Catalytic converter questions
Wow no one posts in here very much, I hope this forum is still monitored.
What cats would you suggest for a 528" big block in a 6200 lb truck?
I have a non-catalyst 1986 f350 that I'm currently building an E85 big block for. I live in California so my concern is with the smogability of my combo. I understand that N0x emissions are raised significantly by higher compression, so if I increase N0x with 12.5:1 compression, can I run a couple cats to decrease N0x back to near stock "non-catalyst" numbers?
There needs to be more tech on this stuff for us California bbf'ers!
