Mort Posted November 28, 2012 Share Posted November 28, 2012 What is the max revs that a 350 can be taken to downhill? Quote Link to comment Share on other sites More sharing options...
Lmackattack Posted November 28, 2012 Share Posted November 28, 2012 2300 RPM (if my memory is correct of the shop manual). however that is the suggested max rpm. our sled pulling truck turns about 2600 with stock heads. someone had said old stock valve springs start to float near 3k RPM 1 Quote Link to comment Share on other sites More sharing options...
rsb502 Posted November 29, 2012 Share Posted November 29, 2012 The old ones do a lot better than the newer ones, the aset AI engines had an issue with the ceramic rollers on the cam over 2100rpm they would bounce and crack then run the cam down, happened on a bunch of 04-06 trucks here drivers would over rev em on hills and kill em.

mowerman Posted November 29, 2012 Share Posted November 29, 2012 not really good to run it past 1900,,,less your shifting..bob Quote Link to comment Share on other sites More sharing options...
rsb502 Posted November 29, 2012 Share Posted November 29, 2012 I hope nobody is shifting past 1900 rpm, Thats a whole lotta revs, even if you had a 5 spd it still seems high to me, I prefer the low rpm smooth shift to the wind er till she pops shift!

Vladislav Posted November 29, 2012 Share Posted November 29, 2012 I wish I know revs I'm shifting.The truck that runs has tacho out of service.The other truck has, but it can't run.Will look a sensor of a flywheel although at a warm time.
