MFM,
Tom Langdon from Stovebolt retired, so that rabbit hole is closed off. I was into his work years ago. I also saw that Power Nation.
I would love to get a 292 and work that engine out, but those motors had tall heads so they only fit in trucks, and today finding a 292 is not so easy. There is one on EBAY now for $1800.00 that was a stationary motor, perhaps to pump water or power a generator.
It is a big project building a motor. Basically it involves a lot, especially money…
The thing with a 350 small block is this engine is so readily available, and there is a huge aftermarket. Parts are cheap.
Then Snarky Joe told me the old hot rod adage: “No replacement for displacement.”
350 is more than 292, and also 250. Hmmm… A stroked 383 crate motor: 450 HP; 444 foot pounds of torque… That amount of power is good for destroying tires. I figure my C-10 will weigh about 3600-3800 pounds.
My 84 Jeep Scrambler weighed 3000 pounds without the doors and top: 350 HP and 400 foot pounds. I think 405 HP from a ZZ6 is enough.
“No replacement for displacement,” though…
Anyways buying a Crate Motor from Chevy is actually the most cost effective. These engines and tranny packages are mass produced and there is an economy of scale. Warranted I think for 2 years or 50K miles. This is brand new and not rebuilt…
My 250 inline 6 could be a 250 HP pretty easily with natural aspiration. The trick is major head work and bigger valves with a cam. The guy who kinda did all the heavy lifting now is retired. Right now it is stock and produces 155 HP, red lines at 4200 RPM. A 250HP I-6 would be a screamer that rev’ed high.
Tom built out a 292 and it had a great flat torque curve on the dyno. That engine was mighty cool but I bet expensive. A powerful engine without a turbo.
Anyways, once I pull the head, get new valve seals, and get hardened valve seats installed, pretty much my old 250 that is 59 years old, only has 61K miles on it. My phase one is do up the chassis and use the truck with the 6 and three on the tree. No power steering, so a very different driving experience.
I am pleased that I figured out my wheels and tires.
I also found out that my old OEM 6-bolt steel rims sell on EBAY for about $125.00 each. Know I have also a fifth spare rim. I think mine would sell fast because I have a complete OEM set and it has a wonderful patina where the white paint is now a shade of ivory.
The chrome dog dish hub caps also sell for big dollars. My version seems not so available, or abundant, and I have an entire set. Today the dog dish and “poverty” caps, were on the lowest cost cars and trucks. Today they are a badge of honor and a status symbol.
On the 18 inch steel wheels I like, they can drill and add clips so I can retain my dog dish caps.
235/55R18 Bridgestone Dueler on the front that is 28.2” tall (diameter), 5.1 inch sidewall for some cush, and a 9.3 wide tread.
The rear would be a matching Bridgestone Dueler 255/50R18: 28” tall; 5.0” sidewall; and 10” wide.
This would be with a 4 1/2 front drop and a 6” rear drop. I figure the top of the top lip of the front and rear fender would have a height of 28 inches from the ground. I still would have a good amount of truck height, have a good amount of ground clearence, and would not loose any load capacity. It basically would remain a half-ton truck, but kinda with a minivan height.
Figure the guys that slam a truck and use airbags use 20 inch and 22 inch diameter rims with low profile tires with profiles that are either 30 or 35, basically almost no sidewalls.
A near OEM size on a 1966 C-10 is a 225/75R15: 28.3” tall (diameter); 6.6” sidewall; and a 8.9” width. My diameters are not far from OEM, but the profile and width are both lower and wider that are kinda modern.
A big reason I want the 18 inch wheels is I want 13 inch rotors, and this also means 6 pistons on the front caliper, and 4 pistons on the rear caliper.
Don’t forget 405 HP from a ZZ6 crate motor. Also know that my 250 cubic inch I-6 weighs 440 pounds. A regular Chevy 350 small block weighs about 550 pounds, but the ZZ6 has an aluminum intake manifold, and aluminum heads. Add on a pair of headers and at least 100 pounds is shaved, perhaps more… So the ZZ6 likely will weigh less than the I-6.
The SM318 three-on-a-tree tranny only weighs 65 pounds. The T-56 six-speed weighs 130 pounds.
I can’t justify the 15x6 steel rims because that reduces the rotor size to 11 or 12 inches. Perhaps too much sidewall and flex also at high speeds.
Great brakes are an asset.
Anyways an evil truck…
