Is it the XE268H or the 268H . It's best to check it with a degree wheel . But if you do not want to buy one . Install it straight up . One thing to keep in mind . As a timing chain wear the cam will start to retard . This is one reson that guys advance there cams 2 to 4 deg . By advancing a big camshaft you will help on the lowed torque some times . But todays camshafts are much better then the one of the past . Most of the new camshafts that I have checked . were right Like the card said they should be . COOL

I ran the Comp Cams 262H in a '68 327. I ran it straight up and it was great. I'm currently running a 284H in it and run it 4 degrees advanced. I love this even more!
