AlbertS Posted November 27, 2022 Share Posted November 27, 2022 I am hoping (patiently) for Rookie Resins to reopen, but if not, I am wondering, you know how GM made a small V-6 for some of their trucks, well does anyone know of some 1/16 scale S-10 vehicle models (or something similar) that had a V-6, then would seem about the correct size when used in a truck at 1/25 scale?

Plowboy Posted November 30, 2022 Share Posted November 30, 2022 Grab a 409 and start cutting. That or contact someone that does 3-D printing. Quote Link to comment Share on other sites More sharing options...

What year range, and truck size do you want. The S-10 kits do have sixes but those are small trucks. Quote Link to comment Share on other sites More sharing options...
1972coronet Posted November 30, 2022 Share Posted November 30, 2022 You mention Rookie Resins, @AlbertS, so I can imagine that you're referring to the GMC "big block" V6 series (305-351, et seq.) of 1968 & earlier. There aren't any kit offerings of the big Jimmy six other than the Rookie offering. I, too, was under the impression that the Chevrolet 'W' Engine (348/409) would be a good start but I was informed that the GMC big six actually dwarfs the Chevy W!

Mark Posted November 30, 2022 Share Posted November 30, 2022 The GMC V6 is a heavy slug of cast iron. A couple of Sixties car magazines ran articles on swapping them out for Cadillac V8 engines. Less weight over the front axle, and better fuel economy with the Cad. Quote Link to comment Share on other sites More sharing options...
NOBLNG Posted November 30, 2022 Share Posted November 30, 2022 (edited) It sure is a heavy beast! I dug this pic up off the net of one sitting next to a chevy small block.😬 The plaid valve covers were a factory thing apparently.

NOBLNG Posted November 30, 2022 Share Posted November 30, 2022 (edited) They were available in 305, 351, 401 and 478 cubic-inch displacements and even ganged together to make a V-12.😎 Edited November 30, 2022 by NOBLNG 1 Quote Link to comment Share on other sites More sharing options...
Mark Posted November 30, 2022 Share Posted November 30, 2022 I'm surprised that someone hasn't gotten around to doing a 3D printed V12 version, at the very least. Quote Link to comment Share on other sites More sharing options...

I am looking to build several GMC 1/25th scale farm trucks, as from my youth, that mid 60's range engine, which had the same block but were drilled out to be 301,351,401 cubes.

A couple of Sixties car magazines ran articles on swapping them out for Cadillac V8 engines. Less weight over the front axle, and better fuel economy with the Cad. All I know is we were farmers, with several straight dump trucks hauling lots of grain around. Specifically, side by side, had both a Ford and a GMC, both with 401 engines, and the GMC would out pull the Ford. My thoughts are even though the same size in terms of cubic inches, because the volume was spread out over more cylinder's, the V8 Ford did not quite pull like the V6 GMC. Thanks for your response, and don't get offended by my next sentence, but, I am sure the "car" mag only cared about 1/4 track times, not day-to-day work and results.

NOBLNG Posted December 2, 2022 Share Posted December 2, 2022 The Mount’n Goat V6 is pretty tiny. You might be better off starting with a 409. The V8 from the Crew Chief Blazer is kind of a big mis-shapen thing that could be shortened up. It likely has the transmission that you would need also.

1972coronet Posted December 2, 2022 Share Posted December 2, 2022 The MPC Jeep's V6 is the odd-fire 225 Buick (Dauntless, et al.) engine. Quote Link to comment Share on other sites More sharing options...

There is an issue with 3D printing. Everyone wants an "Accurate" version of whatever engine they seek, however finding accurate dimensions and drawing of these engines is sometimes not possible. I have drawn engines from original blueprints. This allows me to ensure that the engine is accurate and to scale. However when those do not exist, where do you even start? I have done a lot of searching and I can find a million pictures of the GMC V6, but nothing other than some dimensions that are based off of vague reference points. They will say it 28.5in long, but from what to what? If someone can find me a blueprint type drawing of a GMC V6, or any other engine you want for that matter, I would be happy to draw it up. But, without it, the best I can do is wild guesses from internet pictures. I am working on a Ford inline 6 right now that has me stumped for this very reason. Then I look for pictures of it and the pictures all vary and do not differentiate between different years, bores, etc. Without accurate drawing, the engine will look only vaguely like the engine it is supposed to be, and likely not much better than the plastic lump that came in the kit. So, the issue is not lack of interest in doing the job, but lack of technical data to do the job in a way that people would actually want to buy it. 1 Quote Link to comment Share on other sites More sharing options...
Mark Posted December 6, 2022 Share Posted December 6, 2022 Which Ford straight six? The two "classic" Sixties/Seventies engines (144-250, and 240-300) have both been done in plastic. That would leave the later fuel-injected version of the truck 300, the first overhead valve six, and the 1941-51 flathead six. Quote Link to comment Share on other sites More sharing options...
