Good luck.... I have one std bore... but it took a ridge reamer to get the pistons out.... those carb'd cars wear the cylinders out faster IMHO.... I guess all that gas... keeps the oil off the rings... and makes the friction higher.... Mine is going back .030 over..... Just my theory.... Oh... the SG1 motor I found.... had a std/std rolled fillet (rods and mains) crank in it also

I got mine out of the junkyard.... it was a GoodWrench replacement engine....N/A 109 SG1 ....engine was black... but with a blue 2bbl intake and quadrajet style (except 2bbl) carb on it. I assume it was in a regal or cutlass or something....

Casting numbers are 012 and 016 for the stage 1 blocks according to gnttype.org
They also have the power 6 logo cast into the block near the freeze plugs.... Make no mistake.... the SG1 block IS NOT a stage 1...... HTH

Sg1
I have a recently disassembled SG 1 engine from a 87 T Regal. The block is a standard bore and in excellent shape. I was planning on having it rebuilt next week, but I guess I could go a different route. If you're interested, make an offer and I'll let you know.
