Hello Guys,

As I was test fitting the 427 BBC today, I come extremely close to the firewall on the drivers side.

I think I'll go ahead and "scallop" a small piece identified by the dotted marks.

Can you guy's recommend to move ahead with this, or will I encounter issues on the inside?

Thanks, Pat

As long as I have enough room to remove & replace the valve covers & distributor I am ok. Taking that section in a bit isn't going to cause any trouble.

The only problem would be moving it in to far could interfere with the full travel of the gas pedal.

Thanks Craig,

If I go in about 1/4" - 3/8" you think it would be ok?

Hi Pat,

Yeah, that's not going to cause any problems.

Are you going to use a cable pedal set up or the stock hard linkage ?

You get a lot more pedal adjustment with a cable set up like Lokar.

Either way you'll be ok.

Hey Craig,

Yes I will be using the Lokar cable setup.

I went ahead and "scalloped" it out today, and it turned out real good.

Thanks for the information.

Also, Bruces 57, thanks for the nice comments!

Pat

Pat,
I am NOT an engineer but I was a ship fitter.

My first thought when I saw your cut out dots
and other cuts made already,
was about the structural integrity of the firewall.
Where your marks are, is on what appears to be
a strengthening column.
You might want to get an opinion more qualified than mine about re-enforcing that area.
Good luck.

Thanks for the information Bob!

I took out a very small portion of the firewall. It really is a small segment, so I don't think I need to worry about it too much.

Thanks again,

Pat
