look at the specs on this cam grind...found this on ebay. Wondering what this kind of cam would do with a manual transmission, stock ratio rear end...4 barrel carb (probably a 500 cfm) with hi ratio rockers and C heads (292 standard bore)

Numbers are; .495” lift, 237 Deg. At .050”, 113 Deg.Sep. 282 Deg Adv, Lash at .016”

I would think that much lift already has the hi ratio rockers calculated into the equasion.

Whos grinding it?

That sounds like a 'sporty' cam, but with such a wide LSA, it should be livable on the street. I'm sure Ted will give a more detailed description of how well it will work.

My thoughts are a 292 standard bore with C's isnt going to have enough static CR to handle the cam, unless major loss of low end performance is tolerable.  The cam's preferred rpm range may be out of range for the engine's bottom end hardware.

Also, if .495 is the correct total lift, I believe shortened valve guides are required.

Knowing the brand of the camshaft always helps.  But definitely not an automatic transmission cam unless there is a stall converter in place.  And with a standard trans, this cam will like at the very minimum 3.89:1 rear gears and be installed about 4° advanced.  It would be nice to know what the lobe lift is to verify what rocker arm ratio the advertised lift is calculated from.  As an FYI, Isky uses 1.5 for the rocker ratio which is middle of the road while the Clay Smith cam card I have sitting here specifies the 1.54 rocker ratio.  I have a Crane Cams spec card that lists the lifts using both the 1.43 and 1.54 ratios.

thanks for the input everyone....I have decided to leave it alone.
