I was wondering what springs you guys are using to compensate for the additional weight of a 6.0 iron block and heads for your A body cars?
I have a 1969 Impala and I bottomed out more than a few times over small bumps eventually breaking the oil pan...
Any help would be great. Thanks

 

You have the relatively rare iron heads too? That is still not much heavier than a full iron small block, and still far lighter than a big block.
Get some big block springs.
BTW, the Impala is a B body. A bodies are Chevelle, Malibu, etc.

 

That explains alot... thank you

 

On the A bodies, you can get big vs small block springs, with or without AC even. I had to change out the big block, AC springs with small block, no AC springs to get a good ride going from a 455 to a 5.3.

 

If your pan bottom is below the crossmember, that's an opportunity area to improve.

 

As in, armor plate!

 

What oil pan is on the car ????? Put on a Holley 302-1 and problems gone.....

 

I use Global West small block springs with Ridetech single adjustable shocks. Very satisfied.

 

I had a truck pan on the 5.3 when I bottomed out. I have the china knock off of the 302 holley pan now on the 6.0 im throwing in
