It would be interesting to dyno an engine with manifolds and keep swapping cams till you found the best one, then dyno the same engine with headers swapping cams till you found the best one....How far off would the best numbers for each be?




It really depends on the whole package. The milder the engine the less the difference. Just remember all these fancy Hemi's today still have manifolds. For the price they are the best option.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
