Spring/ride height, 454 vs. 350 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an '85 K20 Suburban (350) that has front springs that were bought new 10-15 years ago, but were only driven less than 15k miles.
Measuring against my '91 V3500 Crew (454), the Suburban is just shy of 2" taller to the edge of the fender well than the Crew.
How much of this is the 454 vs. the 350?
The spring packs are the same amount of leafs (3?) and both have negative arch.

I would like to put the Suburban springs on the Crew to help level it out a little bit, but if it is all in the weight of the engine, might be better to just buy some lift springs?
