Also, those guys modding the diesels seem to be placing a lot more strain on the engine and contributing to reliability problems. I've never needed more power or more speed in the SMB or my trucks. I have a sports car for going fast. YMMV
You may not be understanding my needs bluedog. I'm not looking for a sports car out of my van.
I will be pulling a 22' trailer much of the time.
IMHO the V10 is confused.
A big block should have torque. I'm sure the V10 torque numbers are decent.
But why a big block
has to spin like crazy to pull decent is just odd to me.
I hear thats how it runs.
My V10 dogged pulling a medium size U Haul trailer (maybe 2000# loaded with furniture) over Tehachapi pass.
Ok it did 60-65 over the pass... at 4500 rpm!!??
That is stupid rpm for a pulling rig (which mine is).
I would like to get that extra 30 lbs of torque or hp and
do something about shift points.
My travel trailer is 4500# dry.
my E350 will not shift entering a freeway without letting up slightly on the accelerator pedal.
Loaded or in tow/haul mode it just will hang in a lower gear, rev to the moon and not shift.
(I think I have figured tow/haul is mainly for holding a gear and speed on downhills.)
When I do let off, get it to the next gear, it does pull, without bog.
It will do it.
I am not trying to mod the internals of the motor. Only open it up slightly.
There is power to be had out of most vehicles these days just with computer/chip tuning.
I'll check with my dealer and see if there are any warranty issues with chips or re-calibrating shift points.
I think I have seen the instruments to tune my motor.
I guess I am looking for that west coast tuner.
Yes I will search the Seattle area locally.
