Is anyone running this cam on their 347? I am wondering if anyone has the specs for this cam so i know what valve springs to get for my 180cc PTL's. I cant find specs anwhere. What valve springs are you runnin along with this cam?
Thanks, Mark

if you order the cam they will supply any valvesprings u may need for it. otherwise, stock lift valve springs will do, since its not one of their "HI REV" cams..

Thats way too small for a 347. I'd look into the N81 or N91. Sounds like your running mild heads, so the high rev cam wont peak that high. I have a 347 graph on my computer of the N91 hi rev cam, afr 185's and a holley intake and it peaked at 5800, 416hp.
