Default Zz9 cam Q's

Is it worth putting into an 88 Tpi that's been bored 30 n potted intake/heads?

What's it worth used?

Have a friend with a used zz9 roller cam 700-118, appears to be in good shape n has the roller litters too. Everything he owns is clean n in great shape! His 9 second lt1 fun car is in impecible shape n has a/c. All tastefully done too

Yes it is worth it. You will need a tune to get the most from it. Wouldn't give more than $150 for it. Try for less.

It depends....If you potted your intake with flowers, I'm not sure it'll help. Seems like that could impede your air flow!

Otherwise, it will. There are other cams that will help more but it's not the worst choice out there.

I've potted things before, but never engine pieces.....

seriously though, I run the cam currently; been running it for 7 years or so....my build originally consisted of an Edelbrock base/runners with the rest of the mods. you see listed below before going to the miniram. The cam is probably (it is) smaller than I would like now with the miniram, but it is a great performing cam from off idle to 5,800+ RPM. short enough duration to get the car out of the hole fast with low end/midrange grunt and pulls fairly well into higher RPMS; great set up with long runners since it works well in lower RPM ranges; may not be the best for a miniram intake like mine; put it this way my car is putting down 362rwhp with it; Corvette Fever managed to get 380rwhp with the ZZ9 in a 94 LT1 car by installing aftermarket heads (forgot what kind), upgrading to 1:6 ratio arms, headers, exhaust mods....and run a 1/4 at 114 mph with 4:10 gears (6 speed car) with Speed Hound Performance at the helm on the mods./tuning

One of the few C4 articles I think the magazine ever covered.
