K, i have read alot and im am beyond retarded when it comes to motors / mechanics and the likes. I have a guy building my 350 and asked what cam i would like in it. I was like hell if I know!!! so im asking all you smart 3rd gen motor peeps what i should do. its mainly a stocker, i want to just drive this car around. it wont see a race track, but i like to stab it off the line. it has a t5 5 speed and a posi rear that will be getting new gears. (its way too high, the car was auto) its a 89 trans am tuned port motor. anyway, he was throwing numbers at me like 252??? and no higher than 260 ??? for the cam. i have no idea what he is talking about. this computer also has a hypertech chip in it if that even matters.

what i want:
what cam should i buy??? (the specs)

found a good thread! it takes some time, but if you look long enough you can find stuff! so i think im going to go with this crane powermax 2032. from this attached thread it looks to be good.

U know ur gonna have to tune it or get it tuned after a cam swap right ? U want something with not alit of overlap .. And some more details would help us help u .. What gears ? What else is done to engine ? Headers ? Intake ? Good rockers ? Compression etc.

oh you guys ROCK!!! its so nice to be connected to people who have specialty skills. OK, so the rear end i am going to re-gear, im thinking somewhere in the 3:50's to the 3:80's range. i have the BW 9bolt gta axle. as far as the engine, it was machined to .020 over bore, new pistons crank job, heads redone, valve job springs rockers ect. it is all done just stock tho. nothing fancy has been done. so im guessing just a stock cam is what i would do. i was just figuring since i have to buy one, may as well get the best for the app. oh headers i need them too, and intake is stock tunned port injection with all the stock stuff there, intake and all. compression im not sure on. I could ask the engine guy.

thanks so much again!!!! i really do appreciate the help and knowledge!!

alright, talked to engine guy hehehe he says its going to be around 8.5 to 8.75

All the major cam companies have forms you can fill out on their websites and they will recommend a cam based on that.

You need more compression, tpi motors came with over 9:1, dropping it from stock will only drop power and effeciency, unless you plan on adding a blower or turbo!

KBD85

he just talked to me again, he thinks the cpression is going to be close to 10. we got this as a basket case, been rebuilt but put together shitty. he is thinking they may have even bumped the compression up as the pistons are "flat top" what ever that means. he was saying staying close to stock would be my best bet.

NICE! K, i will try that and see what i come up with.

thanks again so much! im loving learning so much about motors! im more on the body work side of things, but its nice to know a little about the mechanics

No! Don't do that! If you're going through a rebuild and are going with 3.70 gears and a T5, get a cam that's a little sportier.

With TPI you don't want to get into a high RPM cam, so the Comp 08-500-8 recommended above will be very good. It's similar in duration to a stock cam but with more lift. I would even go with the 08-501-8, it will run even better, sound better and still be very tame with your setup.

^ 08-501-8 is what I went with.

WOW!!! OK, poking into this part of the car is like opening a can of worms! there is so much info out there, and im also seeing, you cant "just pick a cam" thanks for the info on this tho! i am realy enjoying the reads and seeing what this realy is all about
