You have my phone number Bob.
Can you show me in my post where I say anything about duration?

Quite A Few People Have Told Me Chris Is The Man. I Don't Think I'm Ever Going To Be Happy Without A Blower. Having Said That If I Could Spin An- Aa Into The 80's-to 90 Range Without The Expense (blower 2 Carbs Ect) I'd Do It. Thanks All.

Correct. I was simply refering to your definition of "overcamming" on Speedtalk where you had this exchange:
Cstraub:
"IMO opinino, the better the heads the less the camshaft. Most cam companies way over cam these heads and it just makes for lazy rpming engines. I cammed a 360 Sprint years ago when the new All Pro head was out. Engine did not make the suspected power, number were reall good. Dyno guy was a customer of mine, he called me. . I had ground something 20 degrees smaller…………"
The response was:

I had ground something 20 degrees smaller and we picked up 60HP and 80#/ft of torque and flattened the torque curve by 800 rpm.
I just got off the phone with French Grimes about his upcoming interview and he made it clear he thinks overcamming is a big problem. In fact, just about everyone that's been on the show and commented on cams has said the same thing. I think it shows missing the duration numbers on the high side is a lot more harmful than missing them on the low side. Reminds me of shift points.

Now that we have redefined "overcamming", back to overcamming for altitude.

Refer to post 42.
Hi Guys. Gn7 I Could Buy Another Impeller? I Guess Asking For A Specific Mph. Is Pretty Vague(spelling) Sorry. JUST READ IT AGAIN GN7 ,ALL I CAN SAY IS I'M WORKIN ON IT.(21' DAYTONA)
I understand what chris is saying on the "over camming" for altitude.Go with the blower and you will be happier.
I believe your exact reference was to "over camming" the engine. What would your definition of "overcamming" be??Not to speak for Chris, but my guess is that he's referring to over-camming in comparison to an ideal grind, which, as stated in further posts (and I completely agree) is typically WAY smaller than most "experts" will tell you is "ideal". I'd say Chris' idea of "overcamming" this engine would still be under-cammed in most people's opinion.
I also know you're noy gpoing to drag him into a pissing match about this.

This post makaes no sense at all except to say it sounds like someone has an axe to grind, pulling a thread from another website to make a pointless point. (Don dosen't let you get away with much of this kind of stuff on speedtalk, does he.)
Please keep what's on Speed Talk, on Speed Talk.
