Unfortunately I don't know much about the engine. It's lopey as hell, though. The guy who had the car before me worked at a performance shop, and took the 390 from a 69 AMX and built it up for this car. He punched it out, just like AMC did, to get around a 401 or so. I know the think has a wicked amount of power. I've cut the rear loose with full throttle at 45-50 MPH on those 275 or 295 tires (I'd have to look again) on the rear, so there's power there for sure!
It needs tuned badly. The car sat for a few years with me changing the oil out every 6 months and turning the oil pump over to prime everything, then cranking it for a few seconds to get it all oiled up. But the carb is out of whack. I replaced a leaky fuel feed line in the engine compartment and added some good gas, and she started right up. Takes a little coaxing if I let her sit to get started again, but after that she runs until I turn her off, or stall her. A good rebuild on the holley 750 (I think it's a 750) would probably fix that right up.
I've driven the car up and down the street, and she runs just fine. The electrical system is a bit screwy, the headlights don't work, but I'm 85% sure that the wire just isn't hooked up in the dash when I started reassembly to get her out of the garage.
I bought the car basiclaly because I love the body style, and I wanted a real muscle car beater to drive around. I did so, until the starter went out, and she went into the garage. I replaced the starter and various parts, and just got busy with other things.
If you're at all serious about the LS6, I might be willing to throw in some money with the car. I don't think a 5.3 is going to cut it for what I need, unfortunately.
And thanks for posting!
