Well took a little time today and dropped the engine in and bolted up the headers. Everything went fairly smooth. I need to take intake off and put the SVR module back on to see if it fits. Headers fit like a dream.
However the factory truck oil pan and pickup is a no go. The cross brace for the steering interferes with the pan. Could shift engine rearward slightly but I don’t think it’s enough before contacting firewall and definitely couldn’t run the SVR module in that case.
