Guest zfan Posted January 25, 2005 Share Posted January 25, 2005 As I had mentioned in previous postes my 383 had a failure. The crank cracked and I had several spun rod bearings as well. The block had a lot of trash in it. The motor had just 400 to 500 miles on it and I am wondering if I should reuse the block. The engine builder said it just needs a rehone and maybe a line hone or at worst a line bore. Like I have said the block is a hard to find 010/020 block and one of the real hard ones to find, usually bus motors etc. The block is and will be just 40 over but am I just being paranoid or should it be fine. I Also just purchased a Eagle 4340 forged steel crank for this build and scat 4340 rods to go with my old forged pistons. Because of the type of failure the shop that built my motor is doing the rebuild for free minus my buying the crank. The rods were my idea as my other rods have been abused plenty. The shop said they will give me another four bolt main block just not an 010 type block and if I would like I can keep my old block...my choice. What would you do and why.

Guest Magnum Rockwilder Posted January 25, 2005 Share Posted January 25, 2005 Keep it. It'll be fine. The machine shop has nothing to gain by misinforming you. Quote Link to comment Share on other sites More sharing options...
jt1 Posted January 25, 2005 Share Posted January 25, 2005 It will be fine. I'd rather have one of the older blocks at 40 than the newer ones at 30. If you have any doubts you can get a sonic check done to measure the thickness of the remaining cylinder walls. Since you broke stuff there is possibly a good bit of trash in the block. Make certain they pull all the oil passage plugs and clean the block completely. then a light hone and line hone/bore and you'll be good to go. john Quote Link to comment Share on other sites More sharing options...
Guest 77vegasz Posted January 26, 2005 Share Posted January 26, 2005 Always thouroughly wash your block even after the machine shop has cleaned it. You will be amazed at the amount of dirt still left in a block after hot tanking. Plus it will pick up grit from the air in the machine shop. Mr. Gasket sells motor brushes that will clean the cylinder bores and oil passages. Use very soapy water. Rinse and check every nook and cranny. There should be no dirt on a white towel as you check. Blow down with compresses air and spray with rust inhibitor. Bag the block, let sit for a day or two and you will be good to go on assembly.
