[nidf88]

has anyone put a weber carb on thier 2.8? lmc truck sells a kit with the 38degs. i have a weber on my datsun and i love it. weber vs. holley 2300?
concerning the duraspark conversion... will i notice a difference going with an msd box or digital box from summit?
also does anyone else sell the collar adapter for the pinto distributor other than napa?
BTW thanks to all for all the tech support over the years... without this site/forum i might still be on my 7th A4LD. (converted to FM146 3 years ago)

I got the adapter that goes between the dist. and cap at Carquest for about $10, about any auto parts place should have them, and they can cross the Napa #'s in the tech gallery to theirs. Make sure to check them, my first one was for a V-8 in the V-6 box, it was a special order so I had to send it back and wait a couple days for the right one to come in.

I am using a junkyard duraspark box and the stock coil, it has probably been 2 months and I haven't had a regret yet. I do need to fix the stock carb yet, it is still running really rich as it has for years.

I have never been around MSD, a digital box or a weber carburator so I can't say anything about them.

Not from experience, but an opinion.
I don't think you are going to get anymore power or help with the Weber. They are good carbs but they are expensive. I used to work on the Weber/Holley that were used on Pintos for years. Good carbs, but not a whole lot better than a regular Holley in m y opinion. The Webers I just looked at on the web are for off road use only and that can be a problem on the street.

You may have linkage and air cleaner problems too.

Sorry I can't give a better answer, but I guess this is better than nothing.

LMC is great and all but they want $699 for the kit. Carburetion.com has the kit (K457) for $429. I found a couple other vendors online ranging from $475 to $510.

The only alternatives I've found are to raid a Pinto 2.8 V6 for the intake, carb, distributor, wiring, controller, etc or try to DIY with a new carb (from whatever source) and a new HEI-based distributor. Problem is I have gotten zero response from the Pinto community in looking for these parts. I am going to try the JY, to see if they even have a Pinto, other than it's new (read: expensive) parts or no conversion.

Also, I was curious about this "collar adapter"?

The coller is just a cone shaped adapter that goes between the distributer cap and the distributer. To run the system the only thing you really need from the junkyard is the harness to connect the box, coil and distributer, and if you are feeling lucky you can nab the box too. I got my harness off of the shot 1980 400 we have sitting around, the box came off of a old F-150 at a JY. A rebuilt distributer was about $70 (they took my old one for a $7 core too ), the cap and coller were about $10 apeice, and the rotor was probably about $5 at most. For just the distributer side of it was just shy of $100 for everything touching the distributer being new. I tried finding used stuff too, but most Pinto's died decades ago, so I just went with new.

You can do the metering block mod to your stock carb and run it, I am going to do that as soon as I find a chunk of plastic that is 1/2" thick.

thanks! autozone has the collar. cap, and button. metering block? sounds like to much work. looks like i just need to flip a coin for the carb selection. for the ignition box... i guess a better question would be is there a down side with goin msd? I probably wont even be able to tell a difference, right? at least i will be getting rid of all the emissions bs.

Here is the metering block how to:

It looks pretty easy so I might try this because I think my carb is in GC, I just do not want all of the emissions crap on the engine.

Durr.... I'm an idiot. The PN's were in the Tech Section.
Do you have PN's on the adapter / collar, distributor, cap, and rotor, and / or the model and year of car you were looking under? I'd like to go ahead and get all the parts from NAPA if the JY doesn't have anything.

I've heard that you ask for a 78 Pinto but there are two distributors (I think a single advance and a dual advance?). Just want to make sure I am looking for the right stuff.

Weber

I have a little experience with weber carbs, it was on a turbocharged KZ1000 engine in a mini sandrail (sand Bullit).
This is what I have gatherd with experience and hearsay! Hard to tune, lots of time, money and energy. Don't work to good off road...Maybe fuel slosh? I'm waiting for my Holley 350 DS and MSD to get hear. I have always used MSD and do notice a difference.
My advice is a holley 350 and off-road needle and seat.

Good luck! I will let you know how it runs.

I gave the Carquest guy the following #'s and told him it was a for a '79 Pinto. These #'s are in the 2.8 section of the Tech Library. I have the Carquest #'s in the truck, I won't see it again until next weekend.
