I was having issues with power and overheating while towing my Patriot trailer, so working with my shop, decided to put in the Edelbrock head, new cam, headers and new radiator. While we were in there, we port matched and polished, and did some clean up. Haven't hooked up the trailer yet, but very happy with the results after tuning. Just wish I had dyno'ed before the mods were started to see the full gain.
