im a little car dumb so bare with me.
if i cam the balt will it need a tune?

 

yes
you will

 

god, these arent n/a v8's were talking about here

 

yes, but be very aware that not many people have had successful cam installs. lifters collapse, valvesprings break, lash adjusters need constant adjustment. i honestly wouldnt do it, not until a better solution is found
