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.
