I’m currently in the process of building a 1932 3w . I want to run the stock hood tops /25 louver hood sides without modifying them .The abandoned project came with a corvette 327 . I know it’ll fit and run great but would be cool to have something more unique motor wise . I was told one of the smaller hemi’s would be possible to run under the stock hood /hood sides . Is there a main reason to go with one or the other between the 241 or 270? From some of the previous threads I searched it sounds like a cam change , moving up compression. And a few other things can really make these motors have a nice increase in HP/TQ . look forward to any insight /input on the motors . Thanks
The 241/270 engines are the same outside width. You would need small blisters to run one without moving the firewall back. It would take several inches to get it to clear. The engines fit perfectly with a stock firewall. I bought Rootlib smooth sides and some blisters they had for a MG or something. The 270's have slightly better heads and valves. They have slightly more compression due to the increase in displacement. It is hard to get much cam in them without going to solids. The lifters have a very small working range where they will pump up. Cutting back the boss around the intake valve guide helps a lot. Only intakes are by Offy and the 3x2 is OK but the 4 bbl is sketchy. Run a 70 318 distributer. It drops in with no mods.
I would recomend a 318 balancer it needs a special key or the keyway recut. as for ignition I went this route with a chrysler module http://www.gofastforless.com/ignition/points.gif MSD box at NAPA $300 Chrysler unit $50
Look for the Hemi tech information thread on here. https://www.jalopyjournal.com/forum/threads/hemi-tech-index.118764
It's hard to see, but it looks like the bottom of that firewall has been flattened, and the engine backed up.
The 241-259-270 is a great little package and basic hot rod parts really wake them up. As noted, the biggest challenge in the intake as the only oem 4bbl is from a 270 and a bit difficult to find. The Offy would be good if they were actually making them but I heard there was some casting problems. Send a PM or call if you need help along the way.
Bare with me for just a bit, probably less expensive to make more power out of a SBC than a small Hemi. Hide the SBC. To me the “cool factor” of a small Hemi in a hotrod, is the looks and letting other see you have a Hemi in it. I say leave the hood sides off and display it
Yeah.....You ever see Dolly Parton in a moo-moo? Porn star in baggy pants? Shelby Cobra painted camo? (I don't think so!!) Show-it-off....if you can!! 6sally6
A Hemi is big on the kool factor. I've got a 270 in mine with a BBC water pump, 4spd and 318 dizzy. The 241/270 with an aluminum intake and headers weighs less than 50# more than a sbc
There is only one man on this planet I know of that would put ARDUN New York on a set of little Dodge Hemi valve covers! The Scrub!!!
I’m in the process of gathering all the necessary hardware to begin a 241 build. Waiting on the pistons and valvetrain. I scored an Offy intake and a WCFB. My carb guy has the WCFB. Eventually one the motor is fired and broke in I’d like to explore a multiple carb setup.
My 32 3-window has a 55 Dodge Super Red Ram 270 Hemi and the car has the 25 louver hood sides without any bubbles. I am using the stock valve covers. It is a close fit. The front outside corner of the valve covers almost touches the hood sides. The car has a GOW type front suspension and the 37 V8 60 tube front axle is about 5-inches forward of the stock position. The hood top and sides were special ordered for this added length. It is probably the added length that allows the hood sides without bubbles. I was running the car without hood sides when the finned aluminum valve covers were on the engine. These covers are larger than the stock ones and would not allow for hood sides without bubbles. Sorry no photos.
I had a "T" bucket that I built in the early sixties. It initially had a "junkyard" 241 2 BBL that ran OK, didn't smoke much, or make funny noises. The best thing I could say about it is that it was fun to drive. Just about the time I got it drivable with the 241, I was able to buy a wrecked '55 with a 270 4 BBL. I was familiar with the car, as it was purchased new by the family of a high school friend, and was pretty sure the fifty-some thousand miles on the clock was correct. I installed that engine in the bucket, and what a difference! That car weighed 1835 lbs and had the stock Dodge three speed and 4.30 rear end gears out of a Plymouth station wagon. With a set of Ellison recapped slicks on the rear, the car was a block to block beast. Low gear was only good for turning those hard, re-capped slicks into smoke. Although the main difference between the engines was probably overall condition, I was still so impressed by the 270 that I later passed on a couple of used 241's waiting for another 270 (which never came). A 270 with a 4 BBLhas got more than enough power for a light car.
Correction Dept. - While the wheelbase has been lengthened with the GOW type front suspension, the body remains stock. So, the hood is a standard size. Sorry about the misinformation. The engine has a reground cam for more slightly more lift and duration with hydraulic lifters and adjustable push rods. Stock compression ratio. The Edelbrock 4V carb sits on the original 4V manifold with an adaptor plate. Sanderson headers for the exhaust. The ignition is a Taylor Electronics Vertex distributor. Transmission is a T5. Rear end is a 40 Ford with a 3.54:1 ring and pinion driven by a quick change with an under drive ratio for a final of 3.9:1 that works well with the T5. Pretty much a stock engine. Runs great and plenty of power and torque. Apologies again, no photos.
I used that book to rebuild my 270. I found that the small block, big block and hemi blocks were pretty much the same. The book covers all the basics needed to rebuild all the hemis. All the hemis seem to be pretty much the same also.
The other side of this coin - Poly motors using hemi blocks- Have a 325 Dodge poly in a '32. Hp is really close to a Hemi and the intakes ect. all fit. Newc
I'm in the process of building a 241 Dodge hemi for my 53 Studebaker Bonneville car to run in E/Classic fuel Altered
