I have not noticed it elsewhere in this thread, forgive me if it already is, but the oil pump drive shaft should be upgraded. There is a PLASTIC piece on it that can break. I got an all metal one from a machine shop when I had my dizzy out. Just want to contribute what I can.
I also use a 180 tstat, altered settings on stock computer to turn on electric pusher fan sooner, and rip out the wheel well covers if you have them. Let's heat out better. A body lift would help too, I plan on it someday. And I have a. 4 core aluminum radiator from ebay.
Altered power enrichment where it kicks in when needed by throttle position, that alone helped pull hills better.
I have 3.73 gears, and installed 225/75-16 10 plus, it's like changing to 4.10s, although it looks a lot better with 265's, it tows a ton better.
I also got a set of RV style high heat plug wires with porcelain boots.
Called Delta about a regrind cam, planning that soon.
Desktop Dyno, for what it's worth, Playing around with numbers, it easy to get over a 50flb increase and 70 hp over the whole rpm range.
I have a 0411 and the spreadsheet from lextech, ordered one with a vin from an express van, just haven't pulled the trigger on repining the harness yet, with HP and a custom os 0411, you can real time tune your VE, and Spark.
Hope that helps someone, sorry for long first post.
