does anybody know of a good reference site for the how to do's. I've always replaced things on all my vechiles (truck,car and motorcyle) like alternators, brakes, tunes ups etc. It'd just be nice to have something to refer to in case I crap on myself lol

Don't put a 3" exhaust on that motor.. it won't help milage. A longtube header or tri-Y header is a good upgrade, but stick to a max 2.5" exhaust or even 2.25", the I6 does not move a lot of air and a big exhaust will kill low rpm power.

Hey guys, just wanted to throw a update.

After checking tire pressure,putting new spark plug wires on,taking off canopy,changing oil +filter, and most importantly driving like an old grandpa. Over the weekend I took a trip (140 mi round trip, freeway doing no more than 65 mph) and I was able to get freakin almost 19 mpg! I'm pretty stoked. What a difference going from 14mpg to almost 19!

Thank you guys so much,
-AJ

I agree that the 4.9 300 doesn't need a 3 inch exhaust. A sinle 2.5 is sufficient for it.

Converting over to synthetic oils will help with mileage. It sure made my heavy-*** F350 move easier when I did it.
