drop a 750DP on it and run even faster...



You're comparing a #1411 750cfm Eddy which is basically for a gas mileage stock BB motor with a 800cfm Eddy performance carb??? The #1407 WILL run better than the #1411 as it's set up as the performance 750cfm carb. I think on a warmed up SB motor the #1407 is a good choice for the price.

Apples and oranges comparison. Try again please! I do agree with you that Holley will outperform them at the track but not everyone likes to run a Holley. I ran a 750cfm Holley on a stock 72 Demon 340 I once had and it ran great with it.

I've used Holley, Edelbrock, Carter AFB and Thermoquad and each has it's own advantage in some way.

One other thing is the guys running 600-650cfm carbs on their warmed over smallblocks and 383 motors are giving up alot of top end performance if you ask me. I ran a tweaked #9636 Carter AFB 625 on my old Duster 340/508 cam then switched to a big block 73 440 850cfm TQ. When you stomped the gas pedal at 40-50mph the difference was like night and day. Low end response was the same.

Match the carb for your motor & drivetrain plus your use of the vehicle is the best advice I can give.



The 1411 in that test - If you would have read the arcticle of course

A) Had the Choke Plate Removed - Shaft

B) Had Richer Metering Rods Installed

The 1411 comes from the Factory 2% Leaner then the 1407 - Yawn

So With him changing the Metering Rods to a Richer State in that Test

Apples to Apples , there both Junk
Eddy 800 is far Superior in every way on a BIG BLOCK

And this whole Topic is involved around BIG BLOCKS , Not Small Blocks
