It's been a long time coming but today I got the firebird on the "ground" with the belly plate bolted on so it's officially a rolling chassis and it's really low!!

JJ;

That's quite a belly plate! Any idea what it will weigh?

   I just bought a 4'X41/2' piece that was I believe 257#. Weight down low is good, Right?

This is roughly 5'x5'. It's 1/4". I don't have a weight but it ain't light. I guess around 250lbs according to internet.

The weight for steel plate is 10.2 pounds per square foot. When I'm trying to figure the weight of anything made from steel you can derive it from that number.  :-D :-D :-D

All those weights are confusing me. :-D
What isn't confusing is the quality of the build.
Way to go Joe. It looks right and will go just as good. :cheers: :cheers: :cheers: :cheers: :cheers: :cheers:

Missed one small detail Slim. I was thinking it!  :roll: :roll: :roll:

1/4" plate is what I was intending.  :-D :-D :-D

Old age strikes again! It seems to do that a little more often these days.  :? :? :?

I added some gussets to the cage yesterday and the body is going back on today. Building the nose structure this weekend. Still plenty of engine bay space for turbos and intercooler. It's the 5" exhaust all the way out the back that will be the challenge.

 That's my thoughts as well  :cheers:  

 I used the 10.2 lbs figure to calculate it. We can also pack the main frame rails with lead from the back side but I'm thinking this thing will be 5k lbs without ballast.

I've got steel at .283 pounds per cubic inch, lead at .409 pounds per cubic inch.

(Or, I wonder it those numbers were 1962 Chevy displacements?)

Those numbers do bring back some fond Chevy memories. When I run .283 through the calculator it comes out to 10.188 which is close enough to 10.2 for me.  :-D :-D :-D
