLER CAM Regrinds

I bought a Hughes regrind years ago and it was 214/216 w .510 valve lift. - worked great.

This ebay seller has regrinds w 228* @ 0.050” w 1.5 rocker .525” valve lift -

I was just wondering how much can you regrind a cam?
Regrinding a stock cam,
You don’t have a lot to work with.

Have you called Ken at Oregon Cams? He'll tell you how far you can go on a regrind. When I spoke to him several years ago, he said he couldn't go as far as I needed at the time and I was looking for something in the 230* @ 0.050", .550" lift range.

There are too many variables for you to get an answer off the internet. Give him a call at get it straight from the horses mouth.
