wayfarer Posted January 31, 2010 Report Posted January 31, 2010 Just a heads up for anyone needing/wanting to source forged pistons for their next project. This is a fairly new company and they have been focusing on the chev-ford applications (until we got them moving toward Mopar). These 276 DeSoto Hemi pistons are from the AutoTec line and are the first from these nice folks, and they are nice! www.racetecpistons.com although it is difficult (impossible?) to see (above), each piston has ID info etched into the area under the pin boss. and there is no mistake who the manufacturer is... One last pic; Wrist pins in the box, each pin wrapped in a plastic sleeve. The level of shipping protection is the best I have seen. If anyone has a forged piston need (any make/model) I will be happy to call the manufacturer, check on your application, and offer a quote. As with custom pistons, making changes is pretty easy. These 276 pieces are set up for a slightly longer rod (6.125 vs 6.067) and a smallish 0.927 x 2.5" pin. These pistons are 10:1. Sorry in advance for not having a web site so you can 'look around'...

48mirage Posted January 31, 2010 Report Posted January 31, 2010 Have they got anything for us folks still driving our 6 cylinder flatties? Quote

Rodney Bullock Posted February 1, 2010 Report Posted February 1, 2010 (edited) Gary, this is great news. When I was building my 289 Stude motor I had to "settle" for some cast pistons not of the states (china) blanks. We don't know how great this news is. Up til now it's the measurement (bore size) that tells us what piston to use if we have to over bore an exotic motor. I know a couple of my friends that had to trash motors because they could not find pistons for them. They are a couple of months to late for me however it's good to know that a need has been filled out there for pistons. Forged is the best, American made is even better. I know of some Olds guys that will be very glad to hear this news. Egge has been the only game in town for a while, having some competion will bring the price down a little. If we can get some for a "Red Ram" motor I think a little V8 in my 1940 would be in the future. Just a little more power. I had the chance to see some dome pistons last wek at the machine shop. They were a thing of beauty. New machined parts are sometime to nice to enclose in a motor. Edited February 1, 2010 by Rodney Bullock bad grammar Quote
Flatie46 Posted February 1, 2010 Report Posted February 1, 2010 A friend of mine has an old dirtbike he hasn't been bale to find a piston for. I wonder if they would trouble themselves to make one or two. It may cost more than the bikes worth. Quote

I wonder if they would trouble themselves to make one or two. It may cost more than the bikes worth. Don't be so sure. When I was looking at a set of metric rings to use in my overbore, I contacted Venolia. I told what bore I wanted and sent them a stock piston, a wristpin and a set of rings. Four weeks later I received a set of custom forged flathead pistons and pins that were gorgeous, and at a reasonable price. Marty Quote
greg g Posted February 1, 2010 Report Posted February 1, 2010 Rodney, you know those little Red Rams were only a 241 and only produced 10/15 more HP than the 6. Nice looking little motor. I if Ihad one, I thinkk I'd have to put it in some kind of no hood old style roadster hot rod. Quote
Young Ed Posted February 1, 2010 Report Posted February 1, 2010 Only the first ones were 241. They were 270 in 55 and even bigger in 56. 312 I think. Quote
wayfarer Posted February 1, 2010 Author Report Posted February 1, 2010 Actually, the 56 was a 315 the it grew to 325. Plymouth had a poly head variation of the Dodge in 260 ci displacement for 1955. Our hope is to be able to offer pistons for all of the Mopes, 6's and 8's. Gary Quote
Rodney Bullock Posted February 1, 2010 Report Posted February 1, 2010 (edited) Young Ed has done his homework, I am looking at a 1955 Hemi. now I am not kidding myself. I know it's not a SBC however if I can get just a little power I am happy. At shows when you got a Hemi all the girls just want to faint:) I will not mess with my Coupe as it sits. I will wait for my 6cly to get tired then I will swap it out. I will get the motor and have it in a "prepared" state. Can you imagine 1940 Plymouth coupe pull up the hood and bang! it's a hemi and I will not change anything else either;) keep the white walls three speed.

