If I decide to go with a 454, and swap it with current 283, I understand I need to change motor mounts, and crossmember mounts, do I need to change front springs too?
Car currently sits too low for my taste, and will be looking for ideas how to lift it all 4 corners....

The added weight will drop the front an extra 1/2-1” depending on springs. If the car is too low for you already, I recommend UMI 1” drop springs. Or standard height springs depending on what you’re going for. I believe they have picture examples of each on their site of I remember correctly. You can always cut front springs to bring the height down. Conversely you would need spacers to go the other way. Just something to think about.

Well I certainly don't want a 1" drop kit...lol I'm wanting to raise the car front and rear...
I would think I'd need bigger/longer springs?
I'll check their site....thanks

A 1” drop spring will not drop it more than it is now. It lowers it 1” from “stock”. You likely have old and worn saggy springs, or someone chopped yours down.

Taller springs are exactly how you would raise the ride height.

I’d recommend new springs. Not spacers.

But first, so I/we can make a better recommendation, what is the status of your suspension? New? Old? Stock rebuild? Performance? Original bushings? What springs? What shocks? As you can see we can go down the rabbit hole pretty quickly.

Looks like a BBC spring will fix the front for you.

Yeah, but the $64,000 Question is : "Are the bushings, ball joints, column connector, steering gearbox, tie rod ends, etc parts also just as tired or worn out" ??

Springs may not be the end of what you will need.

Or has all that already been rebuilt, and just the old springs got re-used?

If everything is original like you say, you need to go through the suspension and make sure it’s safe. If it were me, at minimum I would replace all bushings, ball joints, springs and shocks. Then get an alignment.

But to answer your original question, buy some stock replacement springs if your car is too low. Or stock height or 1” drop from someone like UMI. You’ll probably want new shocks too.

Since you asked where to buy, I buy most of my parts from summit racing. Fast shipping. Great customer service. Outstanding return policy.

I am a believer in if it isn't broke do not replace it.
I have the original riveted in ball joints in my 57 chevy and original tie rods.
I did replace some A arm bushings.

I feel those old original ball joints are probably way better than what you will end up with at most parts stores.
They are not busted and I will not replace them until they do get worn.
I drive my stuff often and I race it and also go off road often as it is my hunting /fishing vehicle.

I like my stuff to sit high as my hunting spots require it.
My front springs were very soft and sagging in the 57 and in my 78 Nova.
I took so much weight out of both of those cars that the springs ended up pushing the car up against the snubbers.


Not that you will be removing weight.
Just mentioning that as one car may be an AC car with the old A6 compressor and all the heavy steel/iron left under the hood.
Another car may be without air and have aluminum heads/intake and headers.
As we know that will make one sit much higher.

Pay attention when buying new springs, I bought new HD front & rear springs and my Chevelle rides like a nice new 1/2 ton truck lol, front are for an iron headed BB with ac, rear are HD for luggage etc.
