Getting ready to order parts and am looking at using the TA_1630B rods with AutoTec Forged 350 Buick pistons (If my block doesn't need to be bored over .030"). I noticed that TA says these rods have a wrist pin bushing.... does that mean the pistons use a retainer ring to keep the wrist pin in the piston?
Yes the B rods should use a retainer ring. The A rod is press pin. Also use a .927 pin(small Chevy) so you would need to specify when ordering piston. And your better off with some kind of overbore to true cylinder for best ring seal. 350 can handle pretty large overbore after sonic check. Autotec has custom head gasket for larger overbore.
Good deal, I figured the wristpin must of used a retainer with the smaller pins. The reason I specified .030".... that is the largest size the autotech specifies for these forged pistons: https://www.buyracingparts.com/pist...totec-forged-350-buick-dished-piston-kit.html Thanks for the info!!!
You have to get new pistons anyway, autotec is the same price for any size, might as well spend the extra $200 in machining and have the block trued up.
Of course! The block is currently at standard bore, and it is in the machine shop now to be "trued up".... I just didn't know how large the bore would be. I also didn't know the Autotec pistons were available over .030".
I called Auto-Tec direct and they made mine in .040 over with thin rings and 11 to 1 They'll make to any spec you need.
