Sorry, I am new and now I think I should have posted this in the Basic Forum. IDK
I have a 1996 4.0 and I am building a simplified 4.5L Stroker. I will use the Jeep 4.2L 3.895" stroke crankshaft and the 4.2L 5.875" rods.
This is what I have now:
8.5Wires/AccelCap&Rotor/RemoteOilFilter&Cooler/3CoreH.D.Radiator/FlowKoolHiFlowWaterPump/TurboCityHiFlowThermostatHousing&Thermostat/9"K&N Cone/62mmThrottleBody/04IntakeManifold/BoschFuelPump/WrappedExhaustHeader/2.5"CatBackExhaust
I want to use Venom High Performance Fuel Injectors 24lb. for Ford V8. Python high performance injectors have a 10 percent higher flow rate than stock injectors, so they boost horsepower without creating an overly rich fuel mixture. As a result, they are supposed to enhance overall performance while maintaining an optimal idle condition.
Since I have a '96 4.0L and not '93 or earlier HO, can I use the WH825CP Pistons instead of the W677CP Pistons? For a '96 4.5L Stroker what would you suggest for Pistons?

with

Or

Any and all helpful comments and suggestions are appreciated.
Thanks

Re: Modifying my 4.0L to 4.5L Stroker i.e. Pistons
I used the 825cp30s in a 94 block in my 96. If the bores look good and you want a stock size piston, go for it--might need a light hone. I had the block decked .030" and the head .006" and used the felpro 9076pti .051" hg. If I built it now with the same parts, I would zero deck the bock(decked .040-042"), have the 825s dished to 20cc, and use a thinner head gasket(the mopar [email protected]").
