440 duster. Need engine build advice

nice man you are doing the right thing. it will be an engine you can depend on and enjoy for a long time... also if you ever sell it let me know lol. it will be worth more than 800 bucks if it's done right. it sounds like with the pistons and rods you have you will be fine.

p.s. make sure it's a new oil pump. that's your $40 insurance.
