Ralph I have replaced several 6x9 speakers with the following method: - Trace the outsde outline on a piece of 1/4 inch plywood and cut it out marking and drilling the mounting holes. You now have an adapter plate - Find a good speaker that will fit within the boundaries and cut out the...

Can anyone explain what is involved in balancing the flathead V8. Is there any techniques that could be applied if assembling an engine at home or is specialized equipment involved. Also if one was to carefully weigh each reciprocating component and equalize their weights before assembly...

Does anyone have any information on a 1932 Lincoln 385 V8. I believe it was a 60 degree design.

Does anyone have any idea on how many V8 engines were produced from 1932 to 1953? This would include engines for the military also.

Just looking for a simple recommendation for a valve reseater. The type that has a guide with either a cutter or a grinder wheel. That's all! Don't worry about carbon or global warming.

I am doing a valve job and I need a tool to clean up the valve seats. I used to have a reseat tool many years ago but it has since disappeared and so I would like to buy a new set. Can anyone recommend a suitable tool? Thanks

If those results for the 39 engine are from the curves on the VanPelt site, I notice that the advertised HP and Torque values are below the curve showing that FORD took the conservative approach in 1939-40 and did not increase the numbers for sales reasons.

I understand there are 2 popular SAE Dynamometer standards for correction factors - one is J607 which is the older and one is J1349, the newer. The J1349 assumes a mechanical efficiency of 85% while there is no mechanical efficiency discount with the J607. This could mean about 15HP difference...

Wished I could Bro but just type in the 1949 ford dynamometer building and it will come up.

In 1949, according to LIFE magazine, FORD built a brand new Dynamometer building housing 14 "State of the Art" Dynometers. They tested the Flathead 8ba engines sometimes for 90,000 mile endurance tests. Look it up on the internet. Why did they show consitently 100 hp dyno tests? In spite of...

I saw the results in JWL's book and was confused. All the official Ford curves show substantially more torque and HP for a stock engine. The ones I looked at were from the FORD engineering dept, not the sales or marketing division. Perhaps there is a difference in the DYNO characteristics? or...

With all the experts on board I have a question regarding the speed limit for the Ford Flathead V8. In the old days we revved these engines beyond belief. They actually screamed, especially in trucks with low ratio rears. But somehow they seemed to last with no block cracks or other defects...

That picture of the Air Canada Viscount brought back some memories. My first ever airplane flight was on a Vickers Viscount. Was going on a job interview. The sound of the engines made for some nice sleeping. BTW got the job offer! This was in 1966.

Answered my own question per attached diagram.

We do a compression test and measure maybe 110 psi at cranking speed. What do you think the cylinder pressure would be when we run the engine? Will it be higher under load at WOT and lower at idle? A professional re-builder told me at a recent show that the maximum pressure is close to the...

Has anyone had any experience with the Gapless ring? It overlaps at the former gap and is said to improve HP, reduce blow-by and keep alcohol out of the crankcase in race engines. Rotation is probably not an issue in either the north or south hemisphere with this ring.

There seems to be convincing arguments as to piston ring rotation. A few questions may be in order: (Assuming a cylinder bore that is in tolerance and not worn to excess) What effect does the cross hatch pattern have on rotation? After installation and start up, if the rings rotate do they...

You are both right!

You are 100% right!

It bother me why I can't find my diagram. Never re-organize your shop. Leave it alone. It may seem messy but at least you can find things. But I am going to make the supreme effort and find it and compare it to what has been suggested. I don't think we are too far apart. I will post it when I...
