1985 blazer project
 

I am just wondering if it is worth my time and money to buy headers, and intakefor my 2.8l v6 I have in my blazer? Or if I should drop a SB chevy motor in... I dont use it for hauling anything yet. I have another rig for that. I would use this vehicle for mudding and driving around town. It does just fine as it is but I like to tinker with motors and stuff. Any answers thanks guys.
