jeffmackb Posted March 7, 2013 Share Posted March 7, 2013 This might seem petty to some here, but the Twin Turboed END864 is not an ENDT864, it is an END864T.Later engines were ENDT's, but not the 864. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/30286-mack-v8-s/#findComment-170345 Share on other sites More sharing options...

Gmerrill0516 Posted March 8, 2013 Share Posted March 8, 2013 My truck had the 864 and I believe it was rated 255 HP. Its long gone. I understand that the injector pumps were a funky design and prone to failure and are now scarce like hens teath.

39 Baby Mack Posted March 8, 2013 Share Posted March 8, 2013 My truck had the 864 and I believe it was rated 255 HP. Its long gone. I understand that the injector pumps were a funky design and prone to failure and are now scarce like hens teath.The first 864's used PSJ or PSM Ambac pumps which were single plunger pumps with a distributing head on it like a distributor.Later ones used APE style pumps APE8VBB, this when I think the normal H.P. rating went from 255 H.P. to 270 H.P. These were multiple plunger pumps and looked like a little baby V-8 engine sitting on top of a big V-8 engine!These motors also used a later style intake manifold.I don't think, or would know how, these pumps would have ever been used on the turbocharged 864's. There just wasn't enough room, I think they were all built with the single plunger pumps.On another V-8 note the first N/A 864's had an aluminum tube that joined the two intake manifolds together, the ports for this tube were located on topof the intake manifolds in front of where the fresh air ports were.These were balancing tubes to provide for "smokeless operation"There were also two different sets of these tubes low ones and high ones! When they made the ENDT-864 they used the same early manifolds and used plates to block off the ports.Ron 1 Quote Link to comment https://www.bigmacktrucks.com/topic/30286-mack-v8-s/#findComment-170491 Share on other sites More sharing options...
REOGasMackDiesel Posted March 8, 2013 Author Share Posted March 8, 2013 280hp@2100rpm ? ! So they the V8s ran about the same rev's as the I6s ? !Meaning both hit peak HP@2100 ?Mike Quote 1953 REO M48.1962 GMC 3000.1969 AMC AMX-390.1983 AMC Eagle SX/4.1988 AMC Jeep Comanche.

39 Baby Mack Posted March 8, 2013 Share Posted March 8, 2013 the 865's were rated at 2400 rpmMike Thanks for posting I didn't know they ran that fast. We never had any, we were through being guinea pigs by the time they came out.We had five F-715's with N/A 864's, five 400 series Brockways with V8-265 Cummins, six 400 series Brockways with 8V71 Detroits, and one F-719 with the turbocharged 864.After that we came to the conclusion that the best V-8's were the ones that came in cans and contained vegetable juice!Ron Quote Link to comment https://www.bigmacktrucks.com/topic/30286-mack-v8-s/#findComment-170598 Share on other sites More sharing options...
Superdog Posted March 8, 2013 Share Posted March 8, 2013 I hate to doubt the museum,but as I said when that sheet was first posted,there were a whole lot more 719's built than 34.If there were only 34 ENDT864's made,what did the other 719's have for engines?????

39 Baby Mack Posted March 8, 2013 Share Posted March 8, 2013 I know what you mean Mike,Our "F" model was F719T-1093 that would make it the 93rd one made.There's got to be something wrong with that list.Ron Quote Link to comment https://www.bigmacktrucks.com/topic/30286-mack-v8-s/#findComment-170622 Share on other sites More sharing options...
REOGasMackDiesel Posted March 8, 2013 Author Share Posted March 8, 2013 The above photo shows 280hp@2100rpm ? !It shows 700tq@1600rpm ? !So it looked like the torque is up in the revs but the HP was shown as to be at 2100rpms . . . So I had to ask ;o)Mike Quote 1953 REO M48.1962 GMC 3000.1969 AMC AMX-390.1983 AMC Eagle SX/4.1988 AMC Jeep Comanche.

Jacob Hudson Posted March 14, 2013 Share Posted March 14, 2013 I have an M123A1C with a V8-300 Cummins. It is a '68, so it was when Mack went back to producing them, after CONDEC had taken over that line for a little while.
