Re: ARP head studs

Yes, this poses quite the predicament, if you apply torque high enough to start the deformation, you will more than likely cause a catastrophic failure. Then what do you do? I do the testing on the...

Re: Rebuilt Model A Engine: What do I have?

Sure, it makes sense if you are a re-man business, bore to a single size on them all. Not so much when the supply of blocks is limited, and saving a motor is the priority. I have worked on race...

Re: ARP head studs

Brent has asked the right question, for a stock motor no gain, in my opinion.

As for the others who have the tendency to increase power output it is optional.

If you look at the grade 8...

Re: Rebuilt Model A Engine: What do I have?

Kevin,

You make a point about the header, I don't know but the flywheel is full size.
I doubt it was "raced" in any event, disassembly is necessary.

I will note though, I have had a few motors...

Re: ARP head studs

I doubt that ARP will release a stud set for the Model "A", seriously there are bigger fish to fry. Also it should be noted that there are too many different heads available for the Mod"A", and will...

Re: 32 model b engine

Or just use 12 point nuts on the rods

I have seen too many hammer jobs
Appropriate for shade tree mechanics

Re: 32 model b engine

The "B" pan should be used, it should have clearance bosses for the rod nuts. The counterweights are of not consequence, a '32 probably does not have counterbalanced crank. The rear section of the...

Re: Piston and cylinder clearance / measurement???

The Model A engine still has the physics of material thermal expansion.
The original pistons have a "split skirt" this means that the piston has a cut that allows the skirt to compress or expand....

Re: "Diamond engine"

That is a good question, I do not think so. Yep, pan drop is the only way to know.
I think time to ask Mr. B

Re: leaking head gasket?

Not that this is the problem, it is just an observation. Head stud torque drops for a couple reasons, gasket compression, stud/nut stretch or the threads in the block.

I suggest when making a...

Re: Latest aluminum block.

Inquiring minds want to know the Block status, has the eagle landed?

Not that the Winfield information isn't interesting.........

Re: French Model A aluminum head

Interesting discussion about multi plug engines, some dyno testing has shown the Yapp Lion head likes just a bit of stagger between the firing of the plugs.

Brass era cars had multiple plugs, this...

Re: Diamond B question.

There are lots of issues with the crank flanges, mainly due to the slinger and resultant reduction of material where it needs to be.
Once you have seen a flange broken off the crank, and the lack of...

Re: Bone Stock or Modified?

Chris may have hit on something here, back when the Model "A" was new, aftermarket parts were available. It wasn't un-common for a dealership to install an OHV head on one.

Re: Engine upgrade

Or, just the fact that the cooling system is in-correctly designed.
Water pump scavenging the engine induces cavitation, thermostat missing to control temp and water flow.

Re: Lightened Flywheel

Short answer is no, it has to do with the Moment of Inertia.

I short, the radius away from the center of rotation has more effect than just the overall weight.

It is a good question though, John

Re: Lightened Flywheel

The vibration, or sense of vibration can also be attributed to another factor.
The original flywheel was intended to assist in the inertia of the rotating assembly and provide low speed/rpm torque....
