james j neiweem Posted July 29, 2020 Share Posted July 29, 2020 (edited) And don't forget that the original mack engines were gasers such as those in the Mack Ab's and AC's. I am not sure what their designations were. Before my time but not by much.🙂 Edited July 29, 2020 by james j neiweem 1 Quote Link to comment https://www.bigmacktrucks.com/topic/11233-mack-gas-engines/page/3/#findComment-457033 Share on other sites More sharing options...

Robert J. Walla Posted July 14, 2023 Share Posted July 14, 2023 I have a Mack 707 Gas 6 cylinder I am putting the finishing touches on. Complete overhaul with sleeves. 5 inch dia pistons. It's a hoss! The FDNY speced 23 of these in 1953 and mated them to a 1000 GPM Hale pump to pump into the high rise buildings of Manhattan. LS 1113 is single ignition, I'm figuring the gas will cost as much as the overhaul.
