Have you tried asking on the Boss 302 forum?  https://www.boss302.com/smf/

That's mine, been listed here for a while...https://www.saac.com/forum/index.php?topic=32865

Jim's done a couple for me, the best!

Hi Cory,

I ran Redline MT90, 75W-90, GL-4, for years but would occasionally pop out of 2nd gear under hard deceleration, just figured it was because the original gear was worn and that's the way it was. Then tried Redline 75W90 NS, which is GL-5 but advertised as synchro safe and recommended for "Muscle Car applications like Ford Top Loader, Muncie transmissions, Borg-Warner T-10 and Super T-10", but had the same problem. Then tried PennGrade 80W-90,GL-4 conventional and so far it hasn't popped out of 2nd, very smooth shifts.

Took this on Memorial Day a few years ago...

Good point, I did use an NOS Motorcraft DH-6 cap with aluminum contacts for the comparison. The Filko cap actually has copper contacts except center post which is brass. I do have a few Filko FO-100 standard black caps (copper contacts) which weighed in at ~7oz.

Thanks John. This is also heavier, ~9oz, compared to a regular cap which is ~6oz.

Period NORS Filko FO-100HD tan cap, same as Ford B7AZ-12106-A, Autolite/Motorcraft DH-146, very rare performance part that's been obsolete for many years. Don't know much about these except that they were originally used with transistorized ignition. IIRC Randy Gillis(RIP) was a fan of using them. $100 OBO which includes USA shipping.

Please PM or email if interested.

Thanks,
Dave

Does the same hold true for the BF42 plugs??  Did they become 44??

The BF42 became the new Autolite #35. After a while the Autolite 34 and 35 were both phased out and replaced by the Autolite #45. Never used the 45's myself but have heard they work well in a 289 HiPo, same heat range 5 as BF42 and 35, the 45's are still available.

I think the Autolite 44 might have been a successor to the 34 (same colder heat range) but it seems to be obsolete now.

Another option if you want to use BF32's is the Autolite #34 plug. After Ford and Autolite separated in 1972, all Autolite plugs got the Motorcraft name, Autolite continued making plugs with a new numbering system. The BF32 was now Motorcraft while the Autolite version was #34, same exact plug. You can find Autolite 34's cheaper than BF32's, here's a set on ebay now:

I have a bunch of autolite BF 22 spark plugs. Does anyone use those anymore? Any particular engine use them?

BF22's were heat range #3 IIRC, one range colder than BF32. Pretty much a racing only plug, don't believe it came factory in any production car.

Same, no issues.

SOLD - Thank you!

CARbureTER casting, recently rebuilt/restored by Fred Ballard. This is an early service part with an Aug 3, 1966 date code (3H6B), so not numbers matching but otherwise has the similar factory OE look for a 65 or 66 carryover. Asking $1850 OBO, shipping and insurance included.

Please PM or email if interested.

Thanks,
Dave
