Nathanwhit1 Posted 7 hours ago Share Posted 7 hours ago Evening all I’m just starting with the rebuild of my E6 after a little big end issue. I’ve heard the E6 came in a different range of hp from 250 I think up too 350. What did they change on the engine to increase the hp ?

Joey Mack Posted 5 hours ago Share Posted 5 hours ago I just went through the book i have, and i didnt see anything that showed different part numbers for different horse power ratings. I think that turbo, nozzles, and injection timing may be where the difference is made. But im not at all smart about E-6' s Quote Link to comment https://www.bigmacktrucks.com/topic/75776-e6-engine-horsepower/#findComment-578857 Share on other sites More sharing options...
fjh Posted 5 hours ago Share Posted 5 hours ago When the engine went to 285 315 they added the air to air box which you have and the web’s between the main bolts which u also have ! 350 they added a water cooler section to the aftercooler ! There may have been some piston changes I am not aware of and also governor / fueling changes!

fjh Posted 5 hours ago Share Posted 5 hours ago Just now, Nathanwhit1 said: Do you have any pics of the water cooler etc ? No sorry bro I don’t! Your core engine is fine you can go up to 315 with that ! The water section used to take up about 3 inches on top of the existing air to air !with a 1 inch tube in and out ath front of the box!

Then again, I remember when a 350 was like the greatest thing (lol)......n they kinda were at the time My 300+ has the flip flop linkage going to the pump so it can push instead of pull. A new local FB friend pulls using a 285/300 and removes the intercooler in an R model. Apparently this pump is " the pump" to run . He turns it like 3000+ rpm, all stock bottom end.
