Idea for new engine
Hello new to the site, I just have a couple of questions regarding converting my 1976 GMC sierra with a 350 in a 6bt diesel burning monster :)
1) What are the appropriate steps or little things I need to be aware of, I will be buying a donor truck but I plan to put in a matching 5 speed NV4500, it is a 2 wheel drive truck. What are some problems I might run into regarding hook up? I do currently have an automatic and I know the complications in switching to a CHEVY manual, but not a dodge. 2) I do not plan on going faster than 55mph unless I have to, max is 65 on freeways. My question is, what is the appropriate RPM for a diesel at 55mph, is 1800 too high? I have a dana 60 rear end with 4.10. Partly my reason for going NV4500, I know a diesel would not be happy with a th400 and 4.10 rear gears. I will be using 31" tires, but I will not be afraid to buy 35"tires to keep the rpm's down. I will be towing from time to time seeing as its a truck, I would go 4bt execpt its a C2500 and a 4bt might be a little small if I decide to tow. Thanks guys! Cummins :rocking: |
1) It should be the same for either a Chevy or Dodge manual. Crossmember, driveshaft, clutch master cylinder, and clutch pedal will need to be changed/installed/adapted/rigged.
2) No 1800rpm will be just fine at 55mph. With an NV4500, 31" tires, and 3.55 gears it should put you right at that, with 4.10's it will be considerably higher. |
Thank you! I will probably have to put bigger tires on my rig, but no big deal, I need the lift anyway to clear the oil pan. Not to mention the gas mileage will be better either way. shooting for about 20 on the street, an improvement from 8 :P

Not a problem! Any more questions Ill do my best to answer them.
And same here I was getting around 16 before the swap, averaging 23-24 now, and 27-29 highway :c: Im about to potentially get some 3.27 gears put in (3.55 now) and hopefully hit over 30 highway :choochoo: |
