I would say maybe about the same as a 389-400 depending on how cheap you can buy a 301 engine and a 3.75 crank.The spacer was about $80.The intake is the expensive part.Contact Dave if he would do another and how much.If you have time and are a good alu welder you can do one yourself.IMO the best way is to buy the complete 301 engine as you will get the intake to cut the water X over off,the valley pan and the dipstick and tube you would have to go out and buy anyway.I bought the block alone and bought a 326 engine for parts but it did not supply some needed parts.This engine because of not knowing ended up stupid expensive.Tom
