The Bad. Convertible Top has a few rub holes but functions great. Paint has a few scratches, urethane body parts have some cracks. It's a good base body for a complete vinyl wrap that the new owner can complete.

I didn't think I'd ever see the day! I remember following the build on this back in the day. How's it looking now that it's finished up?
 
Well I said I would make it look good after it ran good... It's been running great for 10 years in it's current iteration but I can't see myself spending thousands for a vinyl wrap. Too many toys and this one just keeps accumulating scratches from being in my small garage. It's posted on a Vortec 4200 swap group that I stumbled on recently. There are quite a few people that are enamored with these oddball engines.
 
For sure! I love it, being different while also performing well! I considered using one in my Sonoma after you started the build. I even had the core out of my old Envoy I could've used as a starting point. But I already have 2 5.3s in the garage waiting for it.

Whatd this thing ever end up putting down?

Yeah it's limited by a 1 bar map sensor so that's as quick as it's gone at 3800lbs.. 10.85 126. It runs mid 12's on WasteGate pressure 7psi in the summer heat which is really all I wanted out of the combo from the start. I have a spare engine because we didn't think it would hold much boost but but it's been great. The 4L60 transmission is kind of a limitation also.
 
any mods done to the structure that would hinder you from putting a 305/350 back in it "easily"?

That seems cheap as fuck to me for a body style that is so sought after right now.
 
I'm nearing the "part out" price... I welded the new solid engine mounts to the factory K member. To put a V8 back in would just require you to cut off my solid mounts and bolt stock V8 mounts back on the k member. The list of aftermarket parts on this car is long.. I'm open to offers.
