This is a SB2.2 GM Performance Racing Block fresh from a top NASCAR Race Team. It has 2,311 miles use. This one has Nickaloy Sleeves, a option supplied by GM for high-tech engines. (Small Block/second generation) This engine was produced from 1996 to the present for racing applications only. The cylinder heads were redesigned and the lifter bores were offset. The valve sequence for each head was changed from the traditional E-I-I-E-E-I-I-E to a new I-E-I-E-E-I-E-I and because of this the camshaft was redesigned.

SB2 -- Foundation for Horsepower

The SB2 -- short for Small Block, Second Generation -- is the first engine designed by General Motors specifically for NASCAR racing. It simplifies preparation for racing teams, and reduces the overall cost of building and maintaining an engine. The SB2 was presented to NASCAR officials in late 1995, and won approval for Winston Cup competition before the 1998 racing season. It is the basic engine behind some of NASCAR's legendary drivers, including Jeff Gordon and the late Dale Earnhardt, a member of the RCR team for 20 years.

The original small-block V8 was introduced in 1955. Over the years, modifications for racing were made to the original block design to increase durability and to add features needed to work with each new cylinder head design. Since the original design dated back nearly 50 years, there was no 3D digital model of the block, only 2D prints.

For Winston Cup and Busch Series racing teams, the SB2 is just the starting point for building a competitive racing engine. NASCAR teams spend hundreds of thousands of dollars and tap into a treasure-trove of skill and imagination to reach peak performance of 800 horsepower for Winston Cup and 700 horsepower for Busch engines. In comparison, the original GM small-block engine produced 162 horsepower. The carburetors in SB2 engines deliver more than 800 cfm of air/fuel mixture and the engines get about four miles to the gallon.
