My 87 bronco was my first vehicle and After putting her up after highschool it has been setting for 10 years. I pulled it out from the cover and decided im going to restore it with my dad. Its has 302 EFI with over 300k on the engine with a c6 transmission I want to upgrade a little bit but i'm trying to find information on what would be better and most cost effective. Pulling it and have it ran through and put a bigger cam in it bored? Or buy a crate engine? The only issue is that i live in california which the smog laws are outrageous. Any advice would be extremely helpful.
