Chevrolet Small Block V-8

Comments/Recommendations
This is a maximum performance carbureted street kit that will really light your fire! A zero-decked block with 4-bolt mains and a forged steel crankshaft will get you started. Add Lunati Street Race rods, P/N LHA1; Lunati flat top pistons, P/N 13H1J2S0 for standard bore engines and P/N 13H1J2S3 for +.030" over engines (to achieve 10:1 compression ratio) and Lunati roller rocker arms, P/N 84146 and you end up with a reliable combination of components that will perform. Top it all off with a set of Hooker or FlowTech headers and a 750 CFM Holley and you'll have what it takes. NOS nitrous, of course, is optional.
