2007 Jeep 5.7 dropped vlv seat have to Bore
Im new here, I have an 07 5.7 in a Jeep Commander.
Long story short it dropped a Valve in #7 cyl and did a number on the Bore.
I bought it this way I never heard it run just Hauled it home and tore it apart.
Head is trashed, Bore not much better BUT My machinist says he thinks I can get a 6.1 Piston in it?
I have spoken to a few suppliers they say no adamantly, while what I read says Chrysler did this to make the original 6.1s to begin with.
I spoke to Scat about a Piston and a stoker crank depends on who you speak too there but will sell you anything you want.
I also spoke to Hughes who says NO! cant bore it that big But again will sell me the parts.
I want to bore it to a 6.1 4.055 with a stroke of 4.050 BUT I don't need over heating issues as I live in Death Valley.
I also wanted to install the Oil squirters the 6.1 has But the guy at Hughes says cant be done with the stroker kit, crank will hit????
I have already purchased set of Eagle heads and had them rebuilt springs for .600 lift.
I also have purchased a stock Aluminum Intake from an SRT.
Looking at Howards cam # 786155-14???
Comps cam 112-500-11????
either way Use Comp Lifters 856-16?
Also looking at a set of full length Headers for an SRT8 Jeep Grand Cherokee as they dont make headers for the Jeep Commander.
I have NEVER built a Hemi before looking for advise ?????
I want a Good Truck engine to go out on Hi ways and Hill climbs 4x4 in the mountains Needs to have loads of Torq and be reliable and run on Pump gas and live for another 150K+ miles. Non supercharged no NOS no Turbos no racing just pulling and 4x4ing
Thoughts? ideas? advise? Many thanks in advance!
Credit cards are burning a hole in my pocket on this one.
