Ok so I have a 5.0L 302W with the dual throttle body assembly. Is it difficult to convert the top end to a mustang manifold and the single inlet throttle body. I just bought new high flow injectors, will they work in the different manifold and also, after changing my fuel system out, im having fuel flow issues. Do i need to recalibrate the cpu and will the cpu still work with the mustang conversion? thanks for the help.

 

I thought only the 351W's had the dual throttle body?

 

302 and 351 SD both had dual tubes. I believe the upper intakes are swappable between 302 and 351 assuming its not a HO or gt40 heads. The lowers are different tho. On a 302 I think you can run the mustangs ecu to support the injectors but im not 100% on that

 

You need to post a whole lot more setup info about your engine and mods before anyone can help you. Why are you running larger injectors? What are they rated for? I'd also ask this question in the 351w/302 forum. You will get better answers.
