Hi, I have a question. I am building a 383 LT1, I know I will have clearance the block oil pan rail. The question I have is does any one have a template that has done this before? If not then I will have to assemble the block and start marking then disassemble it and recheck. Just trying to save some time.Thanks Ray

 

Every setup will need different clearancing depending on your block, crank, and connecting rod setup.
