500hp Carb Conversion
 

Has Anyone ever changed from carbs to elctronic fuel control on their 500 hps, having an issue on one, just about tired of it.
what are some good options?

I use the Holley MPI kit. It has a single plane manifold with a 1000CFM throttle body. I upgraded the injectors to 42lb. It has a laptop programable ECU that you adjust on the fly. Are you a do it your self person or will you have to pay to have it done? It is very time consuming. It will probably not give you a big HP gain, however it will start and perform better. The kits are not cheap about $3000. You may be able to find a factory setup from a 500MPI.

Would probably be alot cheaper/easier to send your carbs out to Nickerson, and have them go thru them. It will be better than new.

Stick with carbs.

EFI is nice, but for the money I would put it into some more go fast equipment.
