Rebuild 318 or go Crate

5.9 MAGNUMS SHOW UP FOR LIKE $500 with 100K miles. Should be less at a U-pull yard Hook it up with a Mega Squirt and you have a nice driver with your 300 hp with fuel injection for less than 2K total
Pretty much agree with MOPAR, just would keep the fuel injection. Need a high pressure pump at or in tank and upgrade fuel line.
