Mercruiser BBC EFI in a car? I've been planning on sticking a BBC in my car for a long time now. The major prohibiting factor has been money. After tons of back and forth decisions of EFI vs Carb I eventually gave up and couldn't see justifying the price of EFI right now. Then I came across a really good deal locally with a friend of mine who wants to sell his complete EFI system off of his Mercruiser BBC in his boat. The price is definetly right, so it got me thinking.
Would this work? I noticed just from looking at it that it's a very tall intake and would definetly require some major hacking of the cowl area, that can be done. What really got me thinking was of the PCM and what sort of controls it has. Would this function in a car. I plan to put this on a 454 with rectangle port heads, maybe a 468+ depending on $$$. Anyone have any ideas, thoughts or experience with Mercruiser EFI?
Thanks

I don't have any thoughts on the EFI, but you can look at the sticky how to and see what all I had to cut to get my high intake and carb to fit. You may actually have more room around the cowl than I did. If you could post a pic of the motor and EFI setup out of the boat maybe I can help you on the fitment issues.

I had another idea that might help with the fitment issue. Would it be possible to take an off the shelf intake and use all of the electronics off of the Mercruiser intake. Example: Taking an Edelbrock RPM air gap O, drilling and tapping it for injectors, making an elbow, and using the tb off of the Mercruiser. That would help with the size issues of the Mercruiser intake and allow me to use oval port heads, which come with the engine I'm looking at getting.

Same thing stuffed if a C4. It has a cowl hood, but fits remarkably well for its size.
You can also swap everything over to a carb style intake. And either use an elbow, or just get a 4 barrel throttle body. Whatever clears best I guess. What kinda RPM do you want to run. These are kinda restrictive. Ther're supposed to run out around 6 grand, maybe a little sooner. We're gonna put this one on the dyno someday.
