hydraulic roller cam in a 390

Interesting

Several of those have a wider duration split by a few degrees than the average shelf cam.

Seem to hover in the 53-55 degree difference in ADV/.050. That seems like it might be an issue with fairly stock (heavy) valve train, seems  like they are pushing beehives (lighter)...

Descriptions of behavior seem typically vague and off.

Assuming the the quality is there might not be a terrible choice on the cheap.

Love to hear how it works if anyone try one.

i ran a hyd roller from comp in a 428 cobra jet engine and it ran great,had power to 6200 rpm. tons of bottom end torque,cam was from barry,232 236 at .050  and .565 lift.would not run a flat tappet again.

Shame about the overlap on 8919, little wider LSA would get the vacuum up and the rumpty rump down which would be good IMO.

Also, the cam card numbers don't jive the valve events spit out by wallace on several of them.

Good.

So which cam did you get?
How does it and the packaging look?
Did it have anything other than the cam card shown on summit racing dot com with it?
What springs/retainers do you plan to use?

as far as packaging it was the same as other cams i've bought, whether they be 'brand' names or generic melling ones.  i'm not at the springs/retainers stage yet, it depends on whether i get aluminum heads or rebuild the iron ones for now. it's all budget dependant really. if the used 360 runs ok it'll go in the nash while i collect parts for and build the 390. you never know, if the budget will stretch and the 360 is ok i may get a stroker kit too.

Cool,

I was curious if you were going to get a fancy report form their supposed super duper quality checking thing ma bob they talk about in some of the "articles" about other PRO Series cams.

that cam card doesn't match the one on summit racing dot com. IVC 71 to IVC 77 and 10 degrees more Advertised is a pretty big difference. Also your cam card indicates 1.75 vs 1.76 rocker ratio.

The discrepancies in the specs on these cams are wild.

Be interesting to run one across the cam dr and see what it really is and what the ramps look like.
