Hello Everyone, I know that the words 'gas milage' & 'big block' shouldn't go in the same sentence b-u-t I was wondering if anyone had any idea how much fuel injection on a 502 crate motor would help the gas milage??? I'm referring to the Ram Jet 502 {#12499121} virses part #12496962 which is the same motor but has an 850 Holley on an aluminum dual plane virses Port Fuel Injection...... Thank You! Billl
