Will my hei distributor that is in my early model 302 flat tap engine work in my new 5.0 roller engine that I am getting in this week? The hei doesn't have any brand name written anywhere on it so I don't know the brand name of it to look it up! But I've read somewhere that it needs a different size gear but not sure. Can anyone help with this I don't want to mess anything up when I install the engine
