This is getting off the Push Rod subject but I an't resist camshaft discussions as I may make a change for more high end performance.
I am satisfied with my Isky E-2 cam which has lasted over 24 years in my 3400 pound 40 Chevy coupe w/ a mildly modified GMC 302. Mods include: Areas 9:1 pistons, large valves, ported and polished big port head, HEI , 3 Weber 32/38 carbs, dual headers and 1 3/4 exhaust w/cutouts, A/C, a T-5 5 speed and Ford 9 in. 4:11 rear. The E-2 cam specs are shown above in my earlier post. For on the street driving the E-2 works great. It idles smoothly but is noisy due to the .o18 tappet lash and will pull the car along back roads at 1000 rpm and 27 mph in 5th. It cruises well on the freeway too going 65 at 2400 rpm. Drag Strip Performance has varied.My average is 14 .2 seconds and 85 mph. My best with a good tail wind was 15.86 and 88.9 mph. If my mild engine were in a <2000 lb car, 1/4 mile averages would be 15 sec. and mid 90 mph ranges. The only reason I might change cams is I would like to break into the 90 mph and 15 sec range consistently. But I am now 76 and have Parkinson's disease, so I might have to be happy with what I have.
