Slant 6 Distributor
I think the ebay ECU is an okay unit, but a bit expensive. You don't need to have a high rev up to 7500 RPM. A 225 slant will never get to that RPM in daily or show car driving. I think you should save the money and install the HEI conversion. Get a distributor from Old Car Parts Northwest and collect all the other necessary parts from local junk yards and parts stores. I went the route you are thinking of going, and then I ripped it all back out and went with HEI. I am very pleased with the result.
