Phred, Good stuff.......I am planning on a total rebuild. I think that it woud be a waste to replace gaskets and not rebuild at the same time. I am giving the block and head to my neighbor to magna-flux and measure (make sure Im solid and plumb) I will have him surface the head and block at the same time (good idea) I would like a some vendor suggestions for pistons and rods. Also someone who does a good crank (Ive heard that the L28 crank it pretty damn good to begin with. As far as the oil pressure is concerned, you are the second person I have heard say go with the turbo pump...I will most likely . Phred: The solid copper .031 ( stock .047 compressed) head gasket has nothing to do with the valve clearance. It will move the valves a little closer to the piston, but stock cams have a lot of valve to piston clearance. Yes thats what I was asking...valve to piston clearance...thanks. I was planning on replacing the chain...thats a definate. I haven't looked at the cam gears yet...are you saying that they are adjustable straight from the factory. What do you mean by #2 hole??? Yes...Oregon is beautiful. My aunt and uncle owned a horse ranch right outside of downtown bend. I was out there for a few months five years ago...thats when I picked up the Z. Poor thing made it back from Bend Or to Westford MA in 22hrs 35 minutes. Its in suprisingly good shape. :classic:

Hey all....new here! Its time to rebuild the L28. I drove the car from Bend Oregon 5 years ago and it has been in storage since. My brothers bought me gaskets for christmas. I have a full set of engine gaskets plus a custom copper head gasket from a vendor out in cali. We are planning to pull the engine in two weeks and begin the brake down and inspection. I have low compression on #5-6...so expect the the h/g is blown....but I am also running very low oil pressure at idle. The car is a 77 280, is 10-15 psi normal for idle on that engine? Sounds really low to me. One final question. The copper head gasket is .031 in width. Does anyone think that I will create valve clearance probs by installing it. Will I have to step up the cam for higher cylinder compression (this is a plan that I have for the future anyway). Thanks all Dev
