Need some help making a decision.
I have had my sons 88 Jeep 4.2L Project on old for a while but we are now starting to work on it. We almost just bought a newer one but decided we could just put some money into this one & come out better since we would know what we have
I live in TN & we do have emissions testing even though not as strict as many other states so I want his to pass of course.
We had decided to either go with the Howell TBI or the Mopar/Hesco MPFI kit. I was going to do the compression test to see how strong the engine is before deciding which way to go.
Now I have been offered a Professionally Rebuilt 4.2L engine with 4.0L Head professionally reworked with water jackets sealed. This also will come with complete wiring Harness & the MPFI etc.
Seems I will need the Dampener & maybe a fuel pump. I am researching to make sure of anything else that may be needed which is one of my questions here?
I also will not be giving a core so I will keep existing engine in this deal.
My reason for thinking of changing is Im not really that sure of the overall condition of the existing engine & with the cost of the Mopar MPFI as a factor I can just add a little more & replace with this rebuilt engine with the 4.0L head as well as MPFI which on the surface seems like a better approach. I have read here many times people giving advice for this setup or Strokers?
So what would any of you do in this case any advice is appreciated?
Everyone has an opinion & this is just mine sorry if it offends anyone.
