Cant convince ol smurfy that though.
He swears up and down this monster carb is perfect for that baby motor.
Let him run what he's got, we cant make that motor better for him.
Not by sharing our honest opinions here on the forum which is what he is asking for when posting here.
Oh well

actually he was just asking for HP estimates.Didn't intend to turn it into a thread putting down his choice of carb.Sometimes I have trouble keeping my opinion to myself.As I said,if he likes it I love it. It's his engine.

I agree with Todd on the average set up like yours. However, it's impossible to give you an exact number without putting it on a dyno or at least knowing some #'s from the track. You just may have the 1 in a million 875cfm gulping motor that only needs 1 7/8" headers to make 700hp, but I may be way off that # too. 875cfm is about enough to run a mild 548.
If you didn't think you would get some good advise from guys that knew, you would not have ask so don't be rude to the guys that just answered your question and gave you their opinion and trying to help.

hey supersmurff your car will run alot better with a smaller carb (650 - 700) and even you header tube size is too large for your combeo probably a 1 5/8 or 1 3/4 inch tube would definitely give you more torque and Horsepower. just my thought. i race and i kinda know this stuff art
