im in two minds atm in terms of whether or not i should start chasing some more power with my super6 such as intercoolers, diff gears, tunes etc. iv decided that if i am going to go ahead with it the engine needs 2 be in top condition. Im not sure where to take it just yet but what i was more concerned about was what the mechanic can really tell me bout the engines condition without ripping it all apart. would anyone be able to tell me what a mechanic would likely do and charge if i told them to give the engine an anal runover?
