Hey guys, I got a hell of a deal on a 2001 LS1 with 68,000 miles. I pulled the heads, oil pan, front cover and cam to inspect it. I was told it was a blower cam but unsure. Any help would be great. I have a Thumpr Cam that I was planning on swapping over from my truck but would like to compare it to this one first.
Numbers stamped in on the cam
RRSI 221G-221(cuts of the next number)
U77D
114
241 160

I measured an intake and exhaust lobe and got roughly .575 and .585 calculated using 1.7 LS1 rockers

Had a cam kinda like that a long time ago. Might have been a tsp cam if i remember correctly. Just like is says on the cam 221 221@ .050 on a 114

I took a chance and called Lunati to see if they could help. They found the numbers in their system and said it was a custom grind they did.
.580/.580 lift 221@.050 with 114 LSA.
Thanks for the help, I will be selling this cam as I think my cam will be better with my setup
