408 stroker rpm questions

That cam is ridiculous small and if you have the matches springs on the ridiculous small head, your getting what I would expect.

Your short comings are huge and it’s all the equipment that your using. Everything is to small.
Everything.

Carb, go to a 750
Intake, if it isn’t modified, modify it or swap to a RPM. Port the runners.
Cam; You can use a better cam with way more lift on better....
Heads; Smogger heads will perform like smogger heads unless you dump in $2500. Save money and step up to the new Trick Flow heads.

After all this spending, you’ll add a hundred hp and 1000 - 1500 rpm.
