Re: Engine upgrade

The second part of that assumption is doing all the work. There are plenty of modifications to the A engine that substantially increase efficiency and do not substantially increase heat output. The...

Re: Engine upgrade

This isn't strictly true. Heat, beyond the amount needed to get the engine up to operating temperature, is a waste byproduct of combustion inefficiency. The input energy of the fuel is converted into...

Re: Engine upgrade

Nice, well come over sometime.

Re: driving a car "of the era," the high-compression heads were definitely available at the time. Most heads available now are replicas of period heads. Some other...

Re: Engine upgrade

If there's an option to just do the head by itself, for less money, that's the most bang for the buck. Larger intake valves won't help much unless you follow up by using a different carb, enlarging...

Re: Can anyone share any information about the “birth” of this forum.

The Internet Archive is going to be your best bet for information on previous versions of FordBarn. There are snapshots capturing the old FB from 1997-2005. After that, there's a blackout until Ryan...

Re: Replacing a loose valve seat

Yep, I got the Snyder's kit with the straight valves and the one-piece guides with shoulder.

Guy did the whole repair on the driveway in front of the shop. New insert, ground all the seats,...

Re: Replacing a loose valve seat

OK, I just had the new seat inserted and ground in, plus he reground the other 7 seats. Unfortunately I had to take a call and I missed the actual doing of the thing, so I don't know what he used...

Re: Removing rust from engine

I'm in the middle of a similar project right now, and although you want to avoid removing major components I gotta say that there are a lot of reasons to consider removing them. The following items...

Re: Printable diagram for adjusting valve tappets

Would have to share the profits with Bob Johnson, it was his idea. I asked him where I could get one and he said he just made his, so then I had to make mine. I did it using an amazing website,...

No worries. As I've learned, there will be at least five comments on any post:

Re: Head gasket?

I just cleaned my block surface tonight and I mostly used a Roloc green disc and then a white disc, both on a 1/4" shank in a cordless drill. They worked well, but there were a couple spots I wasn't...

Re: Printable diagram for adjusting valve tappets

Not meant to obviate confirming with a feeler, merely reduce the risk that you overshoot or undershoot your target clearance.

Re: Head gasket?

Wait a second, doesn't the Ra number go down as the finish improves? You're saying the Ra should be below 65?

Re: Loose Pitman Arm

A drop of oil on the bolt will make sure all that torque goes toward closing the gap instead of thread friction.

Re: Head gasket?

This is certainly plausible as a theory, but I'm curious what evidence you have that improper timing -> wide temperature swings in the head -> gasket failure. Like, what forensic traces in a gasket...

Re: Loose Pitman Arm

Just as a hypothetical, suppose he measures and the problem is the sector shaft. Is he likely to want to disassemble the steering column to replace it? Even if the arm isn't the part at fault, it's...

Re: Radiator Paint

Pretty sure you can use any paint you want. An unpressurized radiator can never get above ~212° due to the laws of physics. I'd focus more on choosing something that's aesthetically what you want...
