Dodge Repair Questions? Ask a Mechanic for Answers ASAP
I could be wrong but I understand on these older models that are not chiped. that you can bump or adjust the pump just a little for more power. dose that make sense to you and did this answer your question. ?
Thanks. I do not like to recommend or suggest a method of timing adjustment to gain power as this deviates from factory specs. I am not saying it can /cant be done, but i will leave the call in your hands. below are instructions for setting the pump timing. You can tweak it as your preference. I do suggest if you do any rotoation of the pump to bump timing, you put a very clear mark on the pump
CAUTION: The timing pin is positioned by the manufacturer during engine assembly, to correspond with TDC of the compression stroke of number 1 piston. If the timing pin or gear housing is removed, the timing pin location will not be correct when reinstalled. Set the Fuel Injection Pump-to-engine timing gear timing. ADJUSTMENT PROCEDURE
This would indicate that the plunger lift of the injection pump was 1.25 mm, and that the injection pump timing does not need to be adjusted.
no, this is not a dumb question at all. I am not saying you can not teak the timing advance slightly. It is just my job to give accurate answers per original setup as to avoid possible problems. there is a site shown below that specializes in performance mechanicl pump items to help gain 20-40 Hp in the Cummins engine. you may want to call them and ask what would be best approach.
