- ZZ4 350 (24502609) -- The original high-performance 350 Chevy crate engine. Using L-98 Corvette aluminum heads and a cast-iron 4-bolt block, this small-block Chevy delivers 355 horsepower on pump gasoline. More information at: www.gmperforman...
love this engine, for classics the 350 will always be my favorite, this engine is reasonably priced, and can put it in almost everything I like
@ Pat Petit, While the zz4 is a 350 chevy, it is not the same engine as your stock 1979 Corvette, which was rated at 195 hp and had 8.2:1 compression. The zz4 has the newer style 1986-up block with one piece rear main seal with aluminum L98 cylinder heads and a roller cam and makes 355hp and has 10:1 compression.
i have a zz4 in a 1979 chevy Malibu classic it has a old cast iron case power bw brute super t10.it has started for over 9 yrs. it is very reliable i had 327 l79 but you had to rev them.to make any power the zz4 the power is right off idle.
I have the ZZ3 which is basically the same thing with a couple minor differences, I have the LT4 Hotcam and 1.6 roller rockers and make right around 400hp which is about maxing out the L98 heads. I love the powerband though, it makes power from idle to 6,200 rpm.
I don't know what my name is I'm running my original '73 block in my Nova, polished heads and valves, very mild hydraulic flat tappet cam, bored .30 over, DyanMax headers, edelbrock 600cfm carb, and edelbrock intake manifold. Car is making 260hp @ 4,200pm and 316lb-ft @ 3,800rpm too the rear wheels, through a mostly stock TH-350 trans with a B&M shift kit and stock 2.73 rear end. That should be about 300hp, 363lb-ft at the crank. My engine is all low-end grunt, but still runs out too about 5,800rpm.
Threw around the idea of getting the heads ported and a hotter cam, or just new heads all together, but ultimately decided not to. I'm perfectly fine with 300hp, 363lb-ft, as my Nova is a daily driver, not a Sunday-only car!
NovaMan 350 I have a 2.73 open rear end, it kind of sucks. I'll upgrade to something else eventually, probably 3.42. I have a 700r4 and my 1-2 shift is at 55mph and I can do over 100 in second, luckily I have enough torque that my car is still quick but it could be a lot better.
I don't know what my name is 700r4 for a 400hp car? A bit heavy, no? A well-built TH350 should work better with 400hp, as it weighs much less and gets power too the ground better.
That said, the 700r4 is an undeniably great trans. Will certainly last forever.
Wth my car, my 1-2 shift (at WOT) is about 30mph, then 2-3 shift is about 75mph, and it'll top out at around 140mph. At that point, my valves are floating a bit.
NovaMan 350 I have an 86 Iroc Camaro, 700r4 is the stock trans and I like having overdrive. I had it rebuilt and beefed up quite a bit 2 years ago so it should last a long time. My car originally had a 165hp 305 so I can only imagine how slow it was with the stock motor. My car will go faster than I will probably ever go in it, it's been to 155 mph on gps and I let off, that was fast enough for a 28 year old car with shit brakes and cheap tires on the rear.
Got this in my 1955 Chevy 3100...Love it !!! Run Schaeffer's 30w year round....
(Covered in billet chrome, nice extra touch)
I saw a Boss Hoss motorcycle with this engine a couple years ago.
I use the vortec pulley setup with flipped and notched canton racing fabricated valve covers to clear the AC and roller rockers .. And a re welded 4.3 vortec water neck. (Rotated)Even has the lift hook.
I have one in my '50 Olds street rod, perfect combo.
Looking for the best long tubes for my headers for this engine.. Any recommendations?
Geting zz4 next week let u know how it goes
Well???? It’s been 10 months... what’s the verdict?
Nice, the ZZ is a great engine.
Would this motor be ok for my 79 Chevy 4x4 Scottsdale,??
i buy a C3 with this engine two weeks ago. I don't know how much oil this engine needs. Can anybody help?
Rockabillybernhard Depends how big the oil pan is.
Rockabillybernhard Most likely right around 5 and a half quarts.
Check the Dipstick
can this engine be used in a 1992 rs camaro, 305 v8 engine compartment
mark simms: yeah if you convert to a carb set up it should bolt right in. The mechanical fuel pump may have clearance issues but I doubt it will. When I got rid of my tpi305 in my 89 formula firebird and built alot meaner stroker 383 than the zz4 350. I went with a "Holley blue pump" outside the tank electric fuel pump. It also comes with a fuel pressure regulator. My stroker 383 makes 487rwhp through a t56. I originally replaced the stock 700r4 with a th350 with a 9" tailshaft so I could use the stock drive shaft. It was a fully built racing unit with a 3500rpm stall and full reverse manual valve body. It only lasted about 5 months and a couple of 125shot nitrous hits (engine and kit are designed for a 300shot). After the th350 burnt out I converted the car to a t56 6 speed manual from an Lt1 camaro and had it upgraded to handle the power. I used McLeod hydraulics (tick is better) because the factory master and slave are restrictive junk. I used a centerforce dual friction clutch but it only lasted about 9 months before it needed to be replaced, it would likely last a very long time behind a zz4. That clutch also wouldn't hold anything stronger than a 125shot with my engine. A spec stage 3 clutch kit is what I've found to work best for high horse power applications. If you plan to run the zz4 as a carbed engine (I would if you want real performance) make sure the kickdown/TV cable that controls the 700r4 is setup right on the carb or it will kill the transmission. It is a pretty easy conversion. I built the 383 and swapped it all when I was 16 years old back in 2000, in my drive way and I still have it. Good luck with it and do it right the first time or it will cost you more in the long run.
