Cool.. I have the Holley pan and just had it sitting in there, much the same as you did. I slid everything forward as far as I could and it looked tight. But I did have some column interference, casting me off at a slight angle. So I suppose with everything square, it'll probably go more. My biggest concern as for sliding forward any farther will be the headers. That's one of the reasons I opted for the shorties.. hoping they are a little more forgiving. We'll know this weekend!
This I agree with totally. I know everybody loves the Holley stuff but if you don't really need all of that.. skip it. I don't mind wiring but why add more pain. On my current swap, I ended up with the stock harness and ecu, so I'll be going through Sublime and saving a few bucks on the Quick Run and a flash and save a few bucks. My last swap, I used a Mopar Crate Harness and it was great except I had to reroute the starter wiring to the drivers side and it sure would be nice if you had just a little more length for the ecu.
