What does anyone recomend to install for the extra power from the engine so the frame stays solid i was wondering if the frame of a 48 year old car might need frame braces installed. Does anyone have any input on that subj

 

It will stiffen up the front chassis and help in the handling of the car .Along with frame connectors.

 

I'm Looking for something that will keep the frame from twisting as power is applied what is out there and what is recommended by anyone that has used them?

 

Subframe connectors,there are several styles available,I have bolt in connectors in my 2001 SS.
Some bolt in others weld in,some much sturdier than others,what you want depends on how much power you are planning to put to the test.
They start at less than $200.
