Mike, that would have been ENDTF @350hp and most likely the F is for firetruck. Then there was an ENDTI @255hp which is also what the standard naturally aspirated 864 was rated at. Also an ENDT864A at a whopping 355hp. It appears the standard EMDT864 was @325hp.

The papers I have on the history of the Mack V8 shows the ENDT864 (note there is no double T?) was used from 1965 thru 1972 with 4 different versions of the ENDT for a total of 661 built. I assume they were all twin Turbo'd. Surprisingly they built over 7600 of the naturally aspirated 864's and they were offered along side the 865 and 866's for 3 plus years. I sent off a request to the museum to verify if they would have installed a few earlier than 1965 as you would assume a few were out there for testing. The late Bob Brown told me that when he was the northwest Mack service manager they shipped a few up to Alaska for trial runs and he thought it was an awful idea as they were constantly broke down as they worked out the bugs with them. It seems that was in the very early 60's in F models.

I don't think Mack ever designated the V8 B series with a 3 for turbo. Here is one that was at Lexington that had the factory installed twin turbo'd V8.

what about the B-7553........or an 864 twin turbo?

Wish there were more pictures of the PA Steel haulers with the 3 axle 32Ft trailers and a big coil. See very few??

did that truck originally belong to John Cheeseman out of Ohio? I believe Tom Spencer restored on for him.

I am learning that lesson right now as I rebuild 2 E-9's!

Damn it Larry we gave it our best! It was fun seeing you whisked away in the golf cart...........maybe it was more than your truck she was hoping to write about?

The H model made the Brooks run with no problems. It just always makes me laugh about big power today. I passed him like he was standing still climbing the mountains out of Grants Pass with the Superdog KTTA but just one extra pull over to catch a coffee to go and he arrived at Brooks (235 miles) within minutes of me. On the way back he pulled the Ken Talley Cattle Wagon that we use as our bar and grill. Sure looked good.

I have seen Harry at a few ATHS shows since he sold off his collection although not for the past few years. He just took a negative view towards owning restored trucks and sold them off. The Roadway H model and the KW conv both at Keystone now were and are exceptional.

yes it was

tri plex and it is hard to believe looking back riding with my Dad in his 57 H hauling one big steel coil on a 32ft triaxle trailer. Going up a long grade he'd have a cigarette out the corner of his mouth and both hands on the shifters. He'd get it all the way in low and that truck would just rear up and I thought it was the coolest thing ever. Now thinking about those hot muggy summers in western PA and him on the way to Newark, NJ. Tough guys then!

This truck hasn't seen many miles in a lot of years. A friend who started driving in Virginia in an H model wants to drive it up to the Brooks, OR show in a few weeks so I decided to get it serviced and make a run. It performed well other than the sticks are awful stiff. It will be a hot 270 mile run but a lot of fun and memories. Note the smoke in our valley................plain awful for 2 weeks now.

in the NW mountains it was for snow building up in the horn!

yes they do and someday I want to get one restored. Both were bought "new" by Haney truck lines
