Are heavy coil springs necessary?
I'm planning on putting a 455 into my 70 Cutlass, currently a small block car. I plan on aluminum heads and intake, and was curious if I would still require the heavier duty big block springs in the front. Not sure what the weight difference is between stock and aftermarket. Might be a dumb question, just trying to save a few bucks! Thanks

The difference between a stock 350 and a stock 455 is about 50 lbs. I've done this swap several times and never changed the springs - in fact, I've had to cut the springs to get the nose down to where I wanted it.
