What suspension for heavier V8 swap?

[bmk]

Hello all, Im in the process of an LSx v8 swap in my 86es. Im running a 5.3L iron block, in the end im guessing it will be around 100lbs heavier in the front. What suspension will work good for highspeed/spirited mountain driving. I dont have the cash for a full coilover set up, but maybe looking at something like the GC with custom rates but not really sure what rates I would need. I was thinking about Koni SA W/ H&R race how will this work?

Any input or advice is appreciated. I am a compete suspension noob

Coilovers aren't as expensive as people think they are.

I'd run something like 450 to 500 front and 500-600 rear.

Otherwise there's definitely nothing wrong with something like H&R Race or IE3 springs.
