roadranger Posted December 2, 2022 Share Posted December 2, 2022 Did the RWS-700 built 1977-1985 have a 855 cu. in. Cummins engine available? And at what HP ratings? This model was built in Macungie after Hayward was closed, 6,584 units. Maybe some had an 855 Cummins in it?

880joe Posted December 2, 2022 Share Posted December 2, 2022 Yes Cummins was an option. Not sure on hp available Quote Link to comment https://www.bigmacktrucks.com/topic/70805-r-700-question/#findComment-516863 Share on other sites More sharing options...
yarnall Posted December 3, 2022 Share Posted December 3, 2022 The RWS766 has a 400 in it. Quote Link to comment https://www.bigmacktrucks.com/topic/70805-r-700-question/#findComment-516976 Share on other sites More sharing options...
Bullheaded Posted December 3, 2022 Share Posted December 3, 2022 My 1978 full line brochure shows the R700 available with NTC Cummins up to 350 h.p, both regular NTC and Formula. It only shows the 400 and the KT's under the Superliner and Cruiseliner. But a 350 can easily be made in to a 400 anyway. The R700 also shows Cat up to the 3406 DITA 380 and Detroit up to the 8V92TA 435.

Bullheaded Posted December 3, 2022 Share Posted December 3, 2022 Interestingly in 1978 it doesn't show ANY Mack engines in the R700. Quote Link to comment https://www.bigmacktrucks.com/topic/70805-r-700-question/#findComment-517063 Share on other sites More sharing options...

This makes me want to ask if there is a GVW difference between a 600 and a 700 series truck or did ALL 700's have nonMack engines / powertrains???? Obviously you could spec a 600 series for different GVW's so I presume the 700's were the same????

Bullheaded Posted December 4, 2022 Share Posted December 4, 2022 I only had the R700 brochure from 1978 so at least that year had no Mack engine listed. But yes I have seen them with V8 Mack engines.

dockmen027 Posted December 14, 2022 Share Posted December 14, 2022 In the late 1970's AR Gundry (then owned by Refiners Transport) and Gypsum Haulage, two Leaseway Transportation Companys shared the same terminal in Albany NY. Gypsum started out with used Whites from other terminals but eventually received at least 10 brand new R-700's with 290 Cummins and 9 speed Roadrangers. They were some beautiful tractors....average fleet power for back then.

mowerman Posted December 14, 2022 Share Posted December 14, 2022 We only had 230s in our whites we would have been pissing ourselves for the 290 lol yes I imagine they were real nice Bob Quote Link to comment https://www.bigmacktrucks.com/topic/70805-r-700-question/#findComment-518261 Share on other sites More sharing options...
