422 dyno fail

I never said it’s stock....... and I specifically mentioned it’s 5ci bigger than the OP’s 422.
It’s a useful comparative tool if you’re open minded.

Headers or manifolds.... which is better?
Ported stock intake or aftermarket single plane?
Stock air filter(has to be in place) or not?
If you changed out those items on the Duster engine would it make more or less power?
And the heads on that particular engine flow less than the OP’s, so that’s not why that one makes good power.

Same can be said for the Stocker comparison.
It has less of everything than the OP’s combo other than cam duration.
Was less flow, way less lift, stock intake...... makes way more power.

When you race in classes where you have to stay within the rules....... you find ways to make power that don’t include being able to buy a bunch of the latest stuff out of the Summit catalog.

My friends stocker has been almost 129@3300lbs at an NHRA event(weighed and fuel check after every pass) with heads that flow 220.
he also has a 350 Pontiac engine for that car that’s been 123, with small valve heads that flow 200.
