The Buick we currently race in Drag Radial, had a 10 bolt under it when we bought it. The car had run 5.50s with small blocks when we bought it and our big block made it a 5.20 car right off the bat. We ran the 10 bolt until we broke it (which wasn't long). The point was, the car "evolved" from a streeter to a low 5 sec car and the 10 bolt was "good enough" to a point.......then it wasn't.........so in Dom's case, moving from an 8.75 TO an 8.8 under his car........well he may as well light that money on fire, because it will accomplish the same thing.

Just curious Monte, what rear is in that Buick?
Chromoly 9" sheetmetal Ford housing, with 40 spline gun drilled axles, alum Mark Williams center, with a 3.70 Pro gear and a billet 1350 yoke with a solid joint............expensive? yeah I guess, but high power, hard hooking radial cars will break EVERYTHING. Radial cars are harder on drive line parts by FAR than slick tire cars. That said, we have NEVER broken a single part in the rear...........Several radial guys I know this year were twisting and breaking 40 spline axles. That's how hard these cars can be on parts.

If thats the case, then move up to a Dana 70, 10.5" ring gear, 35 spline axles, 3.5 tubes with .5 wall thickness, looks like a 60 but on steroids inside! 1401 ujoints and a bunch of ratio's up to 7.17 to 1 Tim
Oh I love getting on here. Twisting 40 spline axles and should go back to 35 spline and add 150 lbs in the process. That is exactly what they should do. I think you should call all the big chassis shops and get them all on board with the dana 70 movement also. You better buy up all the parts they are going to be flying off the shelf.
