Slightly strange head flow question.
Maybe this will help
XS282S Cam - .520/.540 lift @ .50, 244/252 @ .50 duration, recommended 2500-6500 rpm
If I have access to two two pairs of identical Edelbrocks (springs valves etc)
- one set flows 260cfm at .550, the other 290cfm at .650,
For arguments sake, lets say both display "healthy" low-mid lift figures also.
Which should I use and why?
Assume the cam, M1 SP, 800cfm carb and everyting else will not be changed.
