    Re: Best head & compression ratio on a 331 and 408w turbo motor

    I would try taking a look around the "builds" forum. Lots of answers in there. If it were me, on a 331 i would use some AFR 185's. On a 408, i would go with AFR 225's. For a pump gas, street car application, i would get the compression somewhere between 8.5:1 and 9:1. Also, the SEARCH function is a great tool on this site.

    Good luck on your 1000 horsepowers. That is alot of horsepowers.

    450 can scare you if your green.

    For a street motor I agree with the above at around 9 to 1
