Thread: H.E.I. distributor from chevy to 230 6cyl

    The pics are not in order, but you get the idea. First determine were the HEI shaft needs to be cut to mate up with the joint on the original distributor. The length is important, you don't want it too long it will bind, and too short it may pop out or wear on the end of the shaft. Cut the HEI and drill a hole for the roll pin and put it back together. Unfortunatly the pickup coil was shot when I got it back together(had lent it to a friend to try few years ago), and due to 3rd cutting of hay and a lot of grain to haul I bought an HEI that was advertised on the site, my father wanted it out of the shop, anyway. Otherwise the fuel/vacum pump most be removed, and you cann't use the original timing. It starts right up and idles great, I have a 2 barrel on it and I have no complaints.

    I hope this helps.

    In my Jeep CJ7 I have the original 258 straight six and I used a GM 250 straight six HEI in it. The only mod that has to be done is use a distributor gear from a 360 AMC V8 since the gear on the chevy is reverse cut.

    If you look for a 1977-1978 truck with the six in it, you may find that the distributor cap does not have the coil on it. This may be better or worse, depending on if you want a separate coil. These are still HEI. I have not seen any of these, but they are out there.

    For a 258...or a 232 I would assume...that may be true...the 230 is different...just so no one confuese your tech with something for the 230...the 230 has a flat blade screwdriver type tip instead of a gear...

    5 mpg? are you sure your fuel pump is not leaking into the crackcase? i second the other member go with the pertronix ignitor it replaces the points and condenser and fits under the stock cap, easy starting and no hesitation through the power range and does not require new plug wires. I have one on my M37 and it starts no matter what the weather is cold, hot, dry, wet even if the truck is hot or stone cold she fires right off every time I believe it was a part # MV161 or 151 I can't remember but it's easy to find.

    I dont see the xact one needed on the pertronix website...the civvy distributor is a Prestolite IAT4416 and the military one is a Prestolite IAT4411 4AT.

    I am unsure if the civvy unit fits the mil housing...but I know the converson has been done on the civvy types...

    Price looks to be around $200...little less maybe..

    Heres a thread with a little more info:

    I bought a 67 M725 in 2008, previous owner had installed a HEI distributor.... didn't really do a great job about it. It's functional. Oh yeah, my M725 gets 6.3 miles to a gallon with no leaks.... and a strong tail wind!

    I've never heard anyone really talk about fuel mileage on a stock 230 tornado. My truck is pretty close to being stock, exception being the 1100x16 Michelins. When i checked gas mileage last summer it was 5 and 1/2 mpg! Alittle disappointing, but I wasn't expecting a whole lot more than that. I've since changed out the plugs and wires and went to about 6 mpg. A 6k truck with tall gears and the aerodynamics of a barn door just isn't going to do much better. When fuel got low in the Army, we just drove them to the nearest fuel truck and filled them up. I'd love to do better, but I do not use mine as a daily driver, so it's not to much of a concern for me. With the price of gas going up daily it will be alittle more disappointing, but I figure it's a small price to pay to own a piece of military history.
