Re: Can a steel flywheel be machined?

Just for my info, years ago I ran an aluminum flywheel with a steel insert, about once a season the clutch would start to chatter, steel insert was warped, replaced with rivets, used the rivet machine for big truck brakes. Those inserts I assumed were steel, and they got hot spots and eventually war...

Re: Jon Kaase tips and tricks

Thanks for sharing, great video. The section on rod bolt stretch was very interesting, Kaase was looking at a cheat sheet about bolt stretch and clamping force, does anybody have a source or link to such info?

Re: Can a steel flywheel be machined?

I live in the country and the nearest shop that will properly grind a flywheel is an hour away, so I understand your pain. But my experience is that when you try and turn them on a lathe the hard spots are harder than the lathe bit and or so hard the tool holder flexes and the bit rides over the har...

Re: Another carb question

being Edelbrock AVS carbs yes the metering rods should interchange, the original AVS carter carbs had three steps on the metering rod, and will fit in the AFB as well.

Re: static vs dynamic compression ratios

OK I may be all wet, but over the years many times I get engines that just don't run as well as they were expected to. Many times I get theses engines and the owners have no idea what camshaft was used or what the static compression ratio is. So I do a cylinder leak down test to verify rings and val...

Re: Can this be honed out or does it need bored?

use the fingernail micrometer, if you can catch a fingernail on the scratch, ridge, rust marks, it needs to be bored.

Re: maxwedge heads

I race NSS, and have worked on several sets of original max wedge heads. and for my own race engine years ago purchased when they were available a set of the mopar performance reproduction max wedge heads. Ran these on a 496 and then a 512 wedge with a 1964 cross ram. I had a stock racer give me a s...

Re: maxwedge heads

I agree with mag2555, going to the bigger exhaust valve usually does not improve performance. either with the stock older max wedge head or the newer mopar performance reproduction head.

Re: Lubricating the backs of bearings

I do not want anything on the back side of the bearings, oil or dirt, I want the bearing locked to the caps, rod or main. Everything gets wiped with a light oil until the towel comes clean with oil only on the towel before assembly, cylinder walls and journals, I have always been anal over the years...

Re: Understanding dyno results after a final drive ratio change

The gear ratio does not materially affect chassis dyno numbers. If you were going from say a 3.08-1 to a 4.88-1 you might see a slight drop due to the higher friction of a higher ratio and the inertia effect of the faster RPM climb rate. For the learning if you have a manual, you could do pulls in ...

Re: Edelbrock/Carter Carbs On Dyno ??!!

Hmmm. I think that wouldn’t work. There is only like 2.5” from the top plate to the bottom of the plenum. I think the four hole spacer and even the open spacer is less than ideal because once the Mixture leaves leaves the bottom of the spacer it’s really asking a lot to make the mixture transition ...

Re: Edelbrock/Carter Carbs On Dyno ??!!

I run two federal mogul AFB's in a NSS car, runs 9's and I have buddies that take out the secondary air valves and they ran better, on my car nope, it just stumbled and fell on its face. I foot brake my car just off idle. If I remember right the air valves when closed keep the fuel high in the tubes...

Re: LS crankshaft bolts source for long ones

Thanks guys for spending the time to search. I was putting in just 11MM 1.5 pitch bolt into the search engine and got nothing. When you showed me the picture of the BMW bolt, I started adding stuff like head bolt to the search engine. Several engines use 11MM head bolts. Called my buddy who bores en...

LS crankshaft bolts source for long ones

Trying to dyno my first LS engine on the dyno. I have an adapter made that bolts to the crank flange, problem is LS engines have a 11MM 1.5 thread pitch, and I need 6 bolts 1.5 inches long, or 38MM long. And nobody seems to make such a thing. I talked to a machinist about having some made, but that ...

Re: If you’re familiar with portable rigid hones (ie. Sunnen AN or Lisle15000) I could use some help please.

Hi guys, My background is that of a tech, not a machinist. I’m familiar with working with cylinder surface finishes, just haven’t been the one actually doing the honing (other than minor surface conditioning). I own bore gauges, a profilometer, mics, etc. I’m working with a rigid hone made by Lisle...
