We blasted my 57 hardtop. There are issues we are working on.

After we pulled out the engine, I noticed that the humped area of the firewall was beat to a pulp with a hammer. We think someone did it to make room for a big block as the car appeared to be a drag car at one time. The rest of the firewall is in very good shape. I hate getting rid of the original firewall to fix the area. It is also pricey. Does anyone have an old firewall with a solid hump they are willing to cut out and sell?

Replacement ?

I'd at least trial fit whatever engine I was going to use with all its accessories and what is actually visible before replacing it . Major work, You might get away with a little messaging at bondo. Many cars with tall cover small blocks would love the extra room you are describing. I also had my cor media blasted about 3 weeks ago and I suggest blowing and flush (with warte hose) the living daylight out of the vent sytem you'll be suprized how much you get out.

A photo of what you describe might make it easier to advise.

Is it really too far to hammer and dolly out? Replacing it would probably be a good bit more work unless it has really been stretched outta shape.

My '56 firewall was the same way. Sledge hammered way to bad to be repaired so I welded a new hump area in from a donor firewwall. It was not that difficult and saved alot of hours of trying to repair damaged one. At the same time I filled and smoothed the remainder of the fireall. :anim_25:

I can take a picture Tuesday. I pretty much need the areas where there are it indents. Starting next to the opening for the heater, lower part at the crease. The right side to where it start flat again before you get to hole for steering. Does that give you an idea?

If your running a small block then its a concern if your planning on running a big block then its a mute point. Because if you want to do it right you'll need to buy one of those firewall section specifically made for a big block but if small block is your choice of power plant there are plenty of vendors out there offering replacement firewalls they may be a pit pricy for your repair. I would first try reversing the process with a sledge hammer, from the inside of course maybe I think you may be surprised at how easy you'll find it to get pretty close to the original shape.
