Re: Supercharger Spark Plugs

Re: Specific questions re using a boring bar (Old school)

Hi Mart, with any deck-mounted bar I would recommend boring the smallest amount of material as possible in one pass. On a +.030" o'bore I would take about .024"/.025" (nominally). For a +.060" o'bore...

Re: Lifter & Spring Questions

Sort of depends on how you're looking at the valve, the groove closest to the valve "tip" is for the locks. The next one down is the seal groove! Photo below!

Thanks, Gary in N.Y.

Hi Tim, every single "negative" issue we found on the Navarro heads couldn't be argued about out at H & H. Mike (Herman) seems to be directly involved in these "new" castings??

Re: oil pump

Hi Tim, it's almost impossible today to know where parts are mfd, this is the reason we stay the course with the mfrs we've been dealing with for a long time now. I am still OK with Offenhauser.

Hi Dave, if you get to the point of opening that unit all the way up again I would talk with the shop owner and ask him to set up for the 95% filter system, really the best way to go.

Re: Video putting a sleeve in a flathead

I would've recommended putting some "green" #675 Loctite on that sleeve before installing it, if there happened to any very slight pin holes the Loctite would become the sealer!

Re: For those with machining experience. Sleeve fitting??

Re: For those with machining experience. Sleeve fitting??

Hi Mart, first item I would check assuming a deck-mounted bar here, I would recommend somehow mounting a dial indicator on the column down near where the cutter mounts.

Re: Spark Plug Protrusion into Head?

Anthony, if you can't or won't solve your plug issue with the washers then you'll need "spacers/bushings", these are machined as a 1-piece item. We've done this with a number of customers including a...

Re: Spark Plug Protrusion into Head?

That plug is the number I used in my drag car (G.M. aluminum heads), it is a reasonably "cold" plug, worked well with the 13:1 C.R.

Re: Spark Plug Protrusion into Head?

Just a heads-up, but to the best of my knowledge and as far back as I can recall all the "N" series Champions were 750" reach.

Believe I ran that series in my 13:1 468" years ago!

Thanks, Gary...

Re: Spark Plug Protrusion into Head?

While I agree about not spending a bunch of money on any heads to make things right you really need to keep things in perspective?

Just for arguments sake, if you were to spend as much as $400.00...
