The info on the cams (i quoted the wrong lift) Lift = .420 at cam,
duration 288 degree advertised 248 degree at .050. Base circles Exh =
110 degree Intake = 106 degree.

128 hp @ rear wheels @6200 (128 @ rear wheels = 150.5 @flywheel)
118 lbs @ rear wheels @ 5200, 100 lbs from 3000 - 6400, 110 lbs from
4000 - 5800. (118 @ rear wheels = 138.8 @ flywheel)

If we ever get a scanner I could post some Dyno sheets. You wouldn't
beleave some of the changes. 4-5 each by cutting 4 inches off my
collector pipe. 4 each w/o air box. Can't run w/o one here in Fla
(sand). But do have a K&N filter charger on end of stock flex pipe.
Really need to build a custom air box.

The same bottom end but with stock Sprint head and cams was 106.3hp
@5900 & 101.9 lbs @5000 both at rear wheels.

Spring, bronze guides, valves all from Dave Bean (Ken) I can supply
exact part #'s if you want them.

Hope this is useful info.
