You guessed it, 1950 s10 swap.

That's all great info. Thanks guys!!! I know the truck intake will provide more power but I ended up snagging an ls1 intake, rails and injectors. I'm not overly worried about horsepower and part of the reason I went with an ls is cause I love the look of the ls1 with the rail covers in a truck like this. I have an l98 350 supercharged that I decided not to use in lieu of the ls. I can already see the dollar signs add up but it will be exactly what I wanted. All rambling aside, I wanted to know what you did for your steam lines and did you use the truck throttle body? Now I've gotta keep my eyes out for a 4l60e trans. All of the newer silverados and sierras are stripped to the bones within minutes of hitting the yard and I'm too ignorant to know what other vehicles have the same trans (able to use with no mods). Any thoughts or ideas would be much appreciated!!! Thanks again and this thread is my motivation.
