I think your better off having the sowing machine noise than have it clack. A really poor bleed rate on a lifter set at the top of the travel is more likely to eventually collapse. I wouldn’t be...

If you went ahead and replaced those 2 lifters on number 8 and adjusted the valve terrain more like normal I think you would be a lot happier.

Our trouble was always having dead cylinders from bad new plugs using Autolite (or Motorcraft). We always used them on Fords. My experience with Autolite is old and out dated though. Apparently...

There isn’t any hurry.

Not all the Champions are 2 piece. I wouldn’t be concerned about the two piece construction as much as the current quality of the manufacturing. I have used hundreds of...

On NGK the last digit on the racing series is the heat range.

On the normal plugs it is the first number after the letters.

Must have made sense to someone. LOL

SR cams are quite a bit different on this topic compared the HR’s. It is much easier to make up for a rocker ratio with a different profile on the SR.

They have been around for quite a while. I have not had SGI or Star Galaxy stuff for a long time. Not sure how quality is these days, but I wouldn’t be afraid of one on a budget build, it is much...

Are you shooting for 560 to 580 HP at your altitude? That would figure out to be an equivalent of around 640 to 660 HP for me a state east of you. I think that is going to need the big .4”ish ...

Nice work!

Which Jet carb do you have? Is it the stage 2?

For now I would just pull more timing out. Forget about adding octane booster on a daily driver. Drop the timing back too 28* total. It won’t give up that much power pulling some more timing...

I recall Joe Sherman had a 366 Ram Air 5 on the Dyno for Tom S that he took up to almost 7000 with a HR set up and dual springs. That probably had 2.19s. It was just a comp HR cam with magnum...

Changing to a beehive from a dual spring the minimum spring pressure drop most do is 10%, the max is about 25%. The lifter weight has nothing to do with that part of it, it all comes from less mass...

I don’t think there was a reproduction of the 067 in 1992. If you looked up a replacement cam in a book at that time I think it sub’d over too the 066 as a replacement. If it has an 068, which is...

The 66 GTO’s 4bbl std engine would have been a 067. The tri power cam was the 068 and a few later tri power’s had the 744. It is pretty common for the 4bbl engines to receive a 066 after a...

More time on those plugs would tell. If one plug looked like that maybe it has a cylinder pumping oil. But I would expect the carbon deposits to be much thicker if that was from burning oil. It...
