Thanks for all the replies! I was making an assumption based on my experiences with wet intakes (carbureted) where sharp bends were not condusive to making HP. Mainly because the fuel vapor would drop out of suspension with every sharp bend and restriction. I see it's not as important in a dry type manifold. Port matching and extrude honing the intake sounds like the best you can do with the existing manifold? Hone the UIM a lot larger then port match and blend the LIM may create a venturi effect that would help HP? Would a spacer/adapter behind the throttle body to help direct the airflow before it hits the 1st 90' bend be a waste of time? Sorry for all the questions but I don't want to do mods that gain little for the $$'s invested

On the exhaust side, I plan on doing the Y pipe mod, possibly headers too. Send it off to Swain and have it all ceramic coated or just get header wrap and cover the headers and Y pipe. Keeping the heat inside the exhaust definately helps scavenge the cylinders w/o having to resort to a longer duration cam to get the same results.I'm relating this to my old 351C where this helped out immensely! Not sure if this old school tech relates as much to the newer generation engines BUT I'm trying to learn
