Do you guys have any thoughts on intake manifolds for a setup like mine? I hear alot of guys running Edelbrock intakes. My Brodix HV is basically untouched so Im wondering if I should have it worked on or buy something different.

Here's my 2 cents. The 1250 is probably a LITTLE to big, but since you already have it it's free. Right? It might actually run a little quicker and faster with a little too big carb, but consistency will suffer. A 1050 would be more consistent. JMO. I'd try the 1250 and see if it does what you want after proper tuning.....

Tod74 the carb was just a little over $900 and picked up a half tenth on an already perfectly tuned engine.The car runs 5.30's 1/8 at 2500lbs on gas.The engine is a n/a conventional head 540ci.Just think if he went to alcohol.

carb
It had a 1050 Quickfuel carb, was perfectly tuned the car ran 5.40s, then switched to the 1200 pro systems carb and after that it ran in the 30s with only a carb swap.I am not trying to sell their carb,this is just the good experiences i have seen with pro systems.
