[6.0 1955]

I used the stock gauges in my 69 c10. Oil pressure is a manual gauge water temp is an electric. I took the oil sending unit from the back of the 5.3 broke the plastic top off . Cleaned out the sensor and drilled and tapped the metal section. Then I used the original water temp sending unit for a 69 by drilling out the water temp sensor hole and tapping as needed.
Using the ls1 intake will work just fine for a stock setup. The ls6 intake is good for around 15-20 hp over the ls1.
On the 700r4 you will have to use a spacer to allow the snout of the converter to align . You will also have to drill 3 new bolt holes for converter bolts. The only catch is the tv cable. Look at bowtieoverdrives.com. they sell a kit to use on the ls1 intake.
Ls motors are easy to work on so have fun.
