Re-read the cam per 360duster's recommendation, making sure to keep my caliper at 90 degrees to the lobe, the results were sickening actually - sending this cam back, I think the guy at the grinder was high :homework:
The cam was supposed to be .525 intake lift and .512 exhaust lift at 1.6, which by my calculations means .330 and .320 respectively at the lobe. Here is what I measured working from the front of the shaft to the rear, each lobe in it's respective position.
#1 EXH .310 x 1.6 = .496
#2 EXH .314 x 1.6 = .502
#1 INT .307 x 1.6 = .491
#2 INT .305 x 1.6 = .488
-----------------------------
#3 INT .310 x 1.6 = .496
#4 INT .307 x 1.6 = .491
#3 EXH .309 x 1.6 = .494
#4 EXH .308 x 1.6 = .493
-----------------------------
#5 EXH .312 x 1.6 = .499
#6 EXH .308 x 1.6 = .493
#5 INT .306 x 1.6 = .489
#6 INT .306 x 1.6 = .489
----------------------------
#7 INT .305 x 1.6 = .488
#8 INT .311 x 1.6 = .497
#7 EXH .312 x 1.6 = .499
#8 EXH .318 x 1.6 = .509
The bigger problem, not that this isn't bad enough, is the inconsistencies in the base circles.
#1 EXH base circle measured 1.245
#2 EXH base circle measured 1.241
#1 INT base circle measured 1.236
#2 INT base circle measured 1.240
-----------------------------
#3 INT base circle measured 1.242
#4 INT base circle measured 1.242
#3 EXH base circle measured 1.237
#4 EXH base circle measured 1.251
-----------------------------
#5 EXH base circle measured 1.238
#6 EXH base circle measured 1.251
#5 INT base circle measured 1.253
#6 INT base circle measured 1.249
----------------------------
#7 INT base circle measured 1.247
#8 INT base circle measured 1.243
#7 EXH base circle measured 1.243
#8 EXH base circle measured 1.236
With pedestal rockers, not adjustable, I would need different length pushrods for each lobe to maintain proper lifter preload/lash.
With things being this inconsistent on the lift alone, I'm afraid to look at duration - sending the cam back as soon as the call tag arrives.
