Lifter bore back spot facing tool needed

Hello everyone !
I need to buy or rent a tool to back spot face the lifter bores in my block so I can run mushroom style lifters.
Anyone have one or know of one ?

Thank you in advance !!!

No, but I have yet to hear from anyone who had to do it (despite the old Direct Connection bible saying so). Put the lifters in, then the cam, and see if the cam can be turned!

One person posted that it's a good idea in case you float a lifter sufficiently to hit the underside of the block. Mine are miles away (well, at least 1/4") at max lift so I didn't bother. But I do run a rev limiter

Which cam do you run ? I plan on using the old Mini Express.

Thank you for your reply

Who are you talking to.. I dont see any reply..
I ran a old mushroom tappet years ago.. the old
.750 lift.. but I had a shop do it back then.. as
I didnt have the tools to do it

I used to have one of those tools but I haven't used it in 20 years so I'm not sure which tool box it is in.

If I recall I bought that tool from a regular machine tool vendor. It is a fairly standard tool called a back spot facer or something like that. I think MSC has them in the catalog for $30 or something like that.

That's the one (316 adv/0.654", .024/.028 lash) P3690588 Mini-Express. I got a used one so I sent it to Schneider to have the lobe taper restored. They measured it at 278 @.050. After regrinding it was 272 @.050, .652 lift, .018/.018 lash so actually a bit more lift than stock and slightly less duration.

If I ever get my Dart out of paint jail, I'll let you know how it runs!

DBCooper...do you have any old weathered US currency you would like to exchange for new?

I was talking to DrCharles lol

Actually I collect old paper, paper monies and coins. Love gold and silver bullion

I will continue my search with machine shop tooling sales. If you could find yours, I would be glad to buy it from you.
Thanks

Check to see if you really need it. I didn't 35 years ago when I ran the mini express.
