I have a 78 IH Scout, 304, v8, auto. I installed an efi kit from affordable fuel injection. Five chips later, and still not right. The distributor base plate has bad mount, its was machined poorly. Does anyone have any suggestions on a dist. And coil to run with this efi? As far as the chip, I am taking it to a friend and they will tune it on their dyno and burn new chip.
Thank you,

Jessica,
there's a couple options.
On the binderplanet I have a link to jamar that will cut the top off a TBI distr and mount it on an IH Holley distr. About $140 when you send him the dist's.
This gives you a distr similar to the factory GM.
I also run the Holley distr converted to the Ford duraspark pick up.

As for coil.
I personally only run the GM TBI coil.
They have done fine.
I try to keep most things factory and plug and play.
Because I normally deal in owner conversions, the simpler the better.
 
One problem, the GM type has a ( vacuum advance ) that controls the timing advancement (ie; o degrees at idle - maybe 10 degrees at 2000 rpm). On the efi system I put in my Scout, it has the timing controlled by the ECM (computer ). So do you/they delete the vac advance or loop the computer wire that controls the advance?

Jessica,

is your Dad's name dave? Didn't I meet you guys last year at the nat's? If so please contact me and I will try to have afi send you a replacement distributor. I also had an experience with one of their distributors doing the same thing a while back so afi now uses the same distributor as what bill is suggesting.
 
I run a pieced together GM TBI from several 88-92 Chevy trucks on my 345. Modified stock GM harness, stock 5.7l ECM, late 90's Ford fuel pump, GM 8 pin module, GM TBI coil, and my IH Holley dissy w/ Ford duraspark guts. I don't have a knock sensor or speed sensor. Never got around to using winaldl or having a chip burned, it runs great and never misses a beat. Been running it for about 2 years with no issues. I don't expect I'll ever feel the need to have a chip burned as long as it keeps running as well as it does. The only reason I May get a chip burned would be to make the idiot light go off. :cornut:
