I have a 1994 z28 with the stock lt1. Im going to be adding full exhaust cai and probably 373 gears. What all is needed to make my lt1 reach 400 hp to the wheels and still be reliable enough for me to drive it to and from work everyday about 40 miles a day. I would like to keep this n/a no turbo or supercharger and not interested in nos either. Im also going to get the strano springs and koni shocks along with lcs'a and the other suspension mods. Im probably going to be looking into some 315's for the rear after i get all this done. Any good websites and combo's would be appreciated as well. Thanks guys.

well i have to pass emissions also. So i dunno if a big lumpy cam will be good for me. Where can i get a good head and cam package??? Im going to be getting the motor rebuilt and a couple months and im also going to do a t56 swap as well. thanks for the quick response. Any info on head and cam packages and where to get them would be awesome if anyone can chime in.

Get a Le1 cam and le2 heads. Llyod can cut you a cam to pass emissions. You will break 400rwhp no problem.

You can get an emissions-compliant cam from most of the major ported(or aftermarket)-head / custom cam vendors.
400rwhp may be a little high for an emissions setup, but you can certainly reach into the
375 range with a ported stock head and custom cam.
Get ahold of Lloyd Elliott (nighttrain66 ; nighttrain66@msn.com) and he'll hook you up.
I've seen at least a few people here and over on CZ28 with his emissions stuff.

AirFlowResearch (sales@airflowresearch.com)
and Advanced Induction (sales@advancedinduction.com) should also have options for you.

400 rwhp and pass emissions.......hmmmmm that may be a tough one since you want to stay NA (the emissions part not the 400rwhp). advanced inductions or lloyd elliot seem to be the top lt1 head and cam package providers. call one of them up. also don't get caught up on hp numbers focus on the et.

wow thanks guys. Yeah im not really worried about the numbers i just really want my car to wake up. Its bone stock right now. I hardly ever go to the track so it wont be anything more than my daily driven fun car on weekends. I would love to be pushing 350-400 to the wheels and still be able to pass emissions here in az. Ill definitely give lloyd a call and get this stuff started this winter. Im hoping to have a good chunk of money this winter for all my mods or at least by next summer. Im gonna order bolt ons and stuff in the next month or so and then work on the suspension stuff and then get the motor stuff done.

oh yeah definitely. What do you suggest as far as roller rockers and stuff like that. Im probably gonna have the engine rebuild and stuff done by a well known shop here in az called top gear motorsports which do alot of work for lt1 guys. As far as the bolt ons im thinking of going with kooks long tube headers with a catted y pipe and slp loudmouth 1 cat back. Some good 3.73 gears and whatever cai i can find for a decent price. What elso is needed when it comes to bolt ons other than suspension stuff. Like i said this is my daily driven vehicle so i dont need it set up for track use.

ARP 7/16" studs
Comp Promagnum 1.6 NSA Rockers
TFS Guideplates
Comp 1-peice Pushrods
Comp 850-16 lifters
GM "Impala" Lt1 head gaskets (.029") [the Mr Gasket .026" ones seem to get damaged a lot in packing]
Arp head bolt kit (better yet, head stud kit)
New timing chain
36# SVO or Lucas/Racetronix injectors
A proper tune
That pretty much covers the bolt-ons that are required.
A 58mm Tb and the intake ported to match would be a great compliment to the H/C

you can hit 400rwhp with a hotcam if you have the heads. There are many guys on cz28.com that pass emissions and lay down over 400rwhp. Your just going to need better heads to make up for the small cam. And you are going to "need" all the supporting mods. (58mm tb, ewp, LT's, etc)
Talk to Llyod and see what he says.

yeah im definitely going to. thanks for all the info guys. I cant wait to be drivin around town in a 350-400 hp beast. Looks like im gonna have to start piecing together all this stuff slowly but in the end its gonna be awesome i cant wait. How long will my stock ten bolt last with this much power as long as im not launching it with sticky tires all the time??

I've put a few dozen 1.5 and 1.6 launches on my girdled 10bolt with 3.73s and DRs.
Granted, I also drive an auto with a 4000 stall.
With an M6, it won't last long at all.
With an A4 and DRs, you'll probably get away with it for a while.
No guarantees though.
One thing is for sure, it will happen at the worst time and everyone will be watching.

(or worse, no one will be around to help you tow it home)
Kinda like the time I found out my car doesn't have a low fuel warning light.
3am, middle of farm country, barefoot and no wallet of cell phone (long story), no open gas stations for miles.
Made for an interesting night.

yeah true that man. I guess the rear will need to be taken care of as well. I hate that gm didnt give us a beefier rear to handle the power.
So about this barefoot no phone no wallet out in the middle of the country situation
what the hell were you doing lol

I had only owned it a week or so at that point.
Didn't really think much about it, I mean who needs a wallet and phone to go around the block?
Besides, if I went inside the wife would know I was up that late messin' with the car

Apparently, I got a little carried away with my cruise.
Completely forgot about the wallet and phone.
Remembered the shoes when I stepped out of the car to start pushing.
I was fortunate that someone stopped by in a pickup truck.
I used his cellphone to call the wife. Yeah ... that didn't go over so well (my kids were like 8months and 2years old at the time)
