Sorry. I also meant to ask if anyone has had any experience with the new ZZ383 crate motor. Will in run with a TPI intake set-up? Will it pass an etest? Thanks again.

 

One thing is for sure, a stock tpi setup would kill the hp numbers on that engine. If it chokes a stock 350 (it does), it will really choke a built 383. I would suggest either a Holley Stealth Ram or an Accel Super Ram for a PFI setup on a motor like that. Not sure if or how it will pass an etest. I would imagine few, if any, have tried to yet.

EDIT - Welcome to the boards!

 

I"m not too knowledgeable about that engine.. what heads does it have? if they are vortecs, then a stock tpi won't bolt up unless you get a base from SDPC. If a tpi setup bolts up, it will choke that engine quite a bit, but it will run.. i'd reccomend an aftermarket base/runners and a hogged out plenum unless you go with an aftermarket setup like a HSR, superram, miniram, etc.

 

I am in the process of putting one of the zz383's in my 88 camaro. I will be using a TPIS miniram on it. I dont know about the emissions since i am not going to be running AIR or an EGR anyway.

*FYI Those are the Fast Burn heads

The engine is in my car now, just needs to have everything hooked up so I will probably have some more information for you shortly if you are still interested.

here is a pictures of mine if you care to see...

 

Do the fastburn heads use the vortec style intake bolt pattern? I was looking at this motor but I have a hood clearance issue (89 jaguar xjs convertable) and I have been told that there is a one inch difference in hieght between the final plenum hieght stock over vortec. That is one inch I don't have. I was contemplating the sdpc tpi intake w/runners and ported plenum on this motor but I'm not shelling out the cash until I know whether it will fit under the hood. The TPI setup will probably kill a little HP but I'm sure I'll gain some more torque. I'm ok with that as its a heavy car and no gear. I also need this to pass an etest and I'm leary on the duration of this cam.

 

I'm 90% sure they share the Vortec intake bolt pattern.

The TPI setup will absolutely kill the HP the motor is capable of making.

 

as far as horsepower and torque loss with a TPI go... When I am done putting it together I will be putting my car on a dyno and post the results

 

im 100%. their the same pattern

 

Your right they are the same as the steel vortec.

 

i think the new ZZ383 is way overpriced. GM's forged 3.80 inch stroker crank is used in that motor with the rest of the ZZ4 components and its 1000bucks more or so. thats cuz that crank is 1000bucks. you can get a great forged 3.75 inch stroker crank from lunati, eagle, etc for 700-800 or less...

i just dont see the justification to that extra cost

 

GMPP sticks their name on alot of aftermarket parts.
That GM crank is 3.80" not 3.75. Reason being is so that you don't have to zero deck the block. It's a 4340 piece made by Cola Crankshafts. It's a damn fine crank. I know this because I bought one directly from them. By comparing it side by side to the 3.75" Eagle 4340 crank...the Cola/GM one was clearly superior. Yes there are other/cheaper options but I would avoid CAT, SCAT at all costs and know that the eagle can have balancing "issues". Callies makes a good one piece stroker crank and so does Lunati.
Also, Some of GM's performance cams are off the shelf grinds made by Crane Cams including the one that comes in the ZZ383.
I have the next size bigger cam (also a Crane/GM cam).
Crane also makes the roller-rocker arms GM sells and used on the LT4's.
MSD makes their ignition boxes and Fluidampr makes their "Racing" Balancers.
You'll pay more for getting that GMPP sticker than buying them aftermarket. Those GM stickers must be really expensive to make...lol!

 

Had to bring it back from near death...

bourneash how is the engine? Im planning on putting a zz383 in mine when I get back to the states and Im haveing some trouble finding info.

Anyone else have experience with this engine?

 

I have had the engine running now a few times(in park). I am experiencing some problems mounting the alternator. I need to build a custom bracket for it to mount on the passenger side head since no one seems to sell one that will work

Tuning its been pretty tough so far, i've never tuned an engine before and am jumping in to the programming pretty blind(165 with $6e). I can only get it to run stable at a 10 degree advance at idle, not sure if thats right or not for this engine. i did not get to do a whole lot of programming since this alternator mounting/belt routing and sizing is being a PITA.

I have not been able to actually drive the car as of yet since the rear pinion angle has not been set and bolted down(its going to go to a shop for that since i dont know how to do that and dont even know if i could do that myself.

Here are some more pictures of it and a big(33mb) movie of it running:

If you would like pictures of specific things let me know and I will take some for you

I have not ran it to any big problems *so far*(none as far as the engine itself goes). Altought it runs pretty crappy with the hypertech chip which is what i origanally had, definatly will take some chip programming to get it running stable, hopefully i will be able to figure that out

If you have any specific questions let me know, maybe I can answer them for you.

there is also quite a bit of information about the engine itself at http://www.sallee-chevrolet.com/Chev...ZZ383-425.html

 

Well Im still looking at about 6 months before I can start this project and Im trying to find out as much as I can.


Interesting about the alternator. Im going to keep my AC so my alternator will be on the drivers side. Im going to go with a 750cfm speed demon so the tuning wont be as much as you are going through.

What rear end are you using? Im probably going to go with a Strange or a Moser, still not sure.

thanks

 

Hey guys, a little off the subject, but if one wanted to keep the TPI setup, would the HT383 be a good choice? Seems like it would have great low end and be a good stop light to stop light setup?

 

As of right now I have the stock rear in it that came with the 88 iroc. After a couple of hard launches with the transbrake I am sure I will be replacing that and going to a 9". The drivetrain has been replaced all the way to the rear currently. The ZZ383, Spohn drive shaft and torque arm and a th400.

 

It would fall on its face pretty quick. Good torque numbers but 0 for hp and after about 4750-5000 rpm it probably wouldn't have anything left. Might be ok with about an 8 speed trans though. I think the ad for it says it shouldn't be spun past 5000 rpm.
