What do you call the checks your government sent countries, for their citizens, who are your enemies?

I follow Dr Mercola and his web sight for true and unbiased covid reporting. jmo I am 78 years old and I said I am considering taking the vaccine. My wife and 3 adult sons will have to make their own decis...

Re: Simple idea for AR chamber off header collector

In the op’s drawing of his tapered AR, it’s not as effective as a small bullet style AR...but it’s in the right direction to add power. On the dyno anyway Do not taper your exit pipe , make it a blunt cut at 3/4 of the way into the bullet outer diameter. take a look at the majorty of winning engine ...

Re: Big Issues with Cylinder Pressure (DCR)

The crank rod piston is included in the net difference. Rotating assembly Stretch caused by rpm is not. Its the same on both motors. Aluminum block head engines are typically built with 1 whole CR increase to make same power as a identical cast iron engine does. The difference in net all in block g...

Re: Big Issues with Cylinder Pressure (DCR)

When the block heats up it grows taller. The compression the ratio drops because the block grows taller more than the rotating assembly does (aluminum vs iron) Same as the net valve lash grows larger as a aluminum block heats up on a pushrod engine.. .008" to .012" is typical on a aluminum block V8...

Re: P/V clearance measurement techniques

If you have no piston to work with it’s a different story Every time the piston manufacturer asks for free drop at over lap, they make the reliefs way to deep for me, even though I know exactly what it is with running springs and deflection loss. It’s still too deep So I’ve resorted to giving them t...

Re: duration @ .050"/ .200"

Not sure lift has to be more if the .200” is greater

Plenty of cheater cams have bigger .200” numbers with less lift than those with smaller .200” specs and more lift

Re: Top piston ring gap - whats really required?

In a perfect world where cooling systems keep every cylinder an identical temp or never ever spike in temp from a problem , you can probably take a chance on closing the gaps up... if you have the slightest issue, you could be in big trouble It may even be possible to measure the increase in power a...

I would prefer taking a chance with the post office over that drop box. I like the way in person voting works here. My identity is confirmed. I fill out the ballot.

Cloyes has a factory roller cam specificd double true roller 9 key way setup. It fits all timing covers with lots of clearance including the plastic covers.

Re: SBC LT1 / vortec compatability

Any timing gear made for the stepped-nose cams, either 87-93 Gen1 or LT1/LT4, should have clearance for the cam retainer plate and bolts, as the stepped-nose cams were never used without the retainer plate. Changing to a different style bolt with a fatter head can cause clearance issues. Some after...
