dual carb kits.

Heh, single inlet port and a two barrel carb, that is as funny sounding as a 4 barrel on anything but a 61 for pickup

Yeah, I have never seen dual IDF's for single port heads, but hypothetically speaking...

As for Kads, I am speaking purely on my own experience. Granted, the set I was dealing with was ancient. They ran smooth as silk. Perhaps the quality has gone down since that set.

Ed: Kadron USED to make a nice carb, but the linkage has always sucked (get GBE linkage to solve that problem). Newer Kadrons have gone downhill fast, and sometimes are junk brand new out of the box.

Take you chances!

Hopefully nobody.

To return to the focus of ZionVier's orginal question. He has a stock single port 1600 and not much money.

So what should he do assuming he can come up with say $300 or so to get a bit more power?

I'm wondering if a nice pair of Baby Dells wouldn't be good for him? And what about the exhaust?

I saw a '70 Ghia last year with a single port engine running dual progressives. The guy had fabbed the manifolds himself. I didn't get to speak with him as they had just finished putting the straight jacket on him and were taking him away...

Again, based on personal experience, baby Dels ran poorly for me. However, in their defense, It's been a while, but I don't recall that this particular set had a balance tube... They did include a more reliable hex bar linkage. I have spoke with several people that have run them successfully.

An extractor type exhaust that fits on the heater boxes or j-tubes will help a bit. I like single or dual quiet packs for this, they are free flowing, but you can still hear yourself think. I would avoid the four-tip Monza style, they don't have equal length tubes or the extraction gained from a collector.

Another option to boost power a bit would be to go with ratio rockers.

i have heard a lot about kadrons, but i don't like them cause they are made in Brazil. my friend is using a pair of 36 Dells with great success(in fact better than Solex) honest, i have seen this myself. idles at 850rpm!! the old webers are better i think because they are made in the good old Italy...the new ones are quite crude because they are made in Spain, ...i have seen it and compared them myself so i think i should be correct...scout around for used Dells...they are good carbs, buy and keep some spares like diaphragms, gasket set etcetc. somehow i am quite fussy about the country where the product is made ......

Well, after reading all your comments I have come up with a few things. One, I will be changing my heads to convert to a dual port. As for what carbs to get, I definately will not be going with a set of Kadrons. The main reason, I'll be increasing the size of the engine in about a year and would like to be able to reuse whatever carbs I will get. I will will start pricing around for a set of 40s. I only plan on going up to about a 1776cc engine, so 44s still wouldn't be needed. Perhaps if I happen to hit the lottery, or just get hit, I'll get enough money to build a 2L Type 4 engine and end up in "The Type 4rum". Until then, and until I learn more about engines, I will find a set of dual port heads and some dual carbs and be happy with not having only the stock 57Hp.

I do have another question though... what does IDF and IDA stand for?

And by the way... just so you know, I do have that monza style exhaust on it. I liked the deep low volume tone that it makes. Is there something else that makes relatively the same tone but gives more power?

Header with single quiet pack will give you a few more ponies than the dreaded monza. If you don't need heat, go to a merged system. If you want better sound, go with the header and a dynomax or similar muffler. I like my Kadrons, but they are OLD, metal fuel lines and breather hose fitting on the air cleaner, air filters even say Kadron on the rubber part, and I got them used for $100. Once I get my 40IDF's rebuilt I will probably switch though, more tunable.

That was for my 1600 by the way, DCNF's are coming soon for the 1835. Did you get my check yet John?

check showed up today!

If you find a set of the old style Kadrons, with the metal "T' fitting and fuel lines, rebuild them, get the throttle shafts re-bushed, and get the Berg linkage, you will have a good set of entry-level dual carbs, for not much money, depending on how good your garage sale/swap meet skills are. I even have some of the old single port intake manifolds for them, some are aluminim ( 2 pieces with seperate balance tube) and one piece with a metal balance tube running between the manifolds.

Tate · Post by **Tate** » Wed Jul 25, 2001 9:13 pm

Mine are definitely old, metal t and lines, air cleaner tops say Kadron and are painted silver, not chromed, at least I think it is paint. Has the perforated metal housings around the filters too. Intakes were welded steel, replaced them with aluminum ones and then had to shorten the linkage. I am not willing right now to spend more on the Berg linkage than I spent for carbs. When did they stop making them with the metal fuel lines? I like the way it kinks around the coil.

Years ago when the dp first came out we found out what works and what don't work on a stock 1600.This recipe got a stock '71 sedan with about 6000 miles from a pure stock 20.42 to a very low 17... number 1 a good tune up. this aolone was good for a tenth even on a near new car...playing with timing and plug gaps and launch along with jetting was good for a nother tenth or two...,aircleaner ? yeah a bit not worth the possible cosequences....extreactor .38 this with the old glasspack....a newer design shold do beter 1.4 empis got a low 19.... a single old dcn or similar along with a different dist setup,think it was bob's old Mr gasket ? made a good difference and the car was running very low 18.a little tweaking with timming ,launch etc and Bob had a mid sixteen car with a stinger no fan belt and a lot of seat time. (And one seat!)~A switch toa power pulley lost two tenths returning to a stock pulley and a stock belt plus great air returned a 16.92 with removal of the spare and jack. As the miles acumulated the car slowed down and at 12k a mild port job and 8.5 c/r and the above mods except for a switch toi dual 42 webers got the car to run a best of 16.02 with the stock pulley and a muffler.so don't dispair those little 1600s can run tough...have fun

I think my next move for the 1600 will be 1.4 rockers, a cdi ingnition to replace the 009, then replace the Kad's with the IDF's. I don't want to tear into the motor until it needs it, this is my most reliable daily transport. Plus I need to spend some money on the suspension, 28 year old oil shocks are not good for the highway, lol.
