HEI Distributor
I have a 1989 Pontiac Trans Am with the 305 TPI. Right now I have the stock distributor, but I have found a really cheap HEI one for sale on Ebay. I was wondering if the swap can be done quick and easy...?
Thanks.
Thanks.

Re: HEI Distributor
If your asking if a hei divorced coil can be swapped out for a ccc , early tbi trucks,tpi 85-86 f-body, 85-91 corvette coil in cap yes. The connecter for the dist reference , est, flat 4 is different but you can easily install a packard/delphi weather pack connecter. The dist power and tach you can buy the pigtails or use female spade connecters. To make it correct the spark Latency in the tune is different but it will still work.

Re: HEI Distributor
I ordered the distributor with the in cap coil, because I need a new one and it was the only ones coming up when I put in HEI. But are the plugs put on the exact same? Like in the same order and prongs?
Thanks.
Thanks.

Re: HEI Distributor
The pinout of the icm is different IIRC the order of 2 are swapped.
dist ref high -ppl/wht
dist ref lo -blk/red
est bypass -tan/blk
est control -white
Early years coil in cap computer controlled hei's had different colors for the icm lead.
If your unsure the origin of the distributor or cant tell the difference from a melonized gear you should purchase a gm 10456413 .

Re: HEI Distributor
My new distributor looks like this one, but it has a black cap. It is rated at 50k.
But my stock one doesn't have the advanced vacuum thing on the side, how and where should I hook that up?
And my stock one is one without the coil in the cap, the new one has he coil in the cap. The new cap is a inch to two inches bigger, is that just because of the coil needing room? And is that going to be a problem?
Thanks again.

Re: HEI Distributor
The only reason I was asking was because I really need a new one, but if its not a good idea...then I will pay to send it back and find a different one. I just had no clue that it wasn't for my engine. Thanks for the help.

Re: HEI Distributor
Can you send me a link to one of them? I can't seem to find one for a TPI. Thanks.

You might want to run a melonized gear or look for one off at leter vette.
Gm 10456413
