Saw this:


(original article):

The 350 CID V8 that has been wedged under its hood was intended to give the car some actual poop. The car’s original engine was the lamentable “Iron Duke” (or Iron Puke) four and being saddled with that motor in almost any car is like going to a make-out party when you were in middle school and getting paired with the kid wearing headgear. The V8 is an appreciable upgrade as its estimated 220 horsepower is more than double the output of the original four-pot.

The conversion was done by someone described as a GM engineer who, according to the Pontiac Enthusiast story, sourced the V8 out of a 1992 Chevy pickup truck. The transplant took six months to complete, with probably a good deal of that time figuring out a mid-plate between the big engine and the punky little THM-125 three-speed automatic that came with the car. Obviously not up to the task out of the box, the transmission received additional clutch packs, enlarged oil passages, and aftermarket valving to keep up with the V8’s output.

The over-abundance of speakers (in the door) is a bit much), but otherwise, yeah. My dad a 6000 as a company car, with the Iron Duke. Then my neighbor had a 6000 wagon with the 2.8 v-6.

That red velour cloth though.... man I miss those days of being able to slide in and generate static.

I loved 6000's. We had an LE somewhere down the road, but I always wanted an STE.

THis would rock.

I've seen this pop up a couple times over the past few years. I've always wondered how much that transmission could handle. 220hp isn't a lot but it's more than double the factory output. You think it's reliable?

As long as you're not standing on it from every stop sign it'll probably be okay. The thing is 30 years old. I would hope that at this point there would be a manufacturer that made a suitable replacement that could fit and handle the power.
