I am building a 327 using a new 350 block and a forged eagle crank with a 327 stroke. First the counter weights hit the piston pin bosses, had to grind the crank, had to buy120.00 of mallory metal to ballance the crank. Now I have .009 side clearence on one set of rods, .006 on the second, less than .003 on the other 2. I have the bearings that are clearenced for large radius cranks and the bearings are not hitting. The pair of rods that have .007 clearence can have an .008 feller gage between the crank and the rod on the outside and a .003 feller gage between the rods, I can not put the .008 gage between the two rods with nothing between the rod and crank so I think the radius of the crank is hitting the rods. Has anyone else had this problem. I talked to eagel but they are not much help, after about 5 min I asked if the paint wore off the yardstick they used in qC probably sould not have said that but!
What pistons? What rod length? Something's not right....no way you should need mallory to balance a short stroke 327 crank. Sounds like your pistons and rods are unusually heavy or you have a diffrent crank than you expected. I cant imagine why you would have clearance problems on a short through crank. Something is off. I recently got an Eagle crank and thought it was great. I had no trouble balancing an IB chevy 400 crank with 567 gram pistons and LT1 rods. No mallory needed.
