Lee Marion posted that because he knows the person with the parts, you can get a hold of him at
W8CGQ@HOTMAIL.COM. The V6 engines are 351 and larger. so you can upgrade, the 351 is a straight drop in and provided you use the water pump housing from your 305 will have the exact same appearance as the 305. Also he has 401's which can also be a straight drop in with just one slight modification.
