Overload spring removal question

[68Timber]

I have the new wheels and tires on... It aint looking too good, it's going to have to come down more than 2/2. I was looking at the new rear springs, there's a spacer in there from God knows where. If I take the spacer and overload spring out I'll get another 2.25 inches. I'm worried about wheel hop if I do take the overload spring out. Has anyone removed it and ran a stout engine?

This is a pretty critical turning point, I want the stance right and I plan to put a fairly hot small block in - around 400 hp, give or take 20. It's gotta hook...

It looks like it needs a 4/3 drop to get it where I want it.

Thanks.
