"JWL" is John W. Lawson, a most-knowledgeable and experienced flathead guy, whom unfortunately, we just lost this past year. You can get the book at Amazon, or at Mac VanPelt's site. This is THE flathead book!

Flathead Facts is no longer available on Amazon.

Ok so far here’s the plan/build
C1ba(8ba) block, 4”crank, 3 5/16 pistons .030 over, EAB-A camshaft(not sure what the “A” stands for), ford 8ba aluminum heads, (I have one eab head lying around but could never find the other side), adjustable lifters, stock ford intake(for now), stock distributer(for now), looks like I can rob an aluminum cam gear from one of my other engines
Anything I’m forgetting? Il be checking the piston to head clearance tonight

This gives 280 Pus ci. I have the same engine in my truck, along with the EAB cam as well, Intake is a merc with 2GC carb and a chevy distributor. Rear axle is a spicer 44 with 3.73 gears and posi. Trans is a T170 with 3 spd OD In a 47 Int KB1 Took the truck to the Weston, Andover hill in VT and drove the truck up in OD to the top of this 14% Maintaining 50 MPH. Unfortunately, The speed droped to 43 MPH over the top engine was turning 1300 RPM The torque of this engine is un believable. Truck is fore sale

And for a driver torque is more desirable than hp?

Oh YEAH! Torque is the force that makes your face look pleasingly-funny as you get on it. In other words, torque is what causes your butt to be plastered into the seat as you accelerate through the gears.

It is known that Torque and Horsepower are always equal at 5252 RPM. Given that even a reasonably modified flathead will never approach the RPM, what do you think?

Real Racers need not respond; That's a completely different set of circumstances.

pulled a piston out and found the rod bearings to be the floating style(one bearing for two rods) is this good or bad? connecting rod journals have two oil holes, short skirt(for a flathead) 3 ring pistons

Horsepower was an early sales gimmick so that prospective buyers of steam power could relate the the steam engine’s power to the familiar horse.

Torque without engine speed is useless. I can apply whatever you want with my arm and a long enough bar. Physics tells us that power moves and accelerates things including our Fords.

Whaaat?! Never heard that before. Please explain.

As "miniceptor86" said in an earlier post : "Horsepower was an early sales gimmick so that prospective buyers of steam power could relate the the steam engine’s power to the familiar horse." Horsepower is an extrapolation from the torque reading, calculated by a formula. Since it is a merely a calculation, there is always one value where it will be equal.

Jay.... You MAY need to watch this vid a couple of times for it to sink-in, but this kid explains it fairly well. DON'T let yourself get hung-up on "5,252 RPMs". Click the link BELOW!

In my 41 Pickup with a 4 speed tranny I have a late block 276 CID with an L100 cam, 3-97's, Offie heads and crab ignition. It runs great with good pull thru the gears. Drive it around town often. I wouldn't change a thing.

Tubman & Coopman
Thanks for the explanations. I learned something. I get the 5252 RPMs isn't meaningful, is just a number-crunching value in the formula. What is meaningful is: "Horsepower is an extrapolation from the torque reading, calculated by a formula." I did not know that.

When building an engine, consider the application. This usually cost less, and gives better gas mileage.
