engine tuning
#121
Well went back at it again today...changed springs to 1 heavy and 1 medium....inital at 12 deg and still getting engine ping......tried it with the vac-advance plugged...and still no good!!!
Im starting to think my engine is higher compression than we calculated....I think my next step will be to try a few gallons of 110 race fuel mixed with 91 oct pump gas.
I called a hot rod shop/engine shop and cant get the car in till after june

Well here is the latest.....I put 20 litres of race fuel..110 oct...cost me $80 It helped quite a bit!!
Im starting to wonder if the old cam that I took out had more performance than my new one!!
I also picked up a new HEI distributor/cap/coil/rotor.....see if it helps....any step by step instruction how to wire this
Thanks guys for all help so far!!!

It's pretty easy, the coil is under the top of the cap, once you take the cover off the old one you'll see how it goes together.
Where is your total timing now? What you may need to do is install a stop to limit the amount of mechanical advance to allow you to get more initial.

I don't already have a hei......I have a petronix electronic ignition with a msd coil!!
right now I have the red wire from old distributor going to the positive site of the msd coil and a yellow wire(starter wire???) and a black wire???
I think my tach wire goes to ground on the old coil
I will have to remove the old coil..I know that because the new distributor HEI distributor/cap/coil
So the new coil has a red/black/yellow wires......so do I just connect yellow to yellow........red to12volt ignition......and black to a ground????
And where would I wire my tach wire to??
This will be my first time installing a HEI so stay with me here...lol

It's not that hard. With an hei it's just a batt. wire. Non resistor wire! lol Depending on if you ran your current dist. through the resistor wire You may not be able to use it because hei needs 12v all the time. Most point dist. voltage dropped after some run time. So find a key sourced 12v hot when the key is on and hook it up to that. That's pretty much it.

So copper are you saying I can omit all the wires to the old coil.......and just
1. run a hot(12 volt) off the ignition to the new red coil wire
2. new coil black wire to ground???
3. what about the yellow wire on the new coil????
when it comes to electrical im as dumb as a rock
#128
The coil is on the cap and is prewired. All you have to do is provide the power source. I am running mine off the firewall junctionbox. That is hot all the time but I have it on a switch and doubles up as anti theft.

Make sure you find a 12v source that's hot not only during key on engine off, but also during cranking. Windshield wiper type circuits will turn off when the key is in the cranking mode but be hot when it's just in the key on position.
And the voltage drop the Mr. Incomplete mentioned is because of two different wires running to the old points style distributor. One is active only during cranking and supplies a full 12v. The other is active during running and supplies approx 9v. That helps prolong the life of the points and condensor. HEI's need a full 12v all the time.
Hope this helps.

Bullcrap, quit trying to justify your incomplete, off the cuff answers. You're wrong and obviously a bit of a hack, plain and simple.

Calm down gramps I never said I was right or wrong. Again sometimes explaining in fine detail confuses people. He already mentioned this is not his are of strength. I think eric explained it very well. And yes I know how to do this too. Sorry if you feel I'm a hack. Hack or not I have had much better sucess than many many many other people so I must be doing something right considering I also spend a lot less money too.

Bahahaha that's so stereo typical. Haven't been called a punk in a long time. It's been proven if you relax you live longer. The icing on the cake would have been the "back in my day" line. Quit getting your depends up in a bunch over nothing.

Haha...thanks Eric and all others for the help.....I noticed last evening that napa sold me the wrong coil cover!!!
As for the bickering.....just sing together now "why cant we be friends"
Cheers guys and be good to one another.

