Superdog Posted September 9, 2013 Share Posted September 9, 2013 My R615 is a 1967 and it is R615LST1213. I'd say '67 is a good bet,only 27 apart. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/32692-rare-r-model/page/2/#findComment-204970 Share on other sites More sharing options...

hossein Posted September 9, 2013 Share Posted September 9, 2013 Good observation. This truck was built before the tip turbine was introduced. The purpose of the twin intake is to allow the driver to choose between hot or cold air entering the engine. Only one pipe is used at a time.Thank you.

Green Dash Posted September 9, 2013 Share Posted September 9, 2013 No intercooler yet, tip turbine came out in '73. What this is one tube connects to the intake the other is just to draw warm air from under the hoodMy bad. I didn't see that you covered that already.Good observation.
