W2 408 Dyno results today !

The sheet I posted is from 18 years ago, so the exact details are a bit fuzzy.
The cam was something like 262/266-108, using lobes that were easy on parts.
.630-ish with the 1.5HS rockers.

I will say that as it was on that sheet it had the 3450lb Challenger running 10.60’s.
The next year I put in bigger intake valves(2.055), and sold him a cam with a bit more aggressive lobes.
264/268-108 as I recall...... .645 lift if I’m remembering the lobe family correctly.
The short block got freshened, but not re-dyno tested.
The car picked up a couple tenths(10.40’s).

If you look at the air flow numbers on the sheet, you’ll see they level off after 6700, and the power starts to drop off a bit quicker from there up.
That’s the valve springs starting to lose control.
