Don't want to step on any toes here, but I have torqued a girdle onto a regular 109 block, & seen the block distort as it is tightened between the block & the girdle.
I should mention that at the time I had a standard bore 109 block, & a standard bore SGI block & was asking the same thing myself.
So I torqued the girdle on the SGI block & there was a big differnce in the distortion of the block.(SGI better)
GM put more meat around the bottom of the cylinders in the SGI block.

As far as I know the stage I is more closely related to a stageII block than a stocker. Way more material in the main webbing, can be drilled for 4 bolt mains, cam moved higher in the block to clear stroker cranks, and all around beefier. Looking in the Buick Powersource book, it also weighs a bit more than a 109 block. It's been a long time since I've seen one but I think it has the material there for the extra head bolts too. I've heard it's basically a stageII block minus the extra machine work.

Well that definitely clears up some questions about my block. Thanks for the replies!

So I take it that means you got a SG1 109 block? I'm looking forward to seeing your car at the Bradenton event! Maybe you can beat out Louie for having the fastest Hartline built stock block (TSM) car
