Turtle, that was a 2018 Calif smog test
Second set of CATs and with the OEM CATs had an even lower levels. These are 'rebuilt' (but on the Calif approved list) and will go OEM on the 3rd set, which will be several hundred bucks more
Since am still noodling the rebuild of my Suburban, this is an important area of consideration.
Giving up on any aftermarket direct injection heads and will go OEM port injection. Though matched and tuned spider injectors will have to do. Maybe higher rate injectors, if they have any
The biggest concern right now is upping the static compression to 9.2-9.4, from OEM static of 8.5. Am okay with having to run +90 octane, but it has to pass Calif SMOG. To date, can NOT find a builder who will give a good answer on the amount of overlap for the cam and still pass SMOG. So presently looking at a 280 cam as the max
Just curious how the diesel's of today are running and of course, understand that my 24 year old big block will never be close...just good enough for me. Going 5.38's for both diff's will help and can't find 5.38's for the front diff...yet
