Re: 8ba 275 carb options
"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! Coop |

Re: 8ba 275 carb options
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 |

Re: 8ba 275 carb options
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

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. Coop . |

Re: 8ba 275 carb options
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. |

Re: 8ba 275 carb options
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

Re: 8ba 275 carb options
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.

Re: 8ba 275 carb options
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.

Re: 8ba 275 carb options
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.

Re: 8ba 275 carb options
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! Coop https://youtu.be/lt7iUBE3_AE . |

Re: 8ba 275 carb options
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.

Re: 8ba 275 carb options
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. |

Re: 8ba 275 carb options
When building an engine, consider the application. This usually cost less, and gives better gas mileage.

Re: 8ba 275 carb options
I use this unit from Speedway Motors or Amazon. On the chance that it might be restrictive, I ordered another element and made a longer center stud and run two elements stacked one on top of the other. It looks good, works good, and still fits under the hood of my '51 with good clearance. (Sorry about using a link rather than a picture; for some reason I can't attach a 250K .jpg this morning after doing it successfully for years.)
