Hey guys so I would like to get a few things but I need help figuring out what is good and where to find them. If you can help me with any of these, even just your $.02 is appreciated!!! 1. Cyberdyne O2 Sensor kit with gauge. To check the richness of the engine... Possibly any other kits that are good for that? I can't find the kit on Summit... 2. Thermocoupler? (I think that is what it is called)- a sensor that is on new cars, goes on the side(or inside) of radiator instead of going into the block. It controls turning on the electric fan.... long story short, the one in the block failed to turn on the fan when driving one day. I do not want that to happen again. 3. I will be running a Champion Aluminum Rad that is a 3 row, plus aluminum water pump and manifold... now I have heard I should run something special in the coolant that new cars with alumium blocks have... now what is that called and how much should I be mixing in with the distilled water and antifreeze? 4. Fuel Regulator- around 6psi I should be running. I'm currently running a Holley DP 650 but will be jetting it up hopefully to a 750 range. 5. Oil Dipstick- for 86-up one piece rear main seal with passenger side dip stick, I have heard bad things of the Lokar ones but I have been thinking this Milodon stick: https://www.summitracing.com/parts/mil-22005 has anyone tried this or have any other suggestions.... how are the cheaper brands in the price range of $30 looking similar to this one? Any help is great! Thank you.
