Thanks. I have an '06 now, with the 460. It works well for what I do, which is grain/feed with an end dump. Most times hauling at 62 and 63 tonne.

found this '97 available in Florida. The truck has had a number of cool fix ups and thought it would be good to have for summer time, while running the 06 in winter.

i had read in this forum that the 454 was doggy ( no pun), but most of the Mack mechanics say that going to a truck in late 1990's is a safe move.

Around the  700k mark. Well cared for truck by an o/o.

i have heard that the 454 was not as strong as the 427 hp?

hope to get some feed back.

Looking at a 1997 CH613 with a E7-454hp. Looking for the good the bad and the ugly on this power plant.

Morning all.

i am changing out the thermostats on my vision with the 460. I've got them out, but am thinking the rear air to pipe will have to be loosened or worse removed? 

Any ideas?

Thanks
