What’s the appeal for that weights and plate combo?

Re: GM HEI #41 weights and #375 center plate wanted
The appeal is a high performance advance curve. There is a certain hei you can buy new that has these already installed. I would have to look up the part number not all are the same and a lot of new hei's are pure junk. I have it in mine and ive been tickled pink, no laziness and it gets up and goes with the old heads.
Also to the other poster , I believe i have a set . I will have to go look in the garage. Maybe two sets Ill see. |

Re: GM HEI #41 weights and #375 center plate wanted
Thanks BigTruckDriver that would be great if you do and if you can find the part number to yours also would be great. I was told by Dave to try and find these to rebuild mine, and have heard from others also so I am going to give it a try.
Thanks Kirk |

Re: GM HEI #41 weights and #375 center plate wanted
Your doing this on a 350 dist. Right? It 's been a long time now. If I remember right the #41 are in some of the 305 Dist. or the v6 dist. I have to look at my Dist. holding shelf. As said I think the center comes in some aftermarket set up Dist. for some reason Accel come to mind. You can do some searches on the they Mr. Gasket , Accel, Moroso, MSD, there is most likely 4 or 5 more can think of them.

Re: GM HEI #41 weights and #375 center plate wanted
Have you found some sort of a table or book explaining what effect these different numbered parts have on the advance curve? I would be very interested in learning more. Sorry I cant help with those particular parts you are looking for.

Re: GM HEI #41 weights and #375 center plate wanted
I don't have a table or book, my buddy told me to look for that set because it is the best combination for SBC 350 engine, so here I am looking for them.

Re: GM HEI #41 weights and #375 center plate wanted
Buy a $15 advance kit at AutoZone. Use whatever combo meets your needs. It's stamped steel cookie cutter pieces and springs. I don't think being Chinese in origin matters in this case.
As for being the "best set for a 350" there are a million combinations of 350. The only way you'll know for sure is to put the engine on a Dyno and curve the timing with a distributor machine. Otherwise it's seat of the pants feel and subjective at that. |

Re: GM HEI #41 weights and #375 center plate wanted
I was told to stay away from all the kits out there, the only thing that has it in it is the Chevrolet performance HEI Distributor # 93440806, So instead of spending $220 bucks I just want the #41 weights and #375 center plate. I guess that's asking too much. meanwhile I will continue to search junk yards around here for them, until someone tells me they have some I can get from them.
Thanks Kirk |

Re: GM HEI #41 weights and #375 center plate wanted
Looking for only the #375 center plate now, I found a set of #41 weights at a out of town junkyard.
