Not that fat, Brent knows I have the old c3az-k grind that came with the 8v 427 cars. They've come a long way in 45 years, so I would understand if he didn't want to take a "step back in time." Here's the specs of the K cam off of a Cam Doctor machine (not my machine). Basically it's 245/.525 at .050 -- 324 seat to seat. I have it installed 5 degrees advanced for an ICL of 109. It has a nice following over on the FE forum, but it's admittedly old technology.

Oye vey is right! For a guy that sets FTD only running to the haberdasher that's an amazing amount of tech for a .508/.509 'cool-sounding' cam.

OK back to Brent's build-so Brent, how many roll hoops you gonna need-six? eight? Better buy a bunch of hole saws...

I posted it because I know my ol' pal Jerry would enjoy seeing it. And I'm sure he did.
