Re: Spark Plugs.. Resistor V. Non-resistor

For bikes, many use resistor NGk plug caps rather than resistor plugs.....Both are 5000 ohms, but the caps are a bit bulky and may not fit with some headers CB1100F_Spark_Cap_XD05F_01.jpg CB1100F_Spark_Cap_XD05F_02.jpg Strangely, the almost-90-degree plug caps were easily disassembleable; while the...

Re: Longevity of flat plane crank engine?

My point, regarding 180 cranks is, will a 3 main crank, possibly offset some of the vibration and harmonics that the 180° crank generates? It seems like it would make it worst but, the Novi, didn't seem to have any problems. How big were the journals, and how much overlap between mains and rods? Ho...

Re: C10 350 eddlebrock 1826S won't run right

What year truck is it on ? Chevy ? More specifically, what intake manifold? Iron, with the exhaust-gas channel under the front of the carb? Rich-smelling exhaust is generally misfire, where the whole cylinder's charge of fuel goes out the exhaust valve. Even lean-misfire will smell eye-burning rich.

The Beryllium dust is toxic.

The dust will get on your clothing, potentially contaminating your family.

Re: Looking for some Help...SBC Oil fouling plug

I think I will pull the springs on #1, feel the guides, re-seal the rocker studs, and put on two new seals. Yes, sir. As suggested, the finest thread sealer I've used is Loctite/Permatex "PST" which comes in several varieties. #592 is the easiest to source--most any auto parts store has it. Not onl...

If the mixture was "right" with the PCV system in place, adding a massive air leak--an uncorked 3/8 hose--would lean the mixture to the point of stalling the engine.

Re: egr tube repair

Is the original tube "corrugated" so that vibration won't crack it?

I'd be a bit concerned about using ordinary tubing that's not designed to flex.

Because Ford did.

Re: Looking for some Help...SBC Oil fouling plug

the PCV system is the stock looking system as used on the L79. It was referred to as a closed system The 1966 "closed" PCV system had a PCV valve that was threaded into the oil filler tube on the front of the intake manifold and a hose that ran to a vacuum port. Another hose went from the back port...

Making the competition waste time, money, effort, and enthusiasm trying to reverse-engineer the thing, when they'd be better-off dealing with their own combination rather than monkey-see-monkey-do with your stuff.

Re: IHC V8 heads

Provides a nice squish area with the piston, lots of in-cylinder turbulence. Pushes most of the fuel/air towards the exhaust valve.

Not so different from the Stovebolt Six, and the "Mays Fireball" Jaguar V-12 head, except the piston is dished instead of the head.

I'd be really surprised if Rhoads "made" lifters...ever.

I expect they buy in bulk from whoever they've chosen as a supplier; pull 'em apart, machine some magic into them, and then repackage them as their own.

You may need the shaft as-is, for evidence.

Can you find another shaft to get ground so that you have one to use?
