New 5.3L Question
Do the 5.3 engines in the 07 models have cathedral port heads? Do the 07's have the 58x reluctor wheel? Do the 08 5.3's have cathedral port heads? I wasnt sure with the new LS3 architecture what exactly has changed.
Thanks,
Daniel

The L92/LS3 heads have the bigger valves and square ports and GM would have to put smaller valves to get them to work.
