Anyone here run Comp Cams .650/.650 lift solid cam? (pn #23-630-5, 324 dur, lobe sep 108) Do you install it straight up (108)or advance it? What does this cam like? 540 ci RB, 3000 lb A-body, back half car, 4-link, P/G. Only runs 1/8 mile.

Thanks,
Brian

I think that is the cam I have in my barracuda . Computer died so I lost all info. Anyway you better have a high stall converter because it doesn't start running smooth till about 5500. pulls to 7500

I use Comp cams stuff...286-750, While it is a bit bigger, I used to try and adjust to "the flavor of the week" and at least in my stuff they always ran the best straight up.

That cam has a ton of duration, so I would try 106 to start.

tons of duartion power glide 1/8 mile I'd think 104 or 106. But if its like a 6000 stall and big gear that would change things. shift point as well.

1/8th Mile, I'd want it about 102-103...try to 'use it all up' by the stripe

Unless you got really big high flowing heads and make power way upstairs...then I might go 106....you didn't say anything about heads but with a 540 incher I'm sure your "packin'"

i believe the McCandless stick was based on the small ports and lots and lots of compression...if you've got a (relatively) bad port you try to open that valve as long as you can so "something" can still get in there at high RPM.

The longer the stroke the more closing the valve too late can sometimes work against you, after BDC you start to give up a higher percentage of effective displacement per degree realtive to a same cube motor with a shorter stroke.

Sorry, I forgot about the heads. This engine runs the cast iron Indy heads, some port work, but not max wedge size. This is the same cam that he has run before, and yes, it does go good.
