cdday63 Posted October 8, 2014 Share Posted October 8, 2014 For hauling shorter flatbeds loaded with hay, could an engine swap be made from diesel to a v-8 gas engine and be compatible?

j hancock Posted October 8, 2014 Share Posted October 8, 2014 Sure, with LOTS of time and money it could be done.Is the diesel no good? I would leave the diesel in the truck if possible.Probably would have to change the rear axle gears as well to work with the gasser. Quote JimIt doesn't cost anything to pay attention.

1958 F.W.D. Posted October 8, 2014 Share Posted October 8, 2014 No offense but why would you want to go backwards? If you swap it's usually a gasoline engine to an oil burner, not the other way around.And yes, there is an extremely high possibility that you will not only have to swap the clutch and transmission, but the rear as well. The driveline right now is set up for a max engine speed of 2100 (+/-) RPM's plus the higher torque of the oil burner. 1 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment https://www.bigmacktrucks.com/topic/37299-b67-engine-swap-to-v-8-gas/#findComment-262550 Share on other sites More sharing options...

Bigdogtrucker Posted October 8, 2014 Share Posted October 8, 2014 Sounds like a bad idea altogether,esp. the SM465! Quote Link to comment https://www.bigmacktrucks.com/topic/37299-b67-engine-swap-to-v-8-gas/#findComment-262564 Share on other sites More sharing options...

Popular Post 57 bcr Posted October 9, 2014 Popular Post Share Posted October 9, 2014 The gas engine will GUZZLE fuel to the tune of half the mpg (or worse) than that of the diesel! Unless your name is Abdul & you own several oil wells in the middle east, keep the diesel! If the engines bad,rebuild/repower it. You will be $$$$$$$ ahead. But after all,we are in a free country (for now) and it's your decision. My .02 3 Quote IF YOU BOUGHT IT, A TRUCK BROUGHT IT..AND WHEN YOU'RE DONE WITH IT, A TRUCK WILL HAUL IT AWAY!!!
