Front coil spring question
I recently put an all iron 454 with an 8-71 supercharger in my 69 and the front end is sitting low because of the weight. An all iron big block is heavy as it is and now it's even heavier with the blower on it. I weighed the complete blower assembly with carbs before I put it on the engine, it weighs a whopping 160 pounds. The car already has big block with A/C front coils in it and they're not enough, the front end is sitting very low. It needs much stronger front coils than big block with A/C coils. F41 and gymkhana coils won't work either, those coils lower the front end which isn't what I want, I need to raise the front end at least 2 inches or more. Are there stronger coils than big block with A/C coils available anywhere? Are there coils from another car or truck that can be used? Any help is appreciated.

I'm trying not to go broke doing this, lol. Coil overs ain't cheap at all. I really don't want to spend a grand or more fixing what should be an easy and relatively low cost issue to fix. I wonder if a 2 inch thick spacer under (or on top of) the spring would work? Do they make coil spring spacers for a Vette?

Try Hyperco. https://www.hypercoils.com/spring-rate-calculator/ Or maybe Eibach or Penske. A custom wound spring may be your only choice.

I've tried two different sets of springs in it already, a set of factory original big block with air conditioning springs and a brand new pair of big block with air conditioning springs from zip Corvette. Neither of them are strong enough, the front end sits way too low with either of them. An all iron big block with an extra 160 pounds of supercharger sitting on top of it really lowered the front of the car, I need to get it back up to a reasonable ride height. Before anybody mentions it, no, I'm not going to spend a couple of grand on a set of aluminum heads for it to take some of the weight off of the front of the car, it wouldn't remove enough weight to raise the car up to where I need it to be.
