a question on rods

ok folks my intended build is a 460 bored .030 crank ground down to 2.20 and offset .030 to make 470cid and use do i dare say aluminum chevy rods. my question is now how long of a rod can i use and still keep ththis beast from eating itself from the inside out

lmao yea there's a reason behind that which is this is going in my pulling truck which the class i pull in has a cid limit of 472 so i gotta whatch building too big
