On my 69 Camaro 350, I am considering converting to HEI. This car is just going to be a cruiser. I don't need a high dollar drag racing setup or anything like that. My 55 Chevy has and HEI that looks like it came out of a stock GM car. My question is this, I see HEI distributors on Ebay complete for as little as $65, are they junk or should I buy a simple to install distributor at Oreilly or Autozone that will do what I need? Also, from the posts I have read, it sounds like all I need to do is pull the current distributor and coil, wire the one wire from the HEI to the resistor wire close to the plug on the firewall. Is that it except for timing and so on???
