Setup Suggestions??
Setup Suggestions?? I just bought a 94 z28 camaro A4 and I am going to be doing a few modifications
I've got a little over $2000 to work with in order to get this accomplished. Below is what I plan on doing so far. Anyone have any other suggestions that might fit into this budget?
Mod list:
LS1 Style air intake
CC306 cam on 112lsa
P&P stock heads
Pacesetter Lt's
True dual exhaust
2800 Stall
Computer Tune (MadTuner? Suggestions?)
Thanx Guys
P.S. Anyone have any idea what kind of power or 1/4 mile times to expect with this setup?

you should definitly do gears if you have 273s. i would also go with a bigger stall to go with that cam. maybe a 3600? you may want to raise the budget if your gonna go with a cam and pull the heads. all those little things like a timing chain, gaskets, rockers etc. will raise the price.
Sorry, I should have specified, The car has 3.42 gears but I was planning on sticking with a stock bottom end so I didn't really want to rev the engine too high.
About the stall I don't really know what to do... I have been told that LT1's make a lot of low end torque so i was trying to keep the stall low, but if It would be better for 1/4 mile times to make it a little higher, I'm open to change

342s are fine. lt1s do make a lot of torque down low but with the cam you selected u will make peak torque/horsepower way up higher in the powerband. if your not wanting to spin the motor extremely high you may want to check out the cc503 cam. it make more power down low than the 306 but still makes good power up high.
Well my goal for the car is to make it faster than my previous LS1 T/A. Shooting for low 12's hight 11's. I realize this may not be possible on this budget, but i have heard of it happening with similar setups.
What kind of RPM's can a stock bottom end hold up to? I am changing out all the bearings in the motor as they have substantial wear.

personally i wouldnt go above 6300 RPMs but there are the guys turning 6700 with no problems. a cam only car can turn low 12s.
with your budget, i would buy at least a 3600 stall, and work on the suspension. your not going to turn low twelves with no traction. i would then consider maybe changing the cam after all the boltons. i really dont see you getting the heads worked for 2000 dollars with everything else your getting.

well, I have a friend who has a machine shop... and I'll be getting the heads worked over for around 500 so that will help

I worked it out and I'll have enough for everything on my list plus misc stuff such as timing set, pushrods, etc. for around 17XX I actually have most of the stuff already in progress, with the exception of the cam. That is really the one thing that i'm unsure about

Verdad Gallardo the cc306 is a good cam, but it will peak alot higher than i would recommend spinning a stock bottom end. there are guys who run it successfully, but there a lot of guys who hate it. i am going to change out my cam along with the torque converter this fall and will be going with the cc503. i think it peaks at around 6200 rpms which means you need to spin it to 63-6400 rpms to make peak power. there are alot of cams out there for a lot of different setups. check out the sticky at the top of the page, it has alot of info about cams for these cars.
ok, I was under the impression that the 306 peaked around 5800. The RPM range on the cam card says 1800-5800... I was only going to do the 1.52 rockers, not the 1.6's.
Comp's rpm ranges are WAY WAY off for the LT1. My best guess is they applied gen 1 duration=rpm rules to the LT1 neglecting to consider what our intake manifold does to rpm range. Reality is that cam is a **** poor choice because you will have to rev it roughly 1000rpms higher than they are claiming. The cam I am running is closer in size to the 503 and I take it to nearly 6500 sometimes right to 6500.
The TCI is a bad choice as is 2800 stall, best any knowledgable person will say about the TCI converters for this tranny is they are hit and miss. Get a Edge, Yank or Vigilante and go at least 3200 stall.
On the heads, he must be using leftover hardware or something because decent springs/locks/retainers/seats will easily cost over $200, using dirt cheap valves they would be what another $100 and you could spend a lot more on these items, not leaving a lot of money for the other work he is going to do.
heads are the key to power, don't cheap out on them and waste a set of castings. Stick to the boltons for now and do the heads when you can afford to do them well. Ported stock castings are the right choice for the overwhelming majority of folks so I am not saying go aftermarket. I am just saying don't hack up a set of stocker wait and do them right.

The engine builder I'm using builds a lot of drag cars, what it boils down to is that I am getting used parts off of him that have only maybe 500-1000 miles on it, but he pulls the stuff off of the heads from his high end customers and is able to re sell them at a decent price to average joe like me. as far as the valves go they are Highflow valves. like I said, the guy is a friend of mine and is doing the work for next to nothing. The heads are getting a valve job, bowls ported, and he's milling the deck down .01 to remove the divots put in by the last guy who had this car, Dumbass took a wire wheel to aluminum heads!
with the stall, I know TCI is hit or miss, My buddy had two bad converters right out of the box.