He tried the 110 and it did something. Compared to everything else. I just don't get it only mark jim and nick give me crap. I guess some people just really dislike me enough to try to knock me down a peg which is fine but again ., half assed answers or not if someone cared enough for my help they would ask more if they felt I was unclear much like shcool. The teacher will tell you something if you don't get it you ask a question and then go into further detail. I'm young enough to remember school. Even when I was in m vo tech program. When they teach you on how to bump metal they show you the simplest quickest way on how to hammer and dolly a dent out if you don't understand why at that point you ask how or why the position of the dolly matters a lot. Which I have to explain to my apprentice things every day. I give him the basics if he is having a hard time he ask's me then I go into detail. Again halfazzed to you not to the op. Whose thread is this. Not yours so why do you care. It's up to the op who's advice he runs with or who he decides to ask what what is. You obviously have an ego problem where you have to publicly have to give me crap. You did pm me about it but it seems this is a personal issue with you not anyone else ., oh yeah jim too same issue with you two guys.

Just a little update...I drove the car to A&W to get some dinner and after I got home I removed the old coil and attempted to remove the old distributor....**** it was too hotlol. will wait till tomorrow evening.
So here is another question.....I looked on the fuse block for the igniton terminal and I already have some things one it(my lights to my rpm/oil/coolant gauges) Can I still add a wire to this with all the others for my 12 volt power to the coil????

I am glad the fuel has made a difference and soon you should have that timing problem nipped in the bud, plus any carb adjustments then you should be smokin those tires soon!! On the fuse box I try not to over load any terminals too much might check for another terminal with a constant 12volts.
#142
I'm hoping this does it for ya Scooter. If you don't have a resistor wire to start with then you can just simply transfer the connection from the old coil+ to the HEI BATT. Just put a 1/4 in female spade terminal on the 2wires and your done. If you did have a resistor wire in there (I did not read back thru the thread to check, but I thought we covered that), that might of been your problem with the old distributor.
#143
Another update....today I got the cover for the coil cap.....but it didn't come with any screws anyone know what size screws that would the coil cap???
I also now noticed with the new distributor cap my old 8.5 MSD wires don't fit this cap right....****...****...**** If its one thing its something else
Is there some way to re-use my old wires...new ends????
On a brighter note I got it wired to the ign on the fuse block with 12 gauge wire!!
Here is a pic of what was going to my old coil on the positive side which I have now taped up...hope its ok.

also in the coil instructions it mentions something about a secondary ground....I just grounded the coil with the coil screw..is this ok

http://jandssafeguard.com/safeguard.html Anyone tried this for knock control?
I have one that I have not installed yet as a last resort. Im going to try dialing in my 455 a little better first as Im having similar issues as Scooter123 when I try and boot it. I was also thinking of dumping my HEI for a MSD 8529 Distributor. Thoughts anyone on these ideas?

Yes you can change the ends on your wires but HEI's like a spiral wound wire. I use Taylor Spiro Pro 8mm, plugs gapped @ .045.

Hey Scooter, remember way back when I asked this question? I think that tan wire you posted a pic of previously is the resistor wire that should not have been there to start with. This might have been what was causing your problem all along.

Scotty, that's a very good distributor, have not heard any complaints. Just follow the instructions. As far as the knock sensor system, I would think it would work fine and seems simple enough to hookup.
#148
What are the black and tan wires in the picture.
#151
The tan wire is actually yellow, and goes to the starter solenoid.
That is the original factory arrangement and terminal end.

Scotty, that box will make scooters problem worse, when it detects ping it puts a delay in the timing signal. We need to get his problem corrected.
#154
Yes. That's what people have been telling you.
Tape these off and run a wire straight from a 12V source.
I prefer the heavy pink wire from the ignition switch, but a terminal plugged into the IGN tap on the fuse block will work, too.
I really think it's yellow.
Scooter, is there any way you could give the "tan" wire a good rub with lacquer thinner to clean it up a bit, then post another pic?
Also, is there any way you could post a macro pic of the terminal end itself, showing the way that the black and "tan" wires are crimped to the terminal?
I disagree - for a mere $700, including necessary peripherals, it will retard each cylinder individually and create a separate timing map for each one.
That way, if he's got one oily or carboned-up cylinder, that one will be retarded, but all the others will remain advanced.
If I had the scratch, I'd get one. I tried one from the '80s in my 455 around '92, but I couldn't get it to work right.
The technology's like from a whole 'nother century now, man!
