I believe edelbrock has stated that the core boxes went missing decades ago and they have zero intention of ever remaking. I have one on a 410 stroker, that I initially used the dual 4 barrel fitech EFI on, but later I switched to dual quick fuel 450s. Runs great, and I didnt bother with the...

That's almost NEVER the cause in my experience, and I do this every day. In my experience 99.9% of the time, its incorrect machining on the lifter face. I have the equipment to remachine lifters in my shop, and I will not install ANY lifter that I dont remachine first. In the past year alone I...

They probably wont be offset boring it once they find the factory bore locations are slightly off from blueprint anyway. The only way moving the bore is practical is to start with a block rough bored well below your finished dimension. Like a race block. Not a used oem block. Even then, the...

You will find numerous posts by the op, which follow a similar theme.

That thing is bad-***! If that's a **** box, I wanna buy a few of em

I believe your math is off. A iron slant is not light by any means, and if it's a stock slant, it will have about 105 hp.

Yup, shitty move there. Douchebag

Your going to be removing all that stuff

The only experience I have had with BB speedmaster stuff has been the victor knockoffs that use offset rockers. Those are a disaster. I've never used there conventional BB rockers on anything.

I would think it would have sold allready at the asking price if it's legit on the vin numbers

Another thing of concern, the pictures from underneath dont show the torque box areas. Could be lazy picture taking or could be purposely cropped out. Who knows. There are a few other things to verify, to confirm its legit. Buyer beware! It appears to be someone's unfinished project, with "barn...

I think its extremely obvious it's been painted underhood, and underneath, zero question about that. One thing I wondered about, is this area of the pass side inner fender. Was this a 72' up thing? I dont remember seeing that on earlier cars. Probably for the charcoal canister mounting.

The headers will bolt right up to the magnum heads, and the flywheel, bellhousing and all is a direct bolt up as well to the 5.2 magnum

Strip the parts off the 273 and throw the block in the scrap bin. The 5.2 magnum is superior in every way.

That's a $100 core in my opinion. The fact it's been "remanufactured" actually detracts from the value, because it COULD allready be .060 over.
