Intake - #797 Valve lift .410 (10.410 mm), Duration Adv 297°, Duration @.040 (1 mm) 259°
Exhaust - #1043 Valve lift .400 (10.160 mm), Duration Adv 300°, Duration @.040 (1 mm) 250°

Once the cams arrive, the bucket cradles will be machined for clearance. And then the head goes back to Loynings to have the seats machined, and check the valves for valve to valve interference.........

much more to come.......

Along with big valves... you get BIG CAMS



Here is a photo comparing the new 797 Web camshaft to the stock cam :eek:



How much larger....?????

stock



THIS much LARGER!!!



As you can plainly see, the bucket cradles will need to be machined a bit so these camshafts can turn in their bores :eek:



Got a quick quiz question for the viewers....

Why does the Web 797 camshaft (total duration 297)



Look more like the HKS 264 below, and looks like less duration then the 272 in the photo below????
