Sorry guys I should have clarified what motor I have.. it is not a ZL1 motor... it is a 400 inch 23 degree Bowtie small block .9:5 to 1 pump gas motor . I am going to dress the motor just like my stock DZ 302 .
Rick , I would gladly give up the HP number for your Torque number

Regardless of performance.. nothing looks beter to me than an all aluminum BB .Your engine compartment is looking awesome !
