That is classic, loved it I'll take a stab... Magnum lobe 3122B 289 236 160 .3800" XE lobe 3196B 287 236 162 .3910" .

LOL, Pontiacs don't need nitrous to run 10's. The poor guy's brain likely froze up when you told him you were running 3.08 gears...
So Chris, any future power upgrades planned for your engine? Where was Andy? Ernie, what exact tire do you run?

If interested here are reported flow numbers for a set of Dave Bisschop KRE D-port 82cc 300-305 CNC ported heads / 2.110 & 1.770 valves w/ 45 degree seats. Note, these numbers are from 2010 and they might be similar to Ernie's current '305' heads, but that would be a guess on my part. Numbers from one cylinder tested at 28 inches. No intake runner volume reported.
Intake: .100 74.7 .200 148.4 .300 211.4 .400 260.1 .500 290.4 .600 304.3 Exhaust: .100 68.5 .200 127.2 .300 167.1 .400 195.4 .500 218.9 .600 231.5 Average exhaust-to-intake flow ratio thru the lift curve is 78 percent. And my stab at the current exhaust lobe in use from the information within the link I posted, it's Magnum lobe 3123B with 246 at .050" and .4000" lobe lift. And the obvious, the intake cam specs I mentioned previously were the regular Old Faithful vs the revised OF 2.0 version. These lobe numbers are right from the Comp Mater Lobe Profile Catalog. .

One advantage to solid cams is the ability to tweak lash and let an engine tell you what it really wants. Without that feedback, 10 degrees extra .050 duration on the exhaust seems to be a common default. |

5800 or so..it may like 6000 to 6200

"5800 or so..it may like 6000 to 6200"
If it helps, proven dyno numbers for a similar combo. But 4 degrees less intake duration. 455 .030 over 4.250 stroke KRE 300/305 d-ports CNC port matched torker II / HP950 carb 246 degree hydraulic roller / 112 LS 593-600 ft.lbs. Tq / 4600-4700 (peak) 589 hp at 5800 rpm (peak) .

And the lifts and durations were metric?

About 0.016764 meters gross valve lift with his Harland Sharp rockers
0.660" Works very well the heads that will continue to flow past 0.600" lift. .

I guess its time to finally install my shiftlight..since my factory tach only goes to 6000rpm.

Ouch, I just noticed a BIG mistake I made in conjunction with the combo mentioned in my post #54. The cam used had 10 degrees more intake duration than the OF 2.0 here ! Obvious mistake as I stated it had 4 degrees less. It made peak power at 5800 rpm with a 246 degree hydraulic roller cam. I should also point out It used solid roller lifters which would have a tendency to raise the peak rpm a bit.
Sorry for the confusion. Here was testing by Dave previously with less cylinder head and the 'regular' OF cam, from his web site.... " We decided to do some intake manifold comparison testing on a 474ci engine running a set of our 290cfm CNC ported KRE D-port heads with 10.2 to 1 compression on 91 octane fuel with a 236/245 duration hyd. roller cam. Torker II has a square bore plenum so we installed a 950HP Holley on top of it with a 1" open spacer for the last test. The Torker II didn't disappoint and produced 554hp @ 5500rpm and 584 lb ft m. @ 4500 rpm. " .
