Re: Aftermarket fuel injection
The Upper plenum is the same but the 302 and 351 intakes are not interchangable because of the 351s increased deck height. So you'll have to find a 351 lower. Also if the setup is Speed Density, I would think that running a 351 with a 302 computer may not make the best running motor. Speed density will compensate - to a extent, I wouldn't know if it would matter to much.
