Natural aspiration, or EFI???
Posted: August 28th, 2019, 11:29 am
If I build a 1991 - 1998 4.0 with a 1979 4.2 crankshaft, would EFI be the best route for more power, or nat. asp.?
Also, I'm in California, the dreaded emissions state, and, I've heard that I have a better chance of passing emissions testing with EFI.
Thank you in advance for your thoughts!
