    When I purchased my 1967 Buick Skylark. the original diff with 2.78 gears had been upgraded to a posi trac with 3.23 gears. I want to make the move to 3.73 as I am running a 200 r4 and at highway speeds it a tad sluggish and I am looking forward to a faster start off the line. The engine is a buick 340 with mild mods so maybe 325 hp. So my question is where is the break on the carrier? I could have sworn it was maxed out at 3.23 and that I needed a new carrier, but my gear supplier says the break is at 3.08 and that my current carrier is good to take 3.73 gears. He also questioned splines, 27 or 30...and that I need to remove the cover to check. yuck...My Garage is is not heated and "Baby it's cold outside".
