Hello everyone, I purchase a chevy ls 5.3 motor .I want to add bolt on's with a daily driver in mind . I drive 110 miles a week. I want a cam that gives me a nice aggressive thumping sound but not sacrificing to much mpg??? . Beefing up the stock heads with better spring??? .


What would be a good cam and set of springs, headers ,timing chain, head gasket too choose from?????????????

One of my friends is selling me Lunati 55004LUN cam 221 int./221 exh. 0.558 int./0.558 exh. Can this cam be a good choice ???
