I was wondering if I could just weld the weights together in the distribotor and run 34 degree's inital timing. Of course the distibutor is an hei. It has a new module, coil, wieghts and springs. No matter what I do it messes up. Either the timing comes in to late or it comes in and then sticks open. I have also streched two springs and the they fall off. So I would rather just weld it up and set the timing at 34 degree's. So will this hurt anything. Thanks

yep you can. many racers do that very thing.

the only downside is that you must run an ignition kill switch in order to start your car. Otherwise you will kill starters on a weekly basis.

how do you do that, and why does it hurt the starter.

The ODB

how?
one usually wires a toggle on the 12v source wire going to the distributor module (depends on what distributor you're running), or to your MSD amplifier box.
you kill the ignition, then turn the key to get the engine spinning up good, then turn the spark on and it starts.

why?
starting combustion 34 degrees before TDC creates a huge amount of cylinder pressure for an electric starter to overcome.

I saw a SBC kick back one time due to too much advance, it blew the starter right off the block.....it was swinging from the battery cable

It was one of the coolest things I've ever seen.

usually the starter gear just breaks, or the nose cracks on the starter.. sometimes damaging the flexplate.
Considering steel bolts are much stronger than the common aluminum starter nose, then I'd think they should have bolted the starter onto the block before trying to start it.
That would be pretty cool though.

So then can I just run a toggle to the battery connector on the distributor cap. I know that's not what it is called, but u know what I'm talking about. Then turn it over for a couple seconds and then flip the toggle. It would also be a pretty good theft detterant system. Thanks for your help.

What we found later was they had one starter bolt and one regular 3/8 bolt.

Upon inspection, it had broken the regular bolt and cracked the block in the other hole.

I guess the timing wasn't the only reason it blew off, but it didn't help things.

Another reason I use the brackets on the front of the starter.

If your using a MSD box, you can also get their startup Retard box. it Retards your timing a certain amount Till you get the car started.

I dunno about this on the street tho.

The MSD startup retard has some problem (not sure what) and does not work very good.. I have two of these that I no longer use.

I haven't run HEI in a long time (not an HEI fan)
but I'm pretty sure it's not the Battery wire that you want to splice the toggle into. There should be an ignition wire (12v when key is turned forward to run position) that goes to the distributor to power the module... that would be the one.
If someone with an HEI doesn't answer you here, then you may have to experiment a little to get the right wire. For some reason I think the big battery wire just feeds the coil, and that there is a smaller ignition wire that goes into the distributor housing to turn on the module.
anyone.. am I right?

mustangs killer

Yes,your right. Thats the one I'm talking about. Thanks again.

This is a race car right? Under load at low rpm, it will ping like crazy with that much advance. You will need to idle it up quite a bit as well. Take it to somebody that knows HEI and they will have it working perfect.

It's not so much the pressure on start-up as it is the spark plug is firing way before the piston is to the top--pushing the engine backwards(I guess you could call that pressure). Even if the starter could force the engine to turn over, it would have to spin way faster than any starter could to actually start the engine.

MSD does have the box thatyou can mount and either adjust the timing 15 degrees either way. i have a friend that has one on his '68 Camaro BB, and he turnes it down the 15 degrees to start, then up for around town and racing. They also have one that you can tailor your own advance curve right off the box.PN 8981.
