Re-grind cam or buy new?

I have a Lunati solid roller cam that cannot be identified i do know it has somewhere around 600 lift which is way too much lift for my 400 SBC Vortec head build.Do i send it to Lunati's cam doctor and have it identified for $20,(maybe i could use it with different heads)re-ground for $140 or do i buy another one?

Thats up to you. It also depends on if the cam has been a regrind before and if it has enuff base circle for the grind you want. On flat tappet cams the cost of a regrind usually is more than a comparable new cam. Roller cores are worth a bit more tho..

stir paint with it

A new smaller flat tappet cam won't cost much.

I dont know much about re grinding, but It seems to me that you would be greatly weakening the cam. I dont know. I agree that a hyd flat tappet would be a good bet. You can get a new cam and lifters for around $160 for comp stuff.

Had an old Econodragster years back. General Kinetics regrind on a steel Sig Erson core, .801 lift, The base circle was so small that when the thing was dyno'ed the rear lobes were 4-6 degrees behind the front, due to torsional twist, from the rollers and valve springs.. That was an expensive paint stirrer!!!