thanks for the information
Do it. I had a z28 3rd gen (same as yours) came with a 305 auto. Kept the tranny. Had it done over and beefed a bit with a shift kit. It had overdrive. No stall. 4.10 gears. Put this in it. With full headers and 650cfm carb. It was worth it on every level. Great at burnouts and drifting around. I'd recommend a car spacer. I went with a 3/4" and it made a big difference in throttle response . Had 2 3/4" exhaust with flomaster 10s. It was a college hot rod
They deleted the PCM on my 87 IROC and swapped in a ZZ4. Now none of the gauges work... any info or possibility of a stand-alone computer? Something to get the damn gauges to work
I've got one going into a 92 camaro vert right now. Changing to alum heads 190 64 .
So they basically use the 3970010 block? Thats what i have in my 79 firebird out of a 79 vette, it puts out around 370 high range hp stock
i would want to check the smog pump bypass pulley bracket installation.. i think its on upside down.. there should be more deflection in the belt between the bottom of the ac compressor pulley and the passenger side of the crank pulley.. this would also increase the belt tension .. i just does not look right to me..

I wonder if you can omit the AC pump on purchase?
Yes
You guys can send me one to try out, I'll put her to the test!
Add that to my stolen cars
I want the receipts too and I want my motorcycle my 2020 lower ass I want thatit's not your motorcycle it's my motorcycle Robert O'Neill's look who's account it was purchased under who was the cosigner Perry now I said he's the corporate owner yeah he forced my screenshot on piece of paper and that's what they've been doing to me for a year now 3 years up to six
would a 700r4 work ok with say about a 300-350hp engine???
Daniel Delgado how much torque?
If built right it will. The 700r4 isn't much different than a 4l60e and they live behind LS1 cars just fine. I've seen 700r4 transmissions live behind some pretty stought engines. You just have to make sure it is built right, has a good trans cooler, has a proper rear gear for your application, and is set up right with the kickdown/TV cable on the carb.
I have this engine in my $198K 1936 LOW ROOF pickup and I have never ever got it to perform like a 400HP should! It`s pretty much a "DOG" IMO! I`m contemplating buying anther boat so I can have a really good use for this engine! Thanks Rod.
Check the heads. Maybe you have the low comp small valve ones. Could upgrade them .
find a tuner
What's the part number for the spark plug wire separators
love it
how much for the turn key zz4
I know I will get shitted on for saying this but...can I put this on my 2016 Honda Civic . Seriously asking 🤔
If you do that for the love of God make a video. I want to see somebody do that
How much will this set up coast
Deanthony Henderson Around $5k for the full setup ready to drop in. I've got one in my '51 GMC and it runs great.
What transmission should come with it
None. Still gotta get a transmission to go with it... which is mostly personal preference. It isn't a super beast motor, so just about any trans that will bolt up will work fine for daily driving applications. I use a 3-speed out of a 72 chevy truck. Its geared a little low, but its perfect for cruising around town and some highway. Would've gone with something different, but I had one laying around, so I used it instead of buying another one.
Yea I'm looking to change the stock motor out my 1986 Buick regal with new motor and tranny
Low low price 3500 obo just advertizrling
I need a 85 350 rv engine
L98 heads are not "free flowing" ... in fact they flow less than stock production heads of the 327 and 350 Corvette of the 60's. GM made aluminum heads with a C grade flow design and made them the stock units on the C4 Corvette. Thanks for the aluminum .. no thanks on the restrictive design.
Aluminum Bowtie heads .. or Aluminum 461x heads would have been preferable. You know this. You have flowbenches.
what kind of oil does it use?
10W-30
Man I wanna put this in my 47 dodge pick up
How much horsepower can you get out of this motor?? I heard 700 plus
The heads can only flow about 400hp, the bottom end will handle 500hp safely. This engine would be a ticking time bomb at 700hp
Seems like alot of kits, why not just make 2 kits, full on with everything and one without the heads and the intake? as it just seems like doing it this way makes it seem like the customer is getting less for more and its clogging up your catalog and confusing your customers.
agreed
someone is trying to tell me they put this motor in an 86 C4. how can I tell that it is a ZZ4 motor?? he has no reciept !!
Christopher Robin it will have stamp on the engine block “zz4” if you haven’t figured it out already.
86 C4 has a very similar engine in stock form ..the L98. The L98 and ZZ4 have the same cylinder heads, both are roller cam blocks. ZZ4 has a tad more compression. The ZZ4 cam in an L98 would yield a very similar result.
Dear
followers!! Don't let the beautiful pictures confuse you . Anyone who
buys a new car from GENERAL Motors the chance you threw your money into
the trash is very large. In this company there is no customer service,
the company's management does not care at all, if you have a problem or a
malfunction, you can only pray to God there is a chance that the help
will come faster. GM is a very dangerous company, be careful and keep
your money safe.!!!Share so more people don't get screwed.GM is a big bluf

Ugly serpentine set up
What's the time on a track
illest stoner That depends on what you put it in and your setup.
