67GTA - must've been a mistake earlier...I was basing my opinion on numbers you posted earlier in this thread...
...the .588 lift spec sounds better and since it is a solid will make a lil more power vs the hydraulic, I was pointing out that what you posted earlier seemed a little small >>a 286 advertised duration and .540 gross lift cam didn't seem very stout at all for a BBF, especially one with $6500 in mods...the fact that you have improved the exhaust and intake and thus improved breathing ability, should better make use of your cam. I do agree with your assessment about the ignition...a good spark is essential to making power as well as a good tune.
BTW, out of curiosity, what brand cam did you go with and what's your duration at .050; is it a split or single profile cam?
