Sticky thread with equivalent automotive parts that fit our engines?

On rock auto when I look for the 99 silverado it comes up with a 5.3 V8 but if I look up the C1500 pickup they have the 5.7 V8

1999 is a mid-year cycle change. Use 1998 Silverado for Vortec 5700 parts. The C1500 is the same also. 1998.5 the switched form 5.0/5.7 engine to 5.3 motors and later 6.0.

5.0/5.7 is your block.......the 5.3 is LS based and won't work.
