Hello all.. I know this has been covered before but with all the new technology coming out these days I just thought I would bring it up again. I am finally trying to get my engine back together and have acquired a set of Garrett GTX5518R 88mm turbos so my potential power making goals have jumped up a bit over the PT 106mm that I had laying around. My engine will be in the 470 to 490ci range depending on if I decide on going with a 3.75 or a 3.91 stroke crank with my 4.50 bore. My heads are a small but tall port design that did flow in the high 490cfm range. It was set up originally for a BBC style 6.385 rod using a 2.100 rod journal and a .990 piston pin. My question is about the rods.. Old school train of thought was an aluminum rod at the power level this thing should be at but more and more I am hearing steel rods being used like Oliver's. What are your guys thoughts on the subject. Also any thoughts on the new BoostLine Connecting Rods by Wiseco since the size I need is available in their new line? Any insight would be greatly appreciated!!!
