Wiped Out Cam - Was: Drag Strip Results



I used Rotella the last time I changed oil. The previous was regular oil with Comp Cams Break-in Oil additive when I installed and broke in the cam. I did a little around town driving, one trip of 100 miles to Norwalk Dragway, and one run down the strip. The motor had been running for a few years since the last rebuild. I just changed cams. Died about the time I was on that trip to the strip.

I no longer trust Rotella.  Better to be safe than sorry.

I now am using Valvoline VR-1 (?) racing oil with a ZDDP additive. So far, I've put about 125 miles on the engine plus 8 or 9 blast down the strip with 5500-5700 RPM shift points.

Don, was the wiped out cam a flat tappet or a roller? And what type of oil were you using? Any ZDDP additive? There sure is a lot of debate about these newer oils and additives..............................MO

Took the Belvedere to the drags for the first time this year. I've did an engine rebuild after wiping out two cam lobes. Went to a .545 lift Camp Cam

shaft.

Performance was okay with a best of 12.5 and 107mph. Best 60 foot was 1.80. Funny thing is that the last 1/8 mile was pretty consistent at 4.6 seconds for runs from 12.95 to 12.50 - didn't matter. Still got a way to go to get to sub 12
second run or even beat my personal best of 12.40 at 110.

One problem still there is that it seems to run out of gas over 5000 rpm in first gear. I can run second gear to 5700 and going through the traps at 5300 showed not fuel starvation. Work around was to shift to 2nd at 5000 and to third at 5500/5700. I don't have a fuel pressure gauge but it seemed to stutter pretty bad so that's my guess. Have I called it right? Might be too lean or an ignition problem although the latter seems unlikely given the 5700 rpm shifts
later in the run.
