I bought this cam from pb performance specs are as follows

Lift @ cam Intake .308 @ valve .462
Lift @ cam exhaust .319 @ valve .479
Cam timing @ .005
Intake opens @ 34 BTDC & close @ 66 ABDC adv. duration 280
Exh. opens @ 83 BBDC & closes @ 27 ATDC adv. duration 290

Cam timing @ .050 intake opens @ 1- BTDC & closes @ 33 ABDC max lift 107 ATDC duration 212
exhaust opens @ 48 BBDC & closes @ 6- ATDC max lift 117 BTDC 222

Question is what do you guys think of this cam, Is it too much or too little?
Also Should I degree this cam?
All help is appreciated.
I have hedman full length headers stock tpi set up for now.

 

Looks like an old design with long lazy ramps, designed for a carb application. Not appropriate to fuel injection. Also, not a roller.

Wrong cam for the application at hand, it would seem.

 

Wow all these mebers and only one response. Any one else?
By the way sofakingdom. This cam is a roller cam and is meant for fuel injection. that much I do know. the part # is 34002. the 3 represents roller the 4 represents chevy and 0022 is actual part #. I am just trying to get opinions on the actual specs.
Thank you for the reply.

 

My opinion hasn't changed.

Looks kind of like a GM roller cam in that regard; like the L03 cam for example. They just directly copied the legendary "peanut cam" lobes onto a roller blank. That didn't make the profile any better.

For a good contrast on a roller cam, look at a modern cam with the same .050" duration; such as the Comp XE264HR. Note how your lazy cam has 280° of "advertised" duration, compared to 264° on the modern cam, but yet has the same .050" duration; although the lobe lift point for the measurement is not the same, i.e. it's not a totally apples-to-apples comparison, I don't think that .001" of lobe lift is going to make that much of a difference in the "advertised" duration measurement. Note also, the difference in lift.

My opinion on the specs remains, that it's an inferior older design with long slow lazy ramps.

 

It seems that Sofa is right about the long ramps. The lifts and durations would be fine. What's the LSA? Looks like 112 to me, which is fine.

Bottom line is that the cam will work, but it's not a very agressive roller-type profile. If you've already got it, I'd say use it.

 

you are correct 112 is lsa. What would you guys reccommend?

 

Look at the Comp XM264HR; or their "302" grind
