Gurney Posted December 26, 2023 Author Share Posted December 26, 2023 It was a 300 plus engine. I am now going to sell it. I now have 5 Oshkosh MTVR military trucks and I dont have enough room to keep them all. I have more pictures and videos.

Yottagenew Posted June 28 Share Posted June 28 (edited) When it comes to the engine size in the '65 Mack B53, you're looking at some classic muscle under the hood. Back in those days, Mack trucks were all about raw power. The B53 usually packed a punch with its big block engines, like the Mack ENDT-673 or the ENDT-865, depending on the model. These engines were built tough, meant to haul heavy loads without breaking a sweat. If you're into restoring or just curious, checking out sites like https://ruler.onl/ could give you more details on specs and maybe even some tips on maintenance for these old beasts.
