Camshaft Question

[New97owner]

Hey all, this has probably been posted here many times but I can't locate the answer anyplace with the search function here. I know the '96 and '97's had a different camshaft...can anyone tell me the lift/duration of the lumpy cams? Thanks all...
Mike

Exhaust duration = 305.0 deg
Exhaust lift = .541 inch
Exhaust valve head diameter = 1.575 - 1.585 inch

Intake closes 86.5 deg
Intake opens 23.5 deg
Intake duration = 297.0 deg
Intake lift = .541 inch

I wonder how accurate that chart is. According to the chart the cam is basically the same for all Gen IIs. The only difference is in the change in overlap in 2000. If that's true then why does the '96/'97 cams sound different?

My '98 has a very lumpy cam as well. The stats on the cam's year to year don't show it, but your ears do. My car idles so rough it scares small children and the elderly...

The overlap will effect how the car sounds. Competition Cams built their reputation 20 years ago on the 110 degree lobe centers, giving their cams a much more **** sound than their competition. 3-4 degrees can make a big dif in sound, and midrange torque, but at the sacrifice of idle quality and off-idle torque.

Same goes for my 98. Much lumpier than my 97. Dunno why.
