Inliners International Forums General Discussion Engines holley weber vs stock 2 barrell super 6

so what do ya guys think about this problem, like I stated in an earlier post that I am going tol buy one of these for a friend and I am stuck in the middle on whether to buy a H/W and put it on the super six intake, or use the stock as a rock two barrel that comes with it. What I need to know is how good is the stock two barrel, does anyone know the CFM's on them? and would a progressive HW be better than the synchronous 2 barrel, or is there no major advantage in this set up? I know that if I use the HW then I have to fab the cable, and that looks like a bear, can you imagine it "merry christmas....you just need to fab a pull type set up for it to work, see ya later!!!" I tried to get some help from the mopar forum but could not get one hit, I did call tom langdon, and this is the info he gave me, so is the advantage (if there is one) worth all of the trouble to put a HW on there or should i just rebuild the stock 2 barrel, thanks guys!!!

The need for a "progressive" two-barrel came from the high revving four-cylinder Japanese engines (i.e Toyota 2-TC 96 CID with redline of 7000). A significant amount of air needed at 7000, but very little needed at idle and off-idle. A conventional two-barrel with sufficient airflow to meet the 7000 RPM requirement was too large for sufficient air velocity at low RPM's, hence the progressive two-barrel.

The American manufacturers also used these progressive two-barrels (notably Pintos, Vegas, four-cylinder Chryslers). These carbs were surplused during the early ??? mid ??? 1980's. We could have bought a semi-truck load new at $5.00 per carburetor. Due to the price, we did a lot of experimentation and testing with these at that time, but were unable to make them perform as well on larger engines (ie Chevy 216, 235) as the stock carburetors.

The only real benefit we could see was cost. Due to our inability to make them perform as well as original units, we only bought the one we used for testing.

I understand from reading these forums that others are using them, and seem pleased with the results.

It would be interesting to see some testing of these compared to good originals.

One reason many aftermarket products get rave reviews is that most are sold when the original being replaced is in need of work. Often, comparing an unworn anything to a worn-out original gives a less than favorable comparison for the worn-out original.

debane261,

Go on the www.p15-D24.com (MOPAR) web site forum there is some nice pictures of a flathead 6 with 2 holley weber carbs and the linkage set up. Really not that hard to set up a pull cable for throttle. E-mail the guy maybe he can give you the lokar part number. Good luck.

all that is holding me back is the cable set up idea, will this hook to his stock pedal or would the pedal need to be changed? I know you can buy things like this at the local parts store, the cable that is, and you could probably pirate an edelbrock bracket or something, but all I am really worried about is if the stock pedal can be used so that no major mods would need to be done to his pedals, because if they do, probably better off getting the stock 2 barrel and linkage with, so a HW wont make more HP and better gas mileage then?

Im running two of these on my 261 supplied by Langdon's Stovebolt. Tom puts together a very nice package of linkage, adaptors and air cleaners at a very reasonable price, give him a call.

yeah I have called tom and he tells me that these linkage packs are for the 235/261, and thats all, looks like I would have to build my own which is what brings me to the issue of whether I can use the stock pedalr set up for his car or whether it would have to be removed and a new one added, if this be the case it is probably better to not go that route (more cost effective for the return on the investment, I.E. better HP and mileage) toms set up is a bar linkage with rods and what not which wont work on a 225 slant six ya see, so it would have to be a pull type cable set up, any other help here would be greatly heeded!!
