I'm trying to determine if I can use the 454/502 EFI based K&N flame arrestor on my 350 MAG MPI (see pics below). This might sound a bit strange, but I think there is a good chance it might work. Can someone who has the 454/502 EFI package tell me what the hole spacing is on the throttle body (see pics below)? I know it sounds crazy but look.
Here's the kit I want to buy... I think. The hole locations look correct, but are they really? What do you guys think?
Here's a shot of the upper intake (see how it looks like the 454/502)

Here is the arrestor and throttle body.

Randy, They are the same, Both the 350Mag efi and 454/502Mag efi all use the same throttle body gasket #27-850396 and flame arrestor bracket #807654T
