can a Stock 502 Mag EFI system work "with no fuel pressure changes" On 502 HO Crate engine. using stock exhaust.

no one knows ?

Rich as these 502's run I guessing no. but was hoping someone has done this.

what are the horsepower figures? I mean it will run it but if you have a lot more horsepower with your crate engines I will need to determine the BSFC to know if an EFI upgrade is needed. For the most part though yes it should work fine.

I believe that is just a stock 502 like the 502 Mag. The cam specs are a little different but I would think it should work just fine.
