I dont know how much steam you big block is making but on my high 9's smallblock i used to run that 1025RS carb. It worked awesome.


One night i took it off and put a pro systems prepped 1000 4150 carb on the car and it knocked better than a 1/10 out of it. I put my new 1100 pro systems dominator on it and it did no more than match the 1025rs, as i had just bought it looking for a gain, i sold the 1025rs i had for everal years and continue to run the 1100 dominator to this day.

Long story short, a trick 1000 hp slowed me down, a trick 1100 dominator MATCHED the 1025 race demon...this all on the same night testing at the track
