Just in case some of you folks think a 241 is too puny to get the job done I'll offer this note from a recent customer: Hey Gary, I just wanted to let you know that my 241 pulled 427 hp @ 7,000 rpm last Monday. We woke up the neighbors in Tillamook with that thing! We made three back to back pulls and the water temp never passed 180 and the oil stayed around 80lbs. Boost was 10 lbs. We started this thing with stock manifolds and it pulled 392 hp , but the water temp would shoot up to 235. So I built my first set of headers and this thing really responded. It ran strong and idled smooth. Now to install the Hilborn two port and see what happens. Thanks for your help, your parts and advice, Tim .
It is a pretty basic build. Stock crankshaft. Aluminum rods. Venolia blower pistons. The heads are a set of 315/325 heads done for me by Shady Dell Speed Shop in PA. I wont give out the flow numbers...but obviously they work very well. This engine also uses a special set of rockers that I put together. That's all I can say. lol
Leave us not forget Markley Bros went 260 in a tank with a 260 inch Dodge in 1960 or so. Yes they will run
It's like a 241 bored .125. Or a '55 Plymouth block that Plymouth rounded down to 259. But dsince the 260 Dodge was well established as a SCTA engine running in the 260 inch class, it was called a 260 in Markley's tank. Or in my Bantam. You could round the numbers either way.
Interesting about the oil pressure. Is that a heavy weight oil? ...or maybe an external oil pump/dry sump type setup?
What did you use for the blower intake? Those low deck red Rams can be built tough - here's the one that Bruce Crower built for Indy....
259 could be a Studebaker. But it's like the 301 Chevys. A 283 bored .125. GM called them 302s. Unless you have some phobia about numerology it.s immaterial. When Bones and Charlie were running the little Dodge they were called 260s. Newer guys may call them what ever they want.
Gary, thanks for posting the thread, and ALL for the input. The baby Hemi doesn't get much ink, so it's engrossing to hear what guys can wring out of them. Hemis are all like icecream, IMO, I never had any bad icecream, and this proves there's potential in any Hemi (though I understand from the Hemi regulars' earlier comments that some of the very early ones -- especially Dodge can benefit from the addition of a vibration damper).
I AGREE I have my 241 but its just .030 with a high lift cam and bigger valves. going in a 34 ford truck, full fendered of course.
The owner has not yet released all of the specific build details for public disemanation. The original destination was a 41 Willys p/u but that rig 'escaped' so he is now looking for something else 'small', maybe an Anglia. Offers, anyone?? .
This one never pulled 427 hp anywhere. But it was sure fun for a kid just out of high school and the Army
Shhh, don't tell anyone else......I have been getting all the baby Dodge Hemi's & Polys I can get my hands on since I spoke to Dan Hostetter from San Diego years ago..... giving me the goss on how good they are. In the Tex Smith Hemi book there's a small story on the "HOT" set up in the early days at Bonneville ....Yep 259 Plymouth Poly block running Dodge Hemi heads keeping under 260 cubes & setting records no doubt.
