Is this system compatible with a ford 302 engine? What other changes will be required?

Asked by: chico
Yes, as long as you have a square bore intake flange for this to bolt up to- it would fit perfectly fine.

In the description states compatible with 700R4. How does the Sniper EFI system communicate with a 700R4 transmission? What additional harnesses of linkages are needed?

Asked by: Al25
The 700r4 does not require a transmission computer. It does require a tv cable. Page 7 in the manual illustrates where it will connect just like it would to a carburetor
