I have a brand new Web cam for sale. Its a custom cam that takes the 493/729 and adds a few more degree's of duration.

I know nothing about this cam other than what Im telling you. I know Web gets $285.00 for off the shelf cams so this one may have been more. I got it in a package deal and I have other cams I run.

Really no need for pictures, it looks like every other web cam!

$200.00 shipped

Thanks Gar! I have a feeling this is a good power producer for a big bore....like a 480-500. Probably has a nasty midrange. You guys know how I feel about Web cams by now I and I dont run them so Ill never know what it will do. The standard 729 makes good power so I would bet this is even better. I always felt they are harsh on the valve train though.

Its the 729 version.
I did the specs working backwards:
We know int 110 lc and exh is 104 lc.
We know int is 252 dur at .050
and the exh is 252 dur at .050

So we have int opens @ 26 BTDC and int closes @ 46 ABDC
then the exh opens @ 40 BBDC and exh closes @ 32 ATDC
You have 58 degrees overlap

Just add 2.5 degrees to either int or exh, Im not sure which lobe has the +5 added duration.
Know you know the cam specs.

Bump for the King!
