Elgin makes good products. I put an Elgin Pro Stock cam in my car and couldn't be happier.
slayer, FWIW, I tested a set of 7/16 SBC 1.6 Scorpion "race series" Rollers back a few years ago (among others brands) trying to get max ave. for the EMC.
Part # SPN1003 came in at an actual ratio of 1.7 with test springs, and at 1.66 with full spring set-up. They gave me .057 thou extra lift vs 1.5 (static). Might have got some 1.65 and they etched them wrong at 1.6, or they just come over ratio'd, never got another set. But I would measure carefully in case.
NB: Sold them off as it only gave a + .3 TQ and +.6 HP sweep average, buddy has them on a healthy Mustang and runs 9.50 w/NOS and drives the car on the street all the time, in use 7-8 years now, no issues with them.
