How durable are stroker motors?
Posted: April 22nd, 2018, 11:48 pm
Hey guys, newbie here! Let me start off by apologizing for me
being here. I am not a gearhead, i dont understand any of the
technical aspects of building a motor of any kind - might as
well be all Latin to me... (in fact i think one of the threads i just
read here was actually written in Latin...)
But i digress. I have an 88 Mj that i am in the prep stages of a
complete restoration. Im trying to keep it as factory-appearing
as humanly possible, but the end result is going to be a jeep
i travel cross-country in. Highway speeds, different terrain,
11+ hrs at a time are certainly all possible. It will also need to
deal with emergency flood conditions, but no rock climbing.
The truck as its original 250k Renix 4.0L which is not up to the
task. The motor and wiring harness will be removed. My plan
was to swap in a complete 1991 4.0HO drivetrain from a donor
and simply rebuild/replace the motor. I was told repeatedly that
the 4.0HO was the way to go because "the 4.7 stroker could not
handle those kind of driving conditions." For the past 3 years i
have been collecting the nessecary parts for this swap.
However. Last week when i started asking questions about the
swap, everyone told me that the 4.6L stroker would be far better
suited to handle the kind of driving i want to do. Now i find
myself in a predicament - i have a running Renix and a running
HO both ready to be rebuilt, but if a stroker can handle the
endurance i would need, seems only logical to go that route.
The guys at the comanche club said to come here and ask -
money not being a concern, should i rebuild the HO, stroke
the Renix, or Stroke the HO?
