I'm thinking about adding a little bling to my ZZ4 restomod with C4 suspension. The tranmsmission is a Buick Grand National 2004R.
Question is ....does any one have two fours with an automatic, and does it perform well, bog or other??

If you have two fours with an automatic that performs well, what exactly do you have?

The easiest to get is the Edlebrock set up and it looks great ..as some of our members can testify to.

However I'm concerned about reliable performance first ..then bling, so what are you using?...and what issues did you have to overcome?

Thanks...Stan

Can't comment on the Automatic question.

I've got the Edlebrock Dual Quad setup on a "STOCK" ZZ4 with 5-speed and 3:08 Gear. Two 500 CFM (1000 CFM) is way to much for the L98 heads and cam in the Stock ZZ4. Mine runs better if I just use 1 of the carbs and don't kick the 2nd one in. If I open them both up you can almost see the gas running out of the side exhaust


**NOTE**Mine were added for BLING only and I got a super deal ($600 complete NEW)


Reliable and gets lots of "WOW's"

Thanks for that George..

Of course yours is the one I was thinking about. One of the best looking engines on the forum...and one that sticks in my mind, when I think of dressing the ZZ4.

I wonder if there is some way to set the dual quads up where they are vacuum operated..? I doubt that I could go that route with an automatic if it had a tendancy to flood. There would be no way to rev it up and clear it out...like we had to do the old hot rods when they ran rich.

Maybe an original style system with the wcfb's would work with an automatic...?

Anybody know the answer to that one?

Best regards...Stan

How about a fuel injected ZZ4 - with some bling?

Stan's Customs

Very nice Chris..

I was really wanting a carbed engine because I did so much carburetor work in my shops back the old days. In fact I can do things with a Quadrajet that most folks don't believe...including get good fuel economy. However, so many Q-jets have been installed by amateurs that didn't work well, that they don't have any "wow" factor, if you know what I mean, and why I'm looking at dual quads. I may use one (Q-jet) anyway...just because I can make them haul the mail..and everything else a good carb is supposed to do.

Having said that ..I like your injection set up. Curious to know how the little ZZ4 cam sounds with your injection (one of the reasons I chose an old school ZZ4 instead of an LS)...about the same as carbureted I assume? I know that carb tune can change the sound of the cam a little...

About what was the cost of your set up by the time you gathered everything up?

Also what kind of mileage do you get...with what gear and trans...?

Thanks for the post...Stan

Get a three 2's set up.

Stan's Customs

Hey George, I considered them

...I like them on 348s or late 60's 427's, and 389 GTO's. Just doesn't seem right on a smallblock '61 Corvette to me though..?

Stan - I ran a 3/2 set-up in my '57 Chev with Corvette 365 hp engine -does that count? It might be a good conversation piece in a '61

Stan's Customs

3 deuces on a '57 Chevy seems more period correct "to me" than a '61 Corvette....

Maybe because the hood is taller on a '57 and can take the Stomberg type little chrome scoop breathers (really only had a screen and some mesh in them)

Could just be me though...what do others think??

I have the base ZZ4 in my 65 coupe and have been thinking about the three dueces setup. Anyone using this? How does it work?

Stan,

Again not an automatic, but an OD 4 speed. Runs great with 355 CID and dual 500 cfm Carter AFBs.

I really don't see an issue with an automatic trans vs. the 4 speed (that a little tuning would not fix). The AFBs with the Secondary air valve (Edelbrock AVS) or the Q-jets should offer the tuning capabilities that I would want with an automatic trans.



Note that decent air cleaners can be a bit of a problem with the Offenhauser intake I use (mine shown is a single quad base that I modified into a 2X4). Carb to carb spacing distance is greater than the Edelbrock manifolds, but Edelbrock and Billet Specialties make air cleaners that will fit with the Edelbrock manifold carb spacing. Note also that air cleaners for a 3X2 carb setup is very difficult under a C1 hood (especially if your hood has the underhood cross brace).

Stan,

I would say the cam sounds the same as with a carb setup. As far as the cost, here you go:

TPIS Miniram.....$1200 (new.....cheaper on Ebay)
Powder coat........$ 200
OBD1.................???? I already had it. I was running a TPI setup. You can replace this with a Acel DFI...$1000 or less used
Distributor..........???? already had it
Tranny....Gearstar level 3 700R4 / 4L60 (Lock-up gives me a 5th gear @ 60 mph)
Rear end.......3.54

Mileage is good. I get about 16 in city if I keep my foot off the pedal. I've done a couple 600 mile drives and got about 21 mpg.

I still want to put better heads and a bigger cam in it. Why? because I must have a whole in my head.

The Barry Grant Demon SIXSHOOTER will not fit under Small Block hood. You will need Big Block Hood. These were my 1st choice but went with Dual Quads that fit & much cheaper

Stan's Customs

How much did it like fitting George....if you remember?

My chassis sits the engine 2 inches or so lower than stock.

If you have two more inches, you should be able to fit an Edelbrock tri power in there with a modified air cleaner ~2.5" tall and still not hit the hood brace. You could go a number of ways to get open area and bling. Plasticman's setup or some early/mid 60's Ford setups should give you some good ideas (long and low profile)
My 60" with Edelbrock/Rochester tri power has only ~5/8" diagonal clearance between top of stock air cleaner and the hood brace. Problem is restricted intake due to cleaner short height and element encroaching on front and end carbs. The front edge of front carb air horn is right under the rear slope portion of hood brace.
WOT performance is noticeably better than a 600 cfm Edelbrock 4bbl. Estimates are ~650-750 cfm with the Rochesters.

By the way, the BG/Holley (big block tri power) carb cleaner studs are positioned at the rear of the air horns, as compared to Rochester 2CG center location. At least one restorod C1 is using a modified BB tri power air cleaner.
Looking forward to seeing your end result.

thanks for the post Tom..

You don't have some pics of your engine do you..? I'd like to see the carbs in a Corvette.
