Hi everyone. I have a 68 camaro with a 454 approximately 400 HP (came with car) unknown internals. Additionally the engine has significant oil consumption and many oil leaks. I found a great deal, $500 for a complete 6.2 L92 that has about 70k miles. The problem I need help with is: What motor mounts and oil pan would "guarantee" dropping in the engine with no conflicts?

Thanks for any and all help.
