Gary, I agree. Hey, serious question (though it's ALSO probably been addressed elsewhere): As far as the average Joe (who, let's say could only manage the cost of a split intake and Fenton headers), what realistic horsepower could be made out of the Chrysler 265? Sure, lots of people have gotten exotic and gotten amazing hp & torque from flat sixes, but I just mean Joe Average. Thanks for giving this some brain power, buddy.
Ran across a "K" series Dodge truck. 2 1/2 ton flat bed used for farm hauling. bought new in 54 by the fellow's father. He said he learned to drive on it, but said of all the trucks on the farm, it was the dog. And as the youngest kid he had to drive it as the older brothers grabbed the other trucks. I would imaging that its doggieness is probably related to gearing rather than the engine, so for a "speed application" a slow turning engine pulling a low numeric gear and tall tires. I would imagine that you would need to keep it at around 3000 rpm to keep it alive. Compression and breathing would need improvement.
These big sixers have huge strokes so horsepower is not your goal, you will build the drivetrain around the massive torque and a redline of less than 4000, kinda like a diesel. Sorry, no hot-rod numbers to throw around. The oem torque could probably be improved but if 'too much' is attempted then the peak torque rpm gets too high and you have alot of iron flying around at some uncomfortable speed... http://dodge-semis.com/Brochures/OZ_1955Fargo/pg02.html .
Dodge and plymouth cars are 23.5 Chrysler and desoto are 25 inch, All canadian manufactured cars used 25 in regardless of displacement. The HD Dodge Truck engines are 33 (maybe 35) inches long The stroke on the big 6's is 5 inches and over. Also a repair concern was a tendency to twist the drive flange of the end of the crankshaft. A home modified 265 might get you 150/160 HP with dual intake dual exhaust and miled head and deck, the torque however might be above 250 lb ft.
Gary, your comments REALLY answered the gist of my questions. SURE don't want your foot taken off by scrapnel! BUT, can the 265 make, say, 250-265 hp relatively safely?
I haven't checked in in a while - here is my big six truck. A 47 3 ton: http://www.austinsailor.net/47_dodge/47dodge.html Mine has the 331 CI. I wouldn't mind finding one of those dual carb/dual exhaust setups.
There was a semi around here that hauled farm fuel that had a 413 six in it, 4 and 4 transmissions, single axle. Tremendous torque for the day.
--------------------------------------------- Hmmm??? Forget the 413 Mopar 6! Just get the original rocket motor up and running again, attach a couple axles, four wheels and a cockpit to the fuselage, paint the word "ACME" and a Bonneville competition number on the side, add some fuel and go out and do ol' Wile E. Coyote proud!!!! Mart ================================
The "Bottle Rocket" project got side tracked. The limit for vintage engines from SCTA is 375 ci. In the real world it would run in BGL where the record is around 300 mph. The tires to run there would cost around $3,000. To pass tech would cause me to be homeless. We'll find something to do wit it, maybe a wood chipper or a snow blower. Wile E. Coyote would still like it.
the only one i know of is a 413 6 in a dodge truck is at the gold king mine and ghost town in jerome az.. old don would love to tell ya about it...
My 413 has mining history too. It came from a Dodge truck that was converted to run a ball mill ore crusher on the Comstock Lode near Virginia City, Nevada.
who pissed in your cherrios? The thread was dead and, once again, a newbie drags an oldy out of the archives. Just how hard is it to look at the last date and understand what it means. The newb had nothing 'new' to contribute to the original post other than rack up a post count, kinda like you bro. .
Just went through this old thread and found that my picture links no longer worked. I fixed them I think.
