It's got the 6.6L V8, the 351-400 engine. Stock I think it was 133hp but this was muscle car era and this has a ton of torque, it has no trouble towing or hauling (provided you can keep it cool!) But apparently the engine was worked over by a previous owner, built hotter than usual with a Holley 4bbl carb and some other bells and whistles. It'll be a while before I can drive it (I have the whole dashboard torn out to restore it) but I'm tempted to dyno it to see what it can do.
Today I installed the "cheat code" of lesser engines: bigger tires than stock. It's only a 1.5" difference but every little bit helps.
Dang! Lookin' good! I sure wish I had that 383 for my '90 burb. I have a horribly underpowered crate 350 in it now. Just had it put in about 4 years ago. Wish I would've thought through that more at the time...someday I hope to put one of these puppies in there!
Going to start doing body work on my '68 burb here soon, too. I've never done body work, but I have a neighbor that wants to show me how to do it. Can't beat a deal like that!
