    add to piston question

     



    I found a kb that will get us there, question is at 8.3 -1, isn't that considered down a little on compression for a 402? Thanks.

    yeah thats stock compression
    If your running aluminum heads, you can go at least 10-5-1 to 11.0-1 compression with a decent solid you wont detonate on premium unleaded. You need to have some compression to make any decent power.
