I am looking to build a nice 383 for strip use only, but am still on a budget, first off I have read other posts and do not find answers I'm looking for. I would like to know if the 6" rod is better for my strip application, and I'm also looking to run an 11 to 1 Cr with a 64cc head. Will I be able to run this on a mix of 93 and 110 octane, or should I be better off with 10:7.1 cr due to fuel detonation issues, since I'm on a budget I don't need any catastrophic failure. The pistons either way will be forged. Thank you for all your help any info or opinions are appreciated.
