I haven't been on here in a while so I thought I should drop in. I had been thinking about swapping from '7165 6E to '7730 8D. I have 2 ECM's but both have 6 cylinder eproms. If I remember correctly I will have to have one for a V8 for spark control, is this correct? If so, I guess the next challenger will be finding one at a reasonable price.

As it turns out, now would be a good time to make the swap. The engine and transmission is out of the car due to a broken crankshaft.
