SINGLE FOUR Barrel

This is most likely your best bet for reliability, performance, and cruiseability. They are easy to maintain, and you can expect good gas mileage as well as low maintenence. For performance, the single four barrel is tough to beat! Especially if you opt for the exotic intakes.

DeMon Single Four Barrel
If you are serious about high performance street-strip induction, the Speed DeMon carb will fit your needs. It features four corner idle, double pumpers, and billit metering blocks. It also has a very smooth and stream-line finish for a professional, clean appearance. If you opt for all-out performance, you will find the Demon carb (with the correct intake) will easily out run any two four setup available today. It comes at a price though. They are about double the price of a standard street carb, but the same price as a Holley Professional Racing carb. So check it out, you won't be disappointed!

Holley DOMINATOR
This is without question the hottest drag racing carb on the market. The CFM rating is larger than the "traditional" two four tunnel ram! While you can get an adapter to connect the Dominator to a "regular" intake, I wouldn't recommend it. Dominator intakes are specially suited to utilize the Dominators unique racing characteristics. So if you are looking for a RADICAL street setup, this monster will fill the bill. And, you will experience "sticker Shock" when you see how much this baby costs.... There are optional velocity stacks for the Dominator and they really look great!

Two Four Barrels on a low-rise intake

The "in-line low-rise 2 fours" (AKA: Dual Quads) is as nostalgic as you can get for the early to mid 60's. They are still popular and reasonably easy to find. The earliest Chevy 2/4's had Rochester carbs then later moved up to Carter AFB's. Some Ford engines were equipped with Holleys and Autolite Carbs. These setups are not too difficult to work with, and can be very reliable but definitely more trouble than the single four. They look very impressive for that nostalgic look.

2/4's on tunnel ram

The look of 2 fours with velocity stacks hung way up in the air on a polished intake is awesome. But this setup is painfully difficult to make streetable. These manifolds were not designed nor intended to be used for street driving. Proper carb selection, jetting and tuneup is your only chance to make the tunnel ram street worthy. It can, and has been done. To get maximum streetability I would recommend your getting the smallest four barrels available IE: Holley 390CFM or Holley 450CFM carbs. These will just barely make your setup streetable, anything bigger will kill your chances of good bottom end drivability. The trick to making this setup work is to "drive" lean but "dump" huge amounts of fuel when you accellerate. A lot of experememtation is required.

Tuned Port Injection

This is new technology, requiring sensors, computer and high pressure fuel pump to operate. But it's worth the trouble. Because the computer controlled environmental air/fuel mixing you get optimum performance regardless of RPM. They have a real high-tech look that is second to none. TPI is relatively expensive, and sort of a pain to install and setup but well worth your trouble!

2/4 Street tunnel ram (not pictured)

These induction systems look fairly cool but are troublesome. The manifolds are built in 2 pieces, a bottom which is bolted through the inside of the intake to the heads, and the top which supports the carbs. The gasket which seals the top to the bottom is very large and nortorious for blownig out, and leaking. Because the carbs are side by side, unique linkage is needed for coupling them. Street tunnel rams are more mid to upper end setups, making them more streetable than the traditional "tall" tunnel ram but not as impressive looking.

Blowers w/carbs

This is by far the most impressive setup. An added benefit to the blower setup is, they are very streetable (if you don't get too carried away with the over drive). Blower setups don't require fancy cams or heads to produce massive horsepower. Not only do you get super impressive looks, lots of horsepower, but you also get the "blower sound" which is unique to only the blower. They are commonly expensive but not that much more than a good TPI setup. So if you are looking at getting a Tune Port Injection system I would consider moving up to a 6/71 blower. The blower is easier to install and configure.

3 deuces

You can't get any more nostalgic than this! The grand daddy of hotrod induction! They are still popular, and very sought after setups. The older "3 deuces" were replaced by the "Tri-power" and the "six-pack" label in the 60's and early 70's. Virtually all OEM 3 deuce setups utilized progressive linkage. Where the center carb carried the idle circuit and the other two carbs opened at some pre-determined point. The performance of the "newer" 3 deuce setup is good, and reasonably easy to tune. If you like the nostalgic look and want a reliable setup to boot, this is the way to go. Do not under estimate the performance of 3 deuces! The combined CFM is about 900+ and can deliver an excellent power band!

Hilborn Injection

As fuel injection goes, this is nostalgic. It isn't very streetable, it needs constant tuning, but radical looking with 6" chrome stacks. These setups only know one mode; wide open. They will idle, but anything between idle and wide open is terrible. If you want this type of look then consider Webers or Delortos.

Weber Carbs (not pictured)

Down draft Webers look very similar to Hilborn Injectors with cool looking 2x2 velocity stacks. When Webers work, they work very well. The performance falls short of a top of the line single four barrel. (Which is very strong) There is a lot of linkage to contend with and lots of synchronizing involved in getting webers reliable. This setup is expensive (around what a blower costs) and rare. If you are looking for that "stand alone look, and don't mind frequent tuning" this is your baby... You may also want to consider Solex and Zeneth carbs as an alternate.

Delorto Carbs (not pictured)

These are similar to Webers, except more popular in the side draft setup than the Webers. These are very exotic "Itialian" carbs mostly found on Ferrari's and Lamborghini's. You may also want to consider Solex and Zeneth carbs as an alternate.

Rochester Quadra-Jet (not pictured)
Very few people have considered the Q-Jet as their induction system of choice. It's a shame, because it really is an excellent carb. In fact, Rochester pioneered the "spread bore" technology! The idea was to make carb that cruised economically but provided awesome power when the "big bores" opened. GM used the Q-Jet on virtually every big engine they built that included a four barrel, with the exception of a few Chevy big blocks. Q-Jets aren't very pretty to look at, but will give you good performance, good economy, and they are reliable. Although I've never seen a Q-Jet dual quad I bet they'd would work well.

Also, be sure to visit the BBS. We have many experienced T Bucket owners there, which
would be glad to answer your questions about their induction systems!!
