1968 340 Cam Choice (Again)

I agree...my xe 268 did have some valve train noise but i grew to like it.
I should say it's not all that bad in town.
My car is a daily driver, so about 95 %
Of my driving is in town 45 mph max.
The valve train noise is tolerable
But on the Freeway at 3500 rpm @ 70 mph
It's annoying, to me anyways.
I've thought about using some dynamat or something on the firewall to quiet the sound inside the car..
