Is there a 12-14 litre straight nat gas engine available now that can be installed in any 10 year old Semi and mated to a 10 speed??? Anyone know..??
menards trucks do run natural gas in some, but a driver told me they don't pull anything over 60k well at all and there in the shop quite often.. Maybe you can see if there selling one?
Imo, the most popular NG engine here is Cummins ISLG, but the most powerfull is ISXG. Old NG engines were gutless,I' sorry
