anyone ever install big block springs on a small block car?...to get a higher ride height.

 

What is your reasoning for wanting to put in b.b. springs?
1) The nose of the car is going to be riding a bit higher, looking a little like a "gasser" drag car.
2) You are going to have a much stiffer ride up front.
3) You're going to have less body weight on the front tires due to weight transfer shifting to the back, making the car more snaky around turns.
Unless maybe all of those things are your goal?

 

You can also expect irregular outer tire wear. wy yu wanna doo datt? ........wy?

 

Yeah, that too. And I also forgot to mention that the ride will be so bouncy, your fillings will jar loose. And you'll also have to pull over every five minutes for a pee-stop!

 

pee-stop!? every five minutes!?Just wear those extra absorbent underpants that truckers use.
problem fixed!
Proceed with the installation of those big block springs........
