Re: Ford DS II ignition upgrades?

If you need to make rising HP numbers above 5500 rpm then you have no choice but to ditch that factory system, especially if your running compression ratio's above 11 to 1. LOL at you kids that apparently never had the pleasure of using points ignition with engines turning considerably more than 55...

Re: Pete Jackson BB Chevy noise gear drive parts missing

I know the Mr. Gasket bushings work.

About the thrust bearing...I would take the gear and such down to the local bearing house and let them find something that will work.

That's all I got.

Re: Engine Masters rod ratio test results

You guys are "bringing a tear to me one good eye." :D I have the same rigging and been doing the same spark gap and oscilloscope games since the early '70s. What a long strange trip it's been. First played with a couple of my father's friends' distributor machines in the 50s in grade school, used t...

Ground up cam lobe and lifter face is MUCH MORE CORROSIVE.
We haven't lost a flat tappet cam in over a year. That's about 300 cams.
No moly needed.


IIRC disulfide is not oil soluble. But you can get oil soluble moly. It's just very expensive.

Re: Whats Your Definition Of a Engine Builder ??

My Dad was considered one of the greatest race engine builders of his generation, but he was a crap machinist. He hired some of the best machinists in the country, and had the ability to measure the machinist's work, to know if it was correct, just don't ask him to machine something on the mill or ...

Re: Engine Masters rod ratio test results

Didn't see the tests...what are the bsfc's for each and is there an average given or just peaks? They tested for that, but didn’t disclose the information. So either it was insignificantly different or they felt that presenting that info would be going too far into the weeds for the general audienc...

Re: Engine Masters rod ratio test results

It's much easier to visualize the rod ratio and velocity differences if you graph it as piston position and using rod length extremes helps even more as a visualization tool. Now when you have a cam lobe profile ground using the rod ratio it makes sense and as Mike stated earlier the rod ratio test...

for the ones that watched it what was your take on it? Were you surprised the shorter rods made more power?


Is there a YouTube link to that or something? I'd love to watch that.
