Does my 451 have to small of a cam?

Your talk is fancy but your missing the whole point, He has ALOT more issues going on & to think a carb change will be his miracle cure is nuts, he needs to fix his main problems 1st...

...his MPH to be so low at 101, theres alot more to be fixed then a carb change.

This was why I suggested the pressure readings. Also bear in mind that that was a quote from another source. I also don't agree with the quoted material but that's another thing all together. I think there are other issues besides the carb/stall/cam bit.
