I am working on a 84 f250 460. I am told that ther is a way to modify the stock ford holley to be an anti-backfire config. apparently you drill it somewhere and add a ball bearing that acts as a check valve to keep a backfire from blowing out the power valve. I am looking for info about this or someone who has done it. Does it work? Is it that simple?
