440 EZ-325 CNC Questions
the reason I brought the 440-1 up was because a small amount of porting needed will closely equal the CNC maxed out EZ and you could use the extra money to buy some tti headers, intake, and rockers. The 440-1 will give you growth potential and you will have no trouble selling your headers.
Long story short if you are on a budget or don't have the block to support the 440-1 buy the EZ or pro comp with non MW window with sub 300cc port volume.
