This is a 427 making @ 550 flywheel hp where they are showing a longer primary tube 1/34 head making a very big difference in mid range torque vs a 1 7/8 setup.

Very little overlap (211/230 cam stock on 120 lsa) so would moving the evo or evc around at all in a setup like that even have any effect on crutching the loss if you were running a 1 7/8 header? Everyone likes to talk about reversion causing that dip... but if there was big reversion problems with stock cams they would be huge with the 240/255 115 lsa stuff people put in them but seem about the same. Is it all just pulse timing helping that one particular scavenge point?

I did a cam for one, smaller than most (mid 230s intake) and it seems to be on par for power with all the 242-246 duration stuff, but soft on torque compared to some of them odd for smaller with less overlap. The car has 2" primaries on it though, so I was thinking of moving the EVC point forward to reduce overlap and try and get some midrange back, thinking it wouldnt hurt top end power at all if its "overscavenging" now....but Im think its more a pure pulse timing thing in primary tube distance not a flow vs cam timing window deal
