Your eng looks great. These are my 2" TTI's that I left in the nickle coating and they are fading a bit but we have the same headers on my sons Dart that have been on his car about 15 years and look about like mine so I hope this is the worst they get. I use the dual plane Indy intake that looks alot like the RPM but I believe it has bigger ports. Your combo should run strong. Is it an auto and if so what converter ? I use a Dynamic 9.5 street/strip converter and it works nice as it drives great on the street and works good at the track. What gear you running. Sorry about the questions but I like your combo and am just curious about it as it sounds like you plan to do the same as I do with mine. Thanks , Ron
