ZZ9 cam vs. crane 2032 cam
I have a 1988 iroc z Camaro with 350tpi. It is an automatic with 3.27 gears with a fti 2400 12in. stall converter. I plan on putting summit racing 62cc 170cc 2.02 1.60 aluminum heads, flat top pistons, and first tpi fuel injection intake. Which one of these cams will be best for this setup and make the most power and have the most lope? The zz9 cam specs are 212 226 483 520 112lsa. The crane 2032 cam is 214 220 112lsa 482 496 lift with 1.6 rockers.

Re: ZZ9 cam vs. crane 2032 cam
For a decent, fun, street 350, I think those are decent heads. The 170 port isn't huge, which favors street-able low RPM torque. From what I understand, for a small port, affordable head, they flow pretty good. sounds like a good foundation for street 350.
You need a good street cam. I think both of those are good choices on paper. I had a zz4 cam in a similar 350 and it's a smidge smaller than the zz9. That being said, both cams are old technology. Current cam manufacturers have cams that spec out the same (or close) on paper, but have more advanced lobe profiles (the actual lobe shape). I had specs in mind for my current motor, but couldn't find a newer grind so I called Lunati and had a custom Voodoo cam ground to the specs we discussed. No extra charge, but no doubt they'll have an off the shelf cam similar to either of those two. Their tech line was very friendly and super helpful.
Unfortunately, neither of those cams are going to lope a whole lot. My zz4 cam was enough to know their was an aftermarket cam, but it wasn't turning heads at the cruise in. The higher duration cams have more overlap, when two valve are open at the same time. This creates turbulence at low rpms and you hear that chop. They make less torque down low, but more power up high. BUT...the whole engine has to be built for high RPM power. Heads, cam, intake, and driver/engine intended use has to all match.
...and keeping with the street driven, torquey, not so high reving 350 idea, I'm not sure I'd pay the cost of the FIRST system. In fact, your stock TPI or even an aftermarket TPI would be fine. ...and the Holley stealth ram, for half the price of the first will be every bit as good on a 350. ...it's not until you need the extra air of a high reving 350, or 383 (or bigger), or maybe a purpose built race engine that the Holley Stealth ram or FIRST system really shine. However...the Holley is cheap, and doesn't really hurt much if it flows TOO much, which is why it's so popular.
I had a 2400 stall with a 3.27 gear. It was a great combo. I'm guessing you already HAVE the rear, since most people don't BUY a 3.27/9 bolt???? I'd like a 3.42/3.45, but if you HAVE it already, keep the 3.27. MINIMAL difference.
It's late. I'm rambling. Hope this helped some.

Have you upgraded your exhaust system?
If not, you are putting the cart ahead of the horse.
If you are more interested in how the car sounds, rather than how it performs, then the BIG ***** THUMPER is for you. http://www.compperformancegroupstore..._Code=THMSBC10

Re: ZZ9 cam vs. crane 2032 cam
The car has a magnaflow catback exhaust with no cat. I will be putting on 1 3/4 dyno don shorty headers. I was gonna go with ported stock base, plenum, Arizona speed and marine runners all matched up to each other. I figured for a litle more money, I could get the first tpi system for $1050 or more. It would outflow the other setup by far and have more potential and more topend. I like the look of tpi.
