So I'm going to put TrickFlow 58cc heads , rockers and rods, and LT headers on my 96 302. Should I notice a jump in power with just that or do I need to upgrade the cam? Not looking for high end mostly low-end power.... Also want it to sound a little meaner so will likely add a Borla or FM muffler.

 

You'll probably think the power is increased because you're spending so much time & money on it, but it will more likely DEcrease. The best mod is MAINTENANCE.
