I have a set of used JE pistons. Engine had only 5k miles on it. Absolutely nothing wrong with them. They come complete assembled with rods that have been reconditioned. They are assembled with ARP rod bolts. Crank is also avalaible if desired it is .010 over on main and rod journals. One main journal have a minor scratch and may need to be polished. Only reason I am selling them is because I am building a LS storker engine and no longer need the buick stuff. I am asking $650.00 for everything or $600.00 minus crankshaft. I am located in Washington MO. Thanks Bryan Here is TA Performace description. I bought them here and Have the printout of purchase. I will post tomorrow as well! I have included a picture provided By JE for reference. Our Spherical Dish piston is specifically made for Street/Strip 455 combinations. This unique piston is precisely made for us by the world leader in high performance piston manufacturing. The design of these pistons allows for a press or floating pin configuration on stock, forged or billet rods. They yield approximately 9.8:1 compression on most 455’s using stock `67-`74 (68-70 cc chambers)and approximately 10.2:1 compression with our Stage 1 and Stage 2 (64 cc chambers) series heads. These pistons on average weigh 856 grams with the wrist pin which is almost 200 gramsless than a stock piston with pin and 130 grams less than the production forged piston with pin. Many high end machining features that are commonly found in Pro Stock pistons areincorporated in the TA Spherical Dish piston. For example: The top ring land has multiple grooves machined into it which results in a Reduced Contact Area, thus reducing the drag on the piston. An Accumulator Groove is incorporated in the second land between the top and second rings, this feature displaces compression gasses that can cause ring flutter. Double Pin Oilers scavenge oil from the oil ring then utilizing internal passages to direct that oil into the wrist pin boss. Oil Return Holes in the oil ring groove return excess oil to the crankcase through the underside of the piston,this feature also aides in the cooling of the piston. Contoured Skirts remove unnecessary material to reduce weight. These pistons also have a specially Cam Ground Body, this procedure makes the piston slightly out of round. By doing so the loads of the piston are distributed more evenly which greatly reduces the stress on the cylinder sleeves and is attributed to reduced cylinder wall breakage. The most unique and exclusive feature of these pistons is the 20 cc Spherical Dish. The Spherical Dish, unlike a conventional stepped dish, directs the forces of the combustion gas's to the center of the piston. This in turn forces the piston down straighter plus the energy is concentrated down the centerline of the rod for a more efficient, horsepower improving cycle. Lastly, these pistons incorporate generous Valve Reliefs that will accommodate almost any valve lift. Like many of our products, we truly believe this is the best product for the money. There are other, less expensive pistons, but for the little bit you save you are losing out on some additional features that really DO make a difference in the power and durability that your combination is capable of. Many of these features are omitted or beyond the capabilities of other piston makers. Additionally, these features usually are expensive options, but we have worked diligently to make them TA standard features. Key Features: 20 cc Spherical Dish 1.975 Compression Height Reduced Contact Area Accumulator Groove Double Pin Oilers Oil Return Holes Contoured Skirts Cam Ground Body Valve Reliefs 856 Gram w/ Pin
It is a spherical dish and is very hard to see. Look at the outside edge and look in about an 1/8th of an inch that is where the dish begins. It is still considered a flat top piston by JE.
Block is up for sale too. The motor had roughly 5000 miles on it when I pulled it apart this fall. I had some hurt cam and main bearings. I was going to have the crank polished, and put bearings back in it and reassemble it. Then I decided to go another route and build a LS engine.:3gears: Block is a 1975 bored and honed .038" over for JE Pistons. Crank is in good shape but will need minor polishing. It is .010/.010 on main and rod journals Rods and JE Pistons with ARP bolts. Stock size lifter bores IF anyone would want the whole package, I will take $750.00 for it. Bryan
