I'll try to make this short and sweet: I talked to John @ Delta yesterday, gave me the specs for the F22a 272 cam: 371/371 lift and 201/201 duration @ 0.050. From other sources, on here and on F22parts I've seen specs like 409/409 lift and 272/272 duration thrown around! On several occasions on here, I've seen posts that label the 272 cam having a 272 duration. Which specs are correct? 201 duration sounds pretty weak, did John give me stock specs?
I couldn't even find the stock a1/a4 or a6 cam specs on here, they were on here, but I read only 1 comment about the stock cam being somewhere around 350 lift and 200 duration; almost the specs of the 272 from Delta. Am I misinformed somehow?
I just seem to be getting all sorts of numbers for the Delta regrinds, not just the 272, the 260/282 also. So much mixed information I've been reading.
