Reply to "Manifold Question - Performer vs A331 Torker"

Fuel economy is of zero importance to me on this car. Not that I don't care about mileage, but I have a miata in the garage that runs great and still gets 29 mpg when I feel the need to conserve. I'm really more concerned about driveability and not having to have it tuned every 6-months. Bottom line - when I punch the gas in 2nd gear I want this car to come alive and roar to life. The stock setup that I had was, well - disappointing. After spending several thousand dollars on the rebuild, cam, heads, etc - I don't want the carb to be the weak point.

I'm not an engine guy which makes this a little tough as everyone seems to have a different direction and point of view. Sounds like something between a 650 and 750 is where I need to be based on general comments so far. Is there a reason you don't recommend the 850? Is it just overkill in this application or could it actually reduce performance?

I don't have the cam specs with me - its aggressive, but not radical. I'm also told the compression will be around the 10:1 if this helps. The car has big bore headers if that matters. Again - appreciate the feedback.
