Too much cam



Really?

The 340 cam is a broomstick.

0.442" Exh. Valve Lift; 0.429" Int. Valve Lift; Hydraulic; (050) Duration at .050 Lobe Lift; 220 Exh.; 210 Int.; 114 Degrees Lobe Separation



At this altitude...most of you guys have no clue what a detriment 5000' is. A super hot 318 might run mid to high 15's up here.

Now a cheap fix for what's already there is advance the cam 4 degrees and go with the Rhoads V-Max lifters. Lose about 10 degrees of duration down low and that would really wake up what's there. Angle milling the heads for more compression would also help a ton.



Agree with how elevation can affect performance
