Replacement coil springs on C20 Burb w/BBC

I have a C20 Burb that came from the factory with a 350/350. The previous owner put in a 454 with iron heads, and I assume did nothing to the suspension......

I searched the forums and didn't really come up with much....mostly about lowering....not what I am after.

The front is very heavy now, and assuming that the springs are still 3/4 ton SBC units, and 40 years old.....

Do you guys have any recommendations on which coils to put up front? (is there something from another vehicle, maybe one that is a 3/4 ton that came with a BB, or from a 1 ton?)

I think the rears are OK as not much extra weight there, but maybe they should all be replaced if changing the spring rates on the front?

Thanks,
Tim

Great! Thanks.....almost didn't find the stock height ones, but a little drop down drilling found them!

Thanks again.
