340 dyno chart thoughts
I hear you on scavenging and reversion. But on a typical streeter neither of these really become issues.
Even the 292/508/108 is not a big deal,as to reversion. and with typical headers and street pipes,"over scavenging" should not be a problem. I ran twin full-length 3inchers with that cam, in about an 11.3- 367, and while it liked it's gas allrighty, I blamed it on my driving style.lol. I only had that cam one summer, finding it waaay too big for me. With 3.55s it was soft off the line and by the time she woke up I was speeding in first gear. Fun?heck ya! But too soft below 30ish MPH;even with 11.3 Scr. I moved it three times at least, with little to no improvement. It was pretty good with 4.88s tho. Finally, I yanked it.
Don't laugh,but I replaced it with a 223/230/110. I loved that cam.I had to swap out that thin head gasket tho. I loved that cam.It was a beast.lol
