88RD688S Posted September 10, 2016 Share Posted September 10, 2016 Hello, I have a ReMack 350 2valve in my 88 RD triaxle dump. It has cracked exhaust manifolds and I was hoping to replace with something that will flow better than factory manifolds. Had the injection pump rebuild last year and turned up around 10%. Right now it seems that the egt climbs very fast and won't let me hold the rpms and less than 1800 on a long pull. Anyone have some ideas or comments. I would like to put some superflow injectors in at some point but I don't want to waste the money if the high egts will be a problem. Thanks.

fjh Posted September 11, 2016 Share Posted September 11, 2016 Have you checked for boost leaks ? Is your air cleaner fresh? Quote Link to comment https://www.bigmacktrucks.com/topic/46793-2-valve-350-high-egt/#findComment-345335 Share on other sites More sharing options...
