ThaddeusW Posted March 5, 2009 Share Posted March 5, 2009 Grant I assume it has a Maxidyne 237 or 300 tip turbine? On my 673 the numbers are stamped on the front gear housing on top of where the injection pump mates to it. If its a V8 then someone else here would know. I hope this helps.Numbers are almost invisible but you can make out the EN part. Quote -Thad What America needs is less bull and more Bulldog!

If it came from an 'F' it could be on the back of the block just below the head. If it was a V8 it could be on the pan rail, just above the sump pan or across the top at the back of the block below the valley. Tell us what you find. Regards Jeff. The pan rail drivers side (OZ) about the middle.

HK Trucking Posted March 8, 2009 Share Posted March 8, 2009 An R611 would have originally been equipped with an ENDT673C Thermodyne @ 250H.P.The outward appearance of the ENDT673C is identical to the ENDT675 237 H.P. Maxidyne, except that the ENDT673C would have been a light greenish blue color, and the ENDT675 would have been Gold.(edit to add: Also look at the top of the valve covers, back then they were marked "Thermodyne" or "Maxidyne" on that flat area on top. That could tell you what it is, unless someone put different valve covers on it at some point) Quote "If You Can't Shift It Smoothly, You Shouldn't Be Driving It" Link to comment https://www.bigmacktrucks.com/topic/8542-flintstone-260-engine-number/#findComment-31878 Share on other sites More sharing options...

I think they are identical engines internally. Maybe someone knows otherwise. Regards Jeff...... Maybe they have different injectors aswell.

The C motor was a completley different engine to the Maxidyne. They had different pistons smaller gudgeon pin different rods bigger weights on the crank. the touque was at 1500 fuel settings were completley different. You could fuel them up a bit but they were a fragile motor as to the maxidyne . I had my C motor with 10% across the the range but kept the touque at 1500. It would hold it's own with a 290 cummins and give a 903 a good run for it's money. I certanly would not try to make a C motor into a Maxidyne you would kill it.

I've heard over the yrs blokes saying that engs have been rebuilt to Maxidyne spec and I was thinking they were internally the same. Regards jeff.

Jeff Yes I am pretty shure it was Hayes, candy apple maroon coulor Didn't take a lot of notice it could have been a 700. somebody said it was rolled over. Used to see it come up the coast loaded with timber. I think they had a W model with a V12 that suffered the same fate. Never could check it out it was always too fast.
