Check Out That Chassis

I know all the new rules (sfi) chassis-related
are supposed to make the cars safer, but they
also up the price of racing a lot.
I have a G body Malibu that
has an old style 2x3 grafted onto the stock frame
right in front of the middle of the doors and
a 12 point MS cage. Would it be possible to redo
the bottom 2x3 part in MS and graft basically
a chromoly cage similar to what you would see
on a prostocker onto the factory frame and have
it meet SFI good to 7.50?
Thanks,
John

John,
Thanks for reading our column and submitting a question.
You can definitely meet SFI 7.50 spec by grafting a chromoly
cage onto your factory frame. Depending on your configuration,
you'll want to refer to SFI Spec 25.4 or 25.5 which are listed
below.
Good luck!
Jim
