Default Injectors and Compression
I have a 2005 Silverado with the all aluminum 5.3. What size are the fuel injectors and what is the cylinder compression? I have some *** whipping to do on a Mach One and he wont race my TA so the truck needs a 150 shot
Thanks
Mike

A guy on the truck side told me that the compression is 9.9:1 and the injectors are 26#
