Justin,

I'm in the same boat going from a 261/268 @.050 and .585/.570 on 107 in at 105 mild roller to a 260/269 @.050 with .668/645 lift on 108 in at 106.

The heads (airwolfs) are "advertised' to flow 301 at .500 and ~314 at .650 so I should have been leaving airflow on the table with the old "Endurance" roller. I'm also at least 10 degrees at .200 "hotter" than the old cam.

I'm doing a big converter swap at the same time so I'm not sure how much I'll be able to tell....but I'm about a week out from the converter swap, I'd like to try to get a couple baseline passes on just the cam.



What is more important or makes more power, the duration @ .050 or the lift? My cam in my small block has less duration @ .050 but has more lift than Streetwize.



Both are critical and need to be matched to your cylinder head flow specs and your static compression ratio to optimize your engine combination. Rate of lift is also very important and seems to be often overlooked.
