I have an 1980 cobra and I am changing from the draw through turbo 4 to an 87 roller 302. my question is what distributor do I need to use in this block since I am going to use a carb set up? and what if any cam would work ? I'm open to aftermarket ignitions if necessary. and would like to spend around 600.00 since the rest of the budget will be spent on putting the engine back together. any help would be appreciated thanks.
