Barely run, it won't be driveable at all.

 

It might run decent if you leave the stock injectors in there. Just don't go very high rpm. And the transitional stuff, acceleration enrichment, will be weak. If this thing makes close to 400 HP you'd be better off going to speed density, like a 730. It's been covered before on this board so a search will reveal all.

 

You'll run pig rich until you re-program the injector constant. Then when you 383 maxes the MAF it will run lean - possibly too lean.

You need a chip.
