I don't believe the intakes interchange.

You will need spacers for the intake.  are you talking about the mechanicals working or the wiring?

I was curious if the stock 454 tbi chip would compensate for smaller displacement and the extra runner length from the spacer plates, without having to adjust nozzle pressure/custom efi chip etc. The only wiring issue I can think of is just making sure I have the right distributor the rest should be straight forward? Thanks for the input!

Should be ok, but you may have to get a chip burned for it.  I think they put TBI on the latter 366's.