Young Ed Posted February 1, 2010 Report Posted February 1, 2010 Rodney I did a lot of research during my brief ownership of this engine and the 55 dodge custom royal lancer that contained it. Sadly the 270 doesn't have the cool stamped leaping ram valve covers that the 241s have. Quote
Rodney Bullock Posted February 1, 2010 Report Posted February 1, 2010 UMMM that looks like heaven:) I got goose bumps all over:p Quote
Rodney Bullock Posted February 2, 2010 Report Posted February 2, 2010 Ed, would you consider that a super Hemi? I got some info from the other side. Some of those hemi motors had 2x 4's from the factory. the 241 bored is a 270 right? Quote
Young Ed Posted February 2, 2010 Report Posted February 2, 2010 Rodney Here's my understanding of these dodge engines. For the 241 there were no non hemis offered so they were red rams. Then in 55 they came out with the poly engines. So those became the red ram and the hemi became the super red ram. If you look above the plug holes on mine you can just see a hint of red from what was left of the super red ram decal. I think the 2x4 hemis probably came a little later when they were up to the 315 325 sizes. Quote
wayfarer Posted February 2, 2010 Author Report Posted February 2, 2010 (edited) It would be difficult to bore the 241 out to 270, it would leave very thin walls. The 241 is a very sweet engine and provides reliable power for most street driven cars. From experience I can attest to the prowess of a 'little' 241 when it has 10:1 compression and a mild cam regrind. The higher 10:1 compression in any of the Hemi engine makes them into a completely different animal. As for engine swaps, keep in mind that it may be difficult to do a swap where you are changing only the engine as finding the correct bellhousing may prove difficult. There are non Hemi 241 engines. One engine was used in the 1955 Plymouth (in 56 it became the 259/260) and trucks offered the Poly head 241 (in the service manuals it is called 'single rocker shaft'). The poly version can be converted to Hemi with the appropriate parts. . Edited February 2, 2010 by wayfarer Quote
Young Ed Posted February 2, 2010 Report Posted February 2, 2010 Rodney I wish I could have kept the engine that was in my 55 but I figured the only way to sell it was complete. The engine needed a sleeve in 1 cyl because the water jacket had corroded into the bottom of 1 cylinder. But our engine guru said it was no big deal and then he went over to a shelf of boxes and with his forearm wiped 40 years of grim off a set of .030 pistons for a dodge 270. Quote
Rodney Bullock Posted February 2, 2010 Report Posted February 2, 2010 This is the one I have been looking at maybe I coulds find a trans to match? Quote
Young Ed Posted February 2, 2010 Report Posted February 2, 2010 Dang rodney that thing looks ready to go. Its got neat aftermarket valve covers too. I'm jealous. Someday I'll have another hemi even if it just sits on a motor stand in my garage. Quote
Rodney Bullock Posted February 2, 2010 Report Posted February 2, 2010 Do you think this is a red ram? I know it's a hemi. I think the valve covers make it look kind a large. This outfit builds these and sells them complete. I would either save up or build my own. They start this motor for you at Carlise so you can hear it. Ain't swap meets great! Quote
Andydodge Posted February 3, 2010 Report Posted February 3, 2010 Rodney, that looks like a Chrysler Hemi, 331/354/392....physically much larger than the 241/270 Dodge Red Ram Hemi........personally I'd be happy with any of them.........lol, but the Red Ram would be an easier fit in the early Mopars.........still, as said, either would do........lol..........I have a 318 poly in my 1940 Dodge, the poor mans hemi..........andyd(apologies for the poor pics) Quote
Rodney Bullock Posted February 4, 2010 Report Posted February 4, 2010 I have been reading about the hemi for the past few day, can you tell me something. What is a poly motor? I have heard them emntioned with the hemi. What makes a poly motor Poly? I don't know if it was 392 or 354. I know it's a hemi;) Quote

Someday I'll have another hemi even if it just sits on a motor stand in my garage. Yeah, I would like to save enough to get one of those, it would take alot of time. Quote
Niel Hoback Posted February 4, 2010 Report Posted February 4, 2010 A "poly" engine has a polyspherical combustion chamber, while a "hemi" emgine has, guess what, a hemispherical combustion chamber. Quote
