Big R Posted May 25, 2021 Share Posted May 25, 2021 Got this motor in 57 b42. I can’t find a picture of a mack motor that looks like it and I can’t find any info on it. Hoping someone knows what it is and if it could have been original. 1 Quote Link to comment Share on other sites More sharing options...
Vladislav Posted May 25, 2021 Share Posted May 25, 2021 It's definitely not a Mack motor. Vlad Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment Share on other sites More sharing options...
Mark T Posted May 25, 2021 Share Posted May 25, 2021 Almost looks like an old REO Gold Comet missing a couple things Quote Link to comment Share on other sites More sharing options...

Rob Posted May 26, 2021 Share Posted May 26, 2021 Both the REO Gold Comet, and IH Red Diamond series were popular engine swaps when these trucks routinely operated. Considerably more power than the EN-401/402 Mack flathead gasoline engines. Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

mrsmackpaul Posted May 26, 2021 Share Posted May 26, 2021 The manifolds are on the wrong side for the Reo, IH motors dont appear to have a water manifold at all Ford are wrong as are Chev, I reckon it looked a bit like a John Deere Header (combine for you Yanky lot) motor lying in the grass at the farm Will have a look tomorrow night if I remember Hmmmmmmm Paul Quote Link to comment Share on other sites More sharing options...
tjc transport Posted May 26, 2021 Share Posted May 26, 2021 first thing i thought of when i saw that pic was a continental overhead valve 6. 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

Mark T Posted May 26, 2021 Share Posted May 26, 2021 I'm pretty sure it's a REO with it's water manifold and spark plugs missing Quote Link to comment Share on other sites More sharing options...
oldspwr Posted May 28, 2021 Share Posted May 28, 2021 For reference, here are 2 other pics of Reo Gold Commets along with an advertisement for an overhead valve Continental... 2 Quote Link to comment Share on other sites More sharing options...
Rob Posted May 28, 2021 Share Posted May 28, 2021 The REO engine only had two nuts retaining the rocker arm cover where the Continental OHV engines used four IIRC. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Big R Posted May 30, 2021 Author Share Posted May 30, 2021 I love this site, thanks very much for the input. Would this Be a fairly rare engine these days? The motor is seized and we were considering a 6 by Cummins swap. Maybe we should be putting our efforts into this motor. Would like to hear thoughts from u guys Quote Link to comment Share on other sites More sharing options...
