the biggist issue i see with herberts cams are the lack of choices...lol..
but i digess..
its got a fair bit of duration..it might bleed off too much compression..
depending on what your starting with mechanically for compression..
however...it seems there are those out there running someone elses camshaft with them.
my issue/concern is if you dont use a herbert cam...you want to make sure the cam lobe base circle doesent push or seat the lifter up so high that it exposes the oil passage..and you loose oil pressure. when it comes to ordering a non herbert cam.
so knowing the dimensions..the cams base circle needs to be at..might prevent a mistake..

i am very anxious to employee them..i just need to get the best data..
id hate to tear down a perfeclty good running race car..only to have to spend a ton on machine work....work and $$ i dont have time for right now...
but if its a plug and play...then i am in sooner than i would hope to be...

any one with experience can chime in ..
