1963Mack Posted June 30, 2008 Share Posted June 30, 2008 Did Mack have any problems with the 864 V8 motors in 1964? Any block cracking, head gasket problems? Are they hard to get parts for?Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/3941-864-v8-in-a-1964-dm815sx-w-quad-box/ Share on other sites More sharing options...
v8superdog Posted July 12, 2008 Share Posted July 12, 2008 i am gettin ready to buy a 1971 R700 with the twin turbo 864 V8 and I asked my dad who is an ASE master technition and has been working on nothing but Macks since 1970 about that motor and he said it was a head gasket blowin' son of a gun. He said it was because the head were not fire-ringed is the reason it blew the head gaskets so easy. I am gonna have the machine shop fire ring the heads on mine and i will probly put main girdles in it as well. hope this helps good luck Quote 1993 Mack CH613 350 V-mac complete with Blixxton II module, RTX14710B Fuller tranny, 4.17 ratio 38K camelback rears, converted to 5-axle dump truck in 1999.

ThaddeusW Posted July 12, 2008 Share Posted July 12, 2008 Never mind the gasket blowing. First gen 864 v8 parts are becoming as hard as to come by as hens teeth. Better baby that v8 for shows.
