I'm building a 396" stroker

Hmmm, looks like I will be half and half then on the race fuel huh? You all are saying that if I want to run this particular cam then I will have to run race fuel in the car for it to run right and not detonate. Not because its the wrong size period right? Is this a good cam for all out performance from this combo? I have a mopar 296 duration .557 lift does this sound better? let me know, when I say better its only so I could run pump gas, but I think I'm looking for more performance than cheap fuel, lol.
