I think with an 850, you'll be "under-carbed" but ultimately it depends on what your goals and budget are for the car. I'm currently in the middle of a Trick Flow head swap myself but just before I did I went racing one last time with my old combo but I used a Holley 950 hp carb versus my Holley 850 double pumper. For my combo, that carb switch was good for 2/10ths and 2 mph in the 1/4 mile. My combo definitely enjoyed that bigger carb and it's pretty "mild".

Since you have 500 ci, it will definitely love a bigger carb. If you don't have a carb yet, I'd go with a 950. It will definitely give you more power. If you already have an 850, start with that one and upgrade later down the line.

Good luck!
