Re: Engine Blocks
Also, don't forget, the carb models have mechanical fuel pumps.
Your electric pumps would need to be removed (just use the mechanical pump from the replacement engine),
or replaced with units that put out ~6psi versus the 30(?)psi EFI units.
I don't think you can get a regulator to step the pressure down enough.
Or, are you swapping your EFI over?
If that's the case, you just need a $6.99 block-off plate to bolt to the timing cover in place of the mech. pump.
