Studebaker in World War Two Some of the Army 2 1/2 ton trucks I drove when I was in Vietnam were built by Studebaker.Some of the trucks were Mack trucks, Dodge, GM, International, Kenworth,,, they all looked the same, built to Military Specs. www.vietnamguntrucks.com http://vietnamguntruck.tripod.com cuhulin |

I know because there was one in my 1960 Lark. --Geary Rambler made a flathead six until about 1963 or 1964. We bought a house in 1963 and the neighbor was showing us his shiny new Rambler with a very obvious flathead six. It ran good and he was perfectly happy with it. One of the reasons flatheads got a bad rap was they would not wind One of the reasons flatheads had a bad rap was they had one hell of a bad combustion chamber shape. Way too much surface area hence too much heat loss. Smooth they were, efficient they weren't. If you want combustion efficiency, then a hemispherical (hemi) chamber is the way to go with at least 4 valves per cylinder and the spark plug as central as it can get. Minimise flame propagation distance so avoiding detonation at higher compression ratios. Throw a good bit of swirl into the combustion chamber to get that fuel well and truly mixed with air and properly vapourised. Then you have yourself a powerhouse. like an overhead. They all had over 4" strokes, so duh..., no 7K RPM. It turns out that high RPM is good for power but sucks for mileage. High RPM is good for BHP at the expense of torque. The poor fuel mileage is purely due to inefficiencies. Ramblers in the 60's were actually good cars, but economy was not the priority in the 60's. Now we have over-winding 4 bangers trying to make up the power gap. So explain to me how these "overwinding 4 bangers" crap all over the "old" detroit iron in the performance stakes! Bill Baka Piston speed is THE defining factor in all of the above. Higher RPM equals more power strokes in a given time frame. Long stroke engines have a piston speed that is far too high when wound up around 7k RPM. Remember, that piston is reciprocating, not just going in the one direction. Usually this results in catastrophic engine failure when piston speed exceeds sensible limits. Cut down the stroke and you keep the piston speed reasonable at the expense of torque. Appropriate gearing and more gear ratios compensates for the lack of torque. My current daily drive is a five speed and its fifth gear is NOT an overdrive. It's high revving 1800 cc 4 banger that pumps out 100KW and it's as stock as the day it came out of the factory. The sports models get 50% better power and still remain street drivable. Sure isn't like my younger days when we were into street rods that were barely street drivable. Sounded good though! ;-) Left all that behind in the 70's and got into shortwave for the first time. This was mainly because I was in and out of the country so much in that era that I didn't have time for cars any more. Krypsis |

Krypsis I got a deal on 5 1957 Plymouths in 1968 and had everything from a baby hemi (332) to a flathead six. The Hemi (circa 1952) was gutless and the flathead 6 was a monster chunk of iron. It did run quiet as with all flatheads the valve noise was very minimal. Bill Baka The flatheads had minimal reciprocating mass as valve gear, big advantage but they couldn't take advantage of it as they couldn't rev much anyway. Overhead valve with overhead cam is the way to go, even twin cam. Keep that reciprocating mass to a minimum for better get up and go. Krypsis |

Those old long stroke engines of many years ago, on level roads, you
could start out from a dead stop in high gear, smooth and easy as pie.They had that real good low end torque.Some of those cars had a built in air compresser at the transmission, flip a little lever and you can air up those tires. Some new car manufacturers nowadays add some Bar's Leaks to every new car and truck before they send them out the factory doors. www.devilfinder.com Which auto manufacturers add Bar's Leaks to every new car? cuhulin |

Back in the middle 1950s, Ford had better manufacturing than GM, (GM =
Government Motors) GM had better management.They got together and worked things out. Ford still does have better manufacturing than GM. (GM = Government Motors) Motor Trend picked Ford Fusion as car of the year for 2010. www.motortrend.com I snail mail subscribe to Motor Trend magazines. cuhulin |
