I burned up my points and was to cheap to go into town for a new set. I found that the distributers for the 304 and chevy V-8 a practicaly the same. Now what I am wondering about is can a person take the electronics out of the chevy dist. and graft them into the international? Unfortunatly I do not have a elictronic dist. here to look at to see if this is possible. Does any one have some input on this? I know every one here has got something to say good or bad so have at it. :D

I've hear of people modifying the Chevy dist shaft to fit IH.

I seen here or someplace someone who had machined a distributor housing for a GM HEI to fit a SV motor and control the advance for his Pro-jection

eh I think :rasta:

Just get a aftermarket electronic setup like a MSD or Jacobs and keep the points. I've run both these setups for years without a single problem. Havn't changed the points on the MSD in like 5 years and it still runs great.
Just a idea.:)

Yeah, you more or less have to lengthen the shaft of the GM HEI distributor and use the IH drive gear. There is a guy who has done a couple of these, but if you're too cheap to drive into town for a set of points, then you're definately too cheap to shell out the $200 bucks for the modified GM dist...

I did get new points just not that day. I guess I should of said that I didn't feel like a trip to town for just one thing. You did not understand the question I want to modify the IH dist by using the parts out of the chevy dist.

It would probably be easiest if you just found one of the IH standard-issue DELCO "window" distributors.. :D

I'm planning on using the Mallory dual point dist with Pertronics module and light it up with a Crane ignition and coil.

I'll keep the points in the glove box just in case.

Is this what your looking for?

Guy out of Colorado does the mods, search on Binder for the contact info.

Then jdjanda posts a picture of the modified GM HEI that I described my reply, and you say:

Make up your damn mind. BTW that dist. in the picture is NOT an IH distributor modified with HEI parts. It is an HEI distributor with a billet housing extention, a lengthened shaft, and an IH drive gear.:rolleyes: :rolleyes: :rolleyes:

O.K. so I made a mistake. I couldn't tell the difference in the distributers by the picture. I also have the right to change my mind. If it appears that one will be easier to set up than another. I do not want to get in a pissing match with anyone about a picture or anything else for that matter. I am here to learn what I can and maybe help someone else out if possible. If you do want to get in to it we should take it to the general chit chat and leave the tech section for tech.

D.U.I. davis unified ignition will build you one complete for an IH that will hook up and enable GM spark control on the Holley projection system for about 500bucks

thats the only reason I could see going to the GM hei.

I'd do as someone above said and get a msd or jacobs

I run a jacobs in mine using a set of points to supply the ground square wave needed to trigger the jacobs brain box.

because there is no charge going through the points they will last a really long time and they have no needed gap setting or dwell as long as they open and close.

they also are not sensative to small amounts of moisture as they are when you are using them to time the saturation of a coil.

the jacobs is awsome IMHO...best mod I ever put on an IH motor

More info please! I cann't see paying 2x the $ for a Jacobs over a MSD. What makes the Jacobs worth the big bucks?

*shrug*

I run the Pertronix Ignitor (from SSS) in all of my rigs with Points distributors.

Seems to work just fine and trouble free.

Good to 6000rpm.

I'd like to go to an MSD for the low-rpm extra-spark on my trail rig, and something like an MSD on my racer 1) to see if it'll really help (thus far the Pertronix, stock coil, 7mm Belden wires, and .030 gapped Autolite 85s with the NAPA Lifetime starter have no problem cranking over the 10.25:1 304 (with 25+deg static advance) or firing it at 5300rpm).. and 2) I want some of the add-on goodies for the MSD. Push-button timing retard (hit the NOS and retard the timing), rev limiter, etc.

I met dr jacobs at a volvo seminar years and years ago

hi is a super smart guy...holds hundreds of patents

he invented the first heart pacemaker as an example

he was hired by the mexican goverment to creats a ignition system that would reduce emmisions around mexico city

his first system is the basis for what they sell today

he has a patent on the way it works

It uses a microprocessor to measure the resistance across the sparkplug gap. as the piston comes up and compresses the gas/air mix the resistance across the plug goes up as well

the unit then takes this information and increases or decreasee the amount of the coil discharge voltage to match the need in that perticulier cylinder.

it important not to over power the spark or the flame front will advance/burn to fast dropping the effieciency of that powerstroke

the msd in MSD stands for multi spark discharge. it works by using multiple discharges to keep burning that left over unburned fuel from the first flame front. because most "gas" burns best/makes the most power near a 14 to1 air to fuel ratio the second spark discharge is never as efficient as the first. after that its all about reducing un burnt hydrocarbons not more power.

doctor jacobs also invented a plasma ignition that uses no spark plugs...it was purchased by ford I believe back in 1989 or so ...why we havent seen it in production god only knows. it was getting 28 to 30 MPG in old 350chevy caprice taxies on crappy mexican gas with almost no emmisions.

my scout goes right through emmissions with my jacobs system with no cat in the exhaust!!

Illinois has a no look till you fail the second time policy, I know of a dozen guys that after failing big time bolted on a jacobs and passed easy.

I have also had jacobs systems on a friends chassis Dyno on a number of different makes and models. from old BMW's and Volvos to hot rods and 4 x4 trucks,and the claims they make in there ads are very true .

I'm trying to figure out how to get one on my shitty MPG rover as I speak!

forgot to say Jacobs gives you a set of liftime warrenty wires with the purchase of there system

they are really nice wires to.

one goes bad ...measure it tell them what kinda ends it has...they send you a new one

sent the whole set back once because a few where testing a lttle high in resistance(after 5 years) they sent me a whole new set cut to the custom lengths of my old ones

I went to time my 345. it timed to spec at 800RPM, but as the RMPs went up, the timing would get farther out of spec, like 5 degrees.

Does this sound like weak springs? If so should I just replace with stock, or is there a better set to get.

It also knocks like hell under hard excelleration, but the Qjet isn't dialed in yet.

if the advance comes right in off idle with the vacume advance disconected and pluged it could be.

the springs I have had the best luck with are yellow and where numbered as #16 spring...what the 16 stands for? i dont know

the ones that came in the rebuilds are painted red and the advance comes in a little sooner.

the knock could sure mean you have to much total advance(crank+diaphram+mechanical)

I'll call my buddie the dyno guru and get the low down on what the numbers mean and if they are standard across different brands

That guy (the one in Pueblo) died. The lady who now has his old p[hone number gets REAL pissed when you call and ask for him. Tera-izer even went by his old place and it was vacant.:(

I'm actually building them now - I've got one in my Travelall (HEI made to fit 345 and 392 engines). I get 14 MPG most of the time (driving agressively).

Anyway I've got two in the works right now. Let me know if anyone is interested.
