I would throw in a "what to look for when buying" Not long but like some of the common problems(53 block,5th gear nut,loose front ends)

Lift pumps(fass,dtt assassin,raptor,airdog, others?)

Dont forget about the 3 key on trick for checking codes.

tranny upgrades(ats,bd tranny) Cutch upgrades(southbend,valair)

Lash adjustment is another good one

All out of ideas for now

 

what about maybe putting all the codes and what they are with the key trick that away its all in one spot. Find out how to do the key trick and also what the codes mean.... just a thought
