is this still availaable. Is this appropriate for a mild build. just a step above and original 1971 engine
Also curious how the massive intake/exhaust spread affected the engine. What was this cam in? The design of this particular one confuses me. Can anyone enlighten me on what the massive split combined with low lift on the the exhaust would be good for? High exhaust velocity through a small port? @LARRY70GS ?
The exhaust ports on iron heads need help. They don't very well at all. So to help it Scott put extra duration into the exhaust side to give time for the burnt charge to leave the motor. Even on a set of well ported iron heads.......heads I ran 10.90s on......the difference between .400 lift and .600 lift was only 10cfm. The piston is closing in on the exhaust valve on its was up on the exhaust stroke.....so I'm guessing that Scott was keeping the valve open longer with the duration, but the short lift was to not put the port's into a stall of situation where the flow numbers started going backwards, while also providing piston to valve clearance with the extended duration by not having the valve way out there. This is my best though, you can always call Scott and reference the build number and ask him directly
Hi, looks like *2121. Sorry I do not know much about the cam and I never ran it. Bens Thank you for the help. Nelson
I might be wrong in my guess, that's why it best to call and get the info straight from the guy who dreamed it up. I know Scott does things a little different than most, but he seems to have a gift at figuring and knowing what works to make power. I would never question him if he ever made a recommendation. He is the designer of the cam in my current motor which has yet to roar to life.....but maybe in the next 30days
Not that unusual. Ever look at the 118 cam? 228/247, but on a 118* LSA. As stated, it is to crutch the poorer exhaust port.
Yes it is a 455 The cam gear gives it away see picture there's no threads for a bolt for a 350 cam gear.
