Like I said, ALL Z's came with Posi..

As for the transmission, it all depends. Personally, I wouldn't go more than 350-400 HP before you'll want to think about beefing it up. Anything below, is safe. Once again, that's all my personal preference, so don't come shootin me if your tranny breaks with 349 hp

 

ya, "today" being before you said this or I read it (insert appropriate smiley face here).

and I know i wont be going over 350 HP, and probly not much over 300. So thanks thats what i needed to know.

 

get the headers when you get the exaust, otherwise youll be paying for them to redo the exaust to mate up to the headers when you get them.

 

o right i knew that

ima get some pics up soon before it goes to the shop for exhaust system, so i can do some before/after.

I think I'm gonna go with a dynomax exhaust system cus of the easy install and like somebody said earlier, half the ppl swear by dynomax the other half flowmaster.

 

Make sure you do your homework before you buy a intake manifold. I don't think the air-gap will fit under your stock hood. I had a 79 z-28 and it had a torquer II single plane intake. The wing nut was touching the hood, i tried to put a drop base air cleaner on but it woudn't clear the linkage on the carb. I think the performer will fit but i'm not sure about the performer Rpm

 

I agree with ZX about the Air Gap intake. I'm pretty sure it won't fit under the stock hood. Also, don't go with the RPM cam. It's an old school design with lazy ramps. The cam I recommended earlier, the Comp. Cams 268H (Hi-Energy) will make more power, idle better, and be MUCH better all around than the RPM cam. I've seen the 268H cam run in a few 350's and even 400's (SBC's) and believe me it's a tremendous cam (specs- 268/268 duration - .454/.454 lift). Chevy Hi Performance magazine even tested the 268H cam vs. the new XE268 cam in a mild 350 like yours and the 268H made 10 more HP and more TQ!!

Check out nastyz28.com (ALOT of information on 2nd gen. Camaros there - "High Performance" and "Engine Topic" message boards). Someone there could even run a ddyno or E.A. and compare your motor w/ the two different cams - 268H vs. RPM (HP and TQ #'s). Good luck!!

 

thanks im registered on the other forums now too.

I have a silly question i should probly make a new topic but what the hell.

What exactly is the purpose of an ignition and ignition box. i'm not even sure what the part is that im asking about but people ask me what type of ignition i have, and i say the kind that you put a key into and turn to start the car. Is there something i'm missing, is it performance related, if so is it worth losing the stock one. Help! im a newbie.

 

when they ask about your ignition they are problaby talking about of two things.

1: the actual distributor. is it stock HEI, Accell, MSD, or whatever.

2: an ignition box (also heard them refered to as spark boxes) you dont have a stock one, so they are asking if and what you run as an aftermarket box.

stock HEI isnt a bad system, so you dont need to lose it, but it could use some improvement. I had great luck with my MSD 6A ignition box, and standard coil adapter. the box definetly made starting easier, and smoothed out the idle big time. though I reccomend the 6AL insted of the 6A, because the 6AL has a built in rev limiter.

you can also jsut upgrade to a performance HEI coil and get a box.

 

Well, to me, about the only thing that an upgrade to the ignition system will do, is MAYBE increase fuel mileage, if your ignition is lacking a certain something, because it will 'supposedly' help the mixture in the combustion chamber burn better and fuller. *shrugs*
The only other thing I can think that it would be good for, is if you're running extremely high compression. It'll give you a much hotter, harder spark, which is needed for higher compression engines.

Other than those two things, to me, there's no point in upgrading, unless you want to be able to retard your ignition quickly by turning a dial on the front of the box. :P


As for the intake not being able to fit under the stock hood, if says anything about 'high-rise' in the product description, there's no chance in hell that it will fit. Otherwise, I *THINK* it will. I wouldn't chance it though, whoever you wind up buying the intake from, ask them if it will fit under a stock '79 Z28 hood. If you're buying it from a friend, or club member, chances are they wouldn't know, but if it's from some place like Jegg's, or Napa, or something, they should.

Just my opinions, of course.
