I have a 400 small block with lots of fancy stuff but almost no power modifications.
I have a dual plane intake and some TriY headers.
For the rest the engine is stock. I guess 200 hp or so?
I purchased a 625 Road Demon and I installed it on my car directly from the box.
The car runs okay.
It spits out black residu on the ground when I hit the gas a couple of times while in park.
Also the car is smoking a lot when the engine is cold and first started.
I also notice a very heavy usage of gas. I remember about 18miles to the gallon(I had a 500cfm Holley) but now it is not more than 9 miles to the gallon.
Are the jets of the 625 to large?
