Big Block and Small Block chevy, How much do they weigh?
I have a 1970 Chevelle Malibu Cloned SS. It had a 400 small block with cast iron heads and aluminum intake, since then I have put in a 454 all cast iron with aluminum intake. I want to know the weight difference of a Fully Cast Iron Big Block vs. Small Block. I have tried to find info on the internet but I have not found much of anything. I put big block springs in the front and ever since it feels like I have a big boat ancor in the front of my car. I love the power but I find it is way too easy to bottom out. I am considering Aluminum Heads for the big block and would like to have the small block weight with the big block. Please only respond with weight if you know for sure. Here is what I found for cast iron BB and SB engines
Big Block 685lbs
Small Block 575lbs
How much do Big Block Aluminum Heads Weigh Loaded?
Any Help would be appreciated. Thanks
