I have been running a set of Borla 40659 on a 63 Galaxie since 2019 with no issues. The body is 14” long with 2.5” inlet and outlet.  They aren’t real quiet but do not have any aggravating drone or real objectionable noise levels at highway speeds. They’re mounted in front of the axle with full length tail pipes on a mild 428 stroker with a TKO 600.  Less than $200 back in 2019 but closer to $300 now, they are probably some of the less expensive mufflers from Borla. In 7 years I don’t think the noise level has increased or any noticeable deterioration so I have no real complaints. 

Rock Auto shows some .010 under Mahle/Clevite bearings.  I bought some back in December, they delivered in just a couple days.

I did something very similar to Jim’s instructions on TKO600 installation.  Downside was that crossmember moved back just far enough the emergency brake cable did not reach its mounting location.  I fabricated a new mount for the emergency brake cable and mounted it to the crossmember to resolve.  Worked just fine.  I’ve got some pictures and more details somewhere on my laptop. If you need mor details message me and I’ll find them.

Sent you a private message about the 428. Check your messages. Thanks

Have a friend in Milwaukee that specializes in T10’s and Toploaders. If the distance isn’t prohibitive please advise and I will message you his phone number. 

I’ll take them.  Where are you located in MN. I’m in southern MN so will probably pick them up.

Thanks.

The distributor really shouldn’t be that hard to turn. JMHO. I have seen one, on one of my 390’s, where it was almost impossible to turn by hand. I took it apart, cleaned and lubed the shaft and bushings, it freed up nicely. Hopefully one of the builders on the forum will second my opinion.
