  1. If you are still looking for this info PM me and I'll send you scans from the manual.
  2. Thanks for the replies guys. Been around trucks all my days but am a very recent convert to Mack, we don't have many of them in Scotland but since coming down to NZ have been pretty much surrounded by them. I have been working mainly on Kenworths, Internationals and what the Japanese call "trucks" (Nissan, Isuzu etc). Cummins, Cat, Volvo and Scania are my speciality so I dont know much about the Mack motors, hence my questions. I only recently bought the R series and am growing rather fond of it, once I get it the way I want it I will hopefully be using it most days as a working truck so want a good strong reliable motor in it. I do prefer a "mechanical" motor but have no issues putting an "electronic" motor in as long as its a good one. I was looking at a 454 but was told to leave it where it was as they are bad for heads. Ideally I would like around 400hp but would settle for 350hp in the mean time! I do have an idea concerning a 450hp Scania V8........ Mutt.
  3. Hi, Just been offered an EM7 300 from a 1993 CH 600 at a very good price and would like to open it up to around 350hp to put into my R series. Are they a good motor or am I better rebuilding the E6 315 and sticking to it? Any comments/help is greatly appreciated. Mutt. If anyone needs any workshop manuals let me know.
  4. Project Truck. I will update pics as it goes along.
