Re: How will you go faster?
Acceleration does NOT require a torque input! Acceleration = (RWHP x 550)/(vehicle weight x 1.466666 x vehicle speed) Acceleration in g's Vehicle weight in lbs. Vehicle speed in MPH There are a few on this forum who have aided many of their customers to win many BIG championships and set many racing...

Re: Camshaft lobe designers
I wonder what program this is? April 25, 2009 by UDharold - "I am still using the commercially-available program, and all my cams since 1995 have been designed on it. I paid $10,000 for it." I believe before Harold passed he taught Jeff from Koerner Racing Engines how to use his software t...

Re: 0.200 lobe lift duration questions
I recommend you read some of Mike Jones / CamKing previous posts. Look at requirements at the valve and then work backwards, true valve seat timing is very important. Also please list details of your engine combination and goals here. bore, stroke, rod, valve sizes, port flow / port CSA, desired RPM...

Re: Camshaft Overlap@.050" vs Idle Quality
I think I had seen Paul Carter, a very well respected pontiac builder, say that the 704 camshaft was very explosive when you step on the throttle in the 455-467 Pontiacs, and he actually seemed to think the Idle of the 704 wasn't all that radical at all, but I know that depends on the person, some ...

Re: Camshaft Overlap@.050" vs Idle Quality
Thanks! Am I correct in thinking that the Pontiac 467 would idle tamer than the 454 BBC with that 60204(basically same camshaft as 704), due to the Pontiac having a 4.25" stroke vs the 4.00" stroke of the 454? How much will a 1/4" more stroke tend to tame the camshaft? I think more m...

Re: Camshaft Overlap@.050" vs Idle Quality
Cool, what about Idle and drivability comparison between the 60919 and the 704? Will the 704 Idle be more tame, even though it's on the 110 Separation, due to its shorter .006" duration, or will the Idle and drivability be similar between the two? I've heard a couple 60204 Voodoo, which is the...

Re: Camshaft Overlap@.050" vs Idle Quality
Is 17° considered a lot of Overlap at .050" for a 467 cubic inch street engine? Does .050" Overlap even have anything to do with any of this? No, the shelf Voodoo 704 is very streetable in a 455. Outside of overlap, I'd prefer the Voodoo lobes over the Crower. I've seen duration @ .200 of...
