Anyone install the ARP main stud kit and have the oil pan not fit over them? I have a 67 400 block but it looks like the bolt holes for the #1 cap aren't drilled and tapped as deep as the rest and is not allowing my pan to set flat without sliding forward. I am looking to massage the pan with a hammer but I am not sure I can get it out enough to correct my problem. I was wondering if anyone else had this issue and how did you fix it? Since the tolerances and bore have been done for the studs I don't think I have the option of installing a set of ARP bolts in front cap. Any ideas? Clyde
Hurm, my arp studs did stick up higher on the 1 and 5 cap... but I didnt have a clearance issue with the pan. Are you running a rear or center sump pan? Might want to try a 455 pan if possible or a thicker gasket???
Clyde, how much higher are the studs pushing the pan up? Dimpling may work for you if it is not excessive. I ran into this many years ago on a 455 and double gasketed the oil pan. Do it very carefully and seal it properly and there should be no leaks. Good luck! George
Thanks Thanks guys. I called TA and I guess this is the norm for some of the earlier engines. Their stud kit is made custom with the front two studs made short and with 12 pt nuts. So I am taking to the machine shop to take 3/8" off. I think this will be enough as the pan is only 1/4" high. Even with this TA said I might have to dimple the pan. Next set will be from TA Clyde
I had the same thing happen with the front two main cap studs in my 462". Mock them up, measure, remove, hacksaw them to length, clean up on belt sander, clean and install. In my case, no pan dimpling required.
Mock I was mocking the whole thing up to test bearing clearances and I threw the pan on to cover for the night when I noticed the issue. Glad I didn't get farther than the test run.
