Correct LS6 Distributor Cap?
 

Can someone please tell me what distributor cap came on the LS6 from the factory. Was it the brown R cap D309R part # 800061 OR the black R cap D308R ???
Thanks very much. [img]/ubbthreads/images/icons/confused.gif[/img]

Welcome aboard,
It is the black D308R car with Delco Remy Patent Pending R on the top. Tell us more about you and please fill in your profile so we know who you are and where you are from.

Brown should be corvette.Shoud'nt a LS6 cap have a patent # on it, as late'67 caps had the pat/ # on the remy cap?
Tough subject as '68 was the "pat pen to pat# year for most chevys and a D308 [no R] are a nice find these days NOS.

I don't have my info with me but the patent pending # was not on the '70 cap and I believe it was not after '68 but don't quote me.

When our car was Diamond Certified last June, I had a 'runner' cap with Patent Pending and the pending number installed on the distributor. During judging, I was asked by the judge if I knew what cap this car should use. I said that it should have the Patent Pending Delco Remy R cap on it to which he replied, "then why you have the patent # cap on?" That little oversight cost my customer 10 points and me a bunch of embarrasment! [img]/ubbthreads/images/icons/shocked.gif[/img]

There will always be controversy on this cap/engine application.It should be Black,but some very knowledgeable people argue it is the Patent#,vs.the Patent Pending R.
Don't forget the distributor RFI shield....

Re: Correct LS6 Distributor Cap?
 

My 1111437 dist has a 2 piece shield that covers the points, is this what you call RFI shield. Is it rare? My 1111499 dist on my camaro doesn't have one. Should it?

Re: Correct LS6 Distributor Cap?
 

That distributor came with that shield and it is very rare to see one still on a distributor. If it went through one points change, it was generally tossed. You are lucky to have yours. I do not believe the 499 distributor ever came with it but I may be incorrect.

I have a few of the Delco Remy dist caps and notice some have different size font of the printed words and one has copper contacts vs alu. Also I have read that some do not have the "R" on them.

Re: Correct LS6 Distributor Cap?
 

From my understanding, the difference between the copper and aluminum contacts are steel body cars vs Corvettes. Also there is a letter difference in the 'D' 308 number. My info is somewhere at home.
