Every block is machined and assembled at the Texas Speed engine facility. This listing covers all 3.622\" stroke combinations, from a 3.903\" bore 347 up to a 4.185\" bore 398, and Texas Speed recommends the 3.622\" and 4.00\" stroke versions for power-adder builds.\u003c\/p\u003e\u003cp\u003eThe buyer configures the engine at ordering with a crankshaft, 6.125\" connecting rods, Wiseco or CP 2618 forged pistons with lowered ring lands for nitrous or boost, PRC cylinder heads, head bolts or studs, head gaskets, main studs, oil pump, rocker arms, timing set, balancer bolt and reluctor wheel. Oil and coolant plugs come installed. Texas Speed offers a 1\/2\" head stud upgrade with the required machine work for heavy nitrous or boost, and an optional LS2 conversion package for installing the engine in an LS1 vehicle. Twelve quarts of break-in oil are included, and the engine ships by truck freight with the final freight cost quoted after the order.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDisplacement: 347 to 398 cubic inches depending on bore (3.622\" stroke)\u003c\/li\u003e\n\u003cli\u003eBore and stroke combinations per Texas Speed: 3.903\" = 347, 4.005\" = 365, 4.01\" = 366, 4.03\" = 370, 4.07\" = 377, 4.100\" = 382, 4.125\" = 387, 4.155\" = 393, 4.185\" = 398 cubic inches\u003c\/li\u003e\n\u003cli\u003eBlock: New Gen IV aluminum LS block (GM Gen IV 5.3L block selected at ordering, or customer supplied)\u003c\/li\u003e\n\u003cli\u003eSleeves: Power Bore or Darton dry sleeves, selected at ordering;
