Default Re: Stocker Cam Lobe Profile ?

This is GREAT !...
I'm 3 times as confused as I was before ! ! !
HE HEE !!

Facts and numbers

The engine makes about 45 HP more than anybody ever did with even a "resembling Stock" 409 before.
Speed through the traps is at least 4 MPH faster than anybody ever went.
My bottom end is legal... piston/rod weight is dead on, combined combustion chamber volumes of the block and head, are safely within spec.
All that I have done different from everybody else with these things, is a big-azz camshaft, and big-azz headers ! Seriously, when tested... went from an EXCELLENT set of 1 7/8" tube, to my own 2" stepped to 2 1/8". Torque curve moved up, peak torque went up by 17 ft lbs, and the engine made 21 more HP.

The old "torque thinking" just doesn't seem to apply to this short stroke engine. Unrestricted ( for the CID ) carburetor CFM, I believe, is also a reason to pursue the escape of the mid-range torque concept ?
I dunno ?.... other than the intake valve going out of control... this damn thing really works.
So, at the moment anyway... fix what's "broke" ( square cam lobe )... and leave alone, what seems to be a really good "package".

assymetrical cam lobe ?
THAT may be the very compromise that I need !

You guys are amazing... Between the support I get here, and the practically "out of body" experience of attending places like the race in Mission... I'm getting hooked on this REALLY bad !
