Took this out and need to sell so I can move on in life
... $275 + shipping
These are the specs. straight off the Cam Doctor. If you want more, I can scan the whole printout for you. Degree values @ .006", .050" and .200" given so you can figure out the lobes.
LSA = 108.3
Valve overlap = 31.7 (crank degrees)
Intake:
Duration @ .006" = 308
Duration @ .050" = 246.8
Duration @ .200" = 155
Max Cam lift = .33984" (~ .577" with 1.7 rockers)
Exhaust:
Duration @ .006" = 312.3
Duration @ .050" = 252.3
Duration @ .200" = 160.4
Max Cam lift = .3402" (~ .578" with 1.7 rockers)
I have all the info about valve openings, lobe centers, lobe area, etc. but to keep this simple, presented the most popular measurements.
So it all boils down to : 247/252 .577/.578 108lsa

Researched it a little bit after I was told what it was spec'd and it's very close to a T-Rex Killer cam (but has a bit more duration). I was also told it's more suited for a 400+ cu.in. engine (108 lsa is too much for my 6.0ltr and it needs to be rev'd real high to get anything) with a single plane/carb. style setup (Thanks Pat G.) but this cam "was" in a friend's 347 that did go 10.40's with a high stall ... so it all depends on your setup.
Here's a vid of it running.

UP UP ... $200
A little bit more info. This cam with a 6.0ltr, TH350, 3500 stall and 3.42's (and the LS2 intake was choking it) went 11.26@120 taking off really easy to save the 10bolt ... with a better breathing intake and a higher stall this would've been an easy low 10sec. ride but I gave up due to financial constraints with drag racing and went with a street setup (M6)
