Well heres the deal. I dont know much about building engines so i need some help. I have the books but they are only so much help. I bought a bunch of parts from a guy a while back (he was hard up for money) that included a cam., all bearings freeze plugs, rings, oil pump, and lifters.. and a timing chain set. I paid $100 for it and I would like to use these parts on an 82 corvette motor I have been dragging around with me for years. My first ques. is about the cam. lift .305 valve lift .458 lobe ctrs. 105-115 adv dur 284 .050 dur 218 Its a Crane Blue racer. Now what the heck does all that mean!? I am wondering if this thing is crap or usable. Sec. ques. is would it be horrible to just throw some new stuff in this well maintained motor without doing any machine work? What this comes down to is me being board and broke but I have all this cool stuff to blow up.
