Formula 311 Engine Swap

Hi Guys,
Had my 1990 Formula 311 over a year now and absolutely love it!!! Unfortunately, it came with the 330's. So I am buying a set of 502 MPI's to wake it up a bit.

I'm assuming they should pretty much drop right in. I'm sure some of you have made this swap. Are there any issues here? I think I read somewhere that there might be an issue with the silent thunder, but I don't se how that could be.

Any thoughts would be greatly appreciated.

I think you are in the wrong section.
Did this exact update on my 89, everything bolted up for me.
I swapped mine to a carb setup.

Formula section will have more info.
