I'm not saying that a smaller carb can't make a lower ET at the dragstrip but for me the test at the dragstrip they used to confirm this was not conclusive proof. There may be better test out there to use as evidence. The article is written in a way to make you believe that the reason the car...

What is the data acquisition system you are using? Thank you.

This bit of information here is what gave it away. Good for you to post all the information you had. Glad you have it running.

I have a few of questions about this statement. You may have answered these already so bear with me. What is the voltage at the battery (volt meter + to batt+ and volt meter - to battery -)? With all the wires connected and the key in the run position . With the meter - connected to the...

It's been a while since I did that testing. We have to run a holley 4412 so the testing was done with a couple of different 2 to 4 bbl adapters and a couple different 4412's. If I recall correctly the power was similar with the 8022 making slightly more. But on my motor the ede. had better fuel...

Yes

About 4 1/4" in front and 5" in back.

The intake is on the motor. I might have another one that's off. I'll look tomorrow. If nothing else should be able to get a measurement off the one on the motor.

What measurements do you need? I can measure mine if you want.

no

The Edelbrock is shorter than the weiand. I think pretty close to the stock manifold and much lighter.

Why wouldn't you want to use one of the aftermarket aluminum intakes that are allowed? . INTAKE: Must use unaltered aftermarket aluminum intake. Allowed intakes are Weiand GM #7547, #7547-1; Ford #7515, #8023 or #7516; Chrysler #8022; Edelbrock GM #2701; Ford #7121, #7181, #7183; Chrysler...

Not sure what that is. Here is a wiring diagram. the thin red ignition wire needs to be connected to 12v source that has power when cranking and in the run position and no power in the off position. heve an assistant help you check voltage at the thin red wire. Google Image Result for...

In post 1 you mention you have a msd 6a. Is the thin red wire for the ignition wired to a switched 12volt source and not through the ballast resistor? I had a customer bring a vehicle to me with a hot soak no start issue that had been going on for a couple years. Car would start fine cold, he...

You have some conclusions about zinc that do not agree with what some others in this thread are saying. There is nothing wrong with that. I suggest with an open mind you present your conclusions to experts in the field tribology and get their input about what effects zinc has in oil and what...

The test could be done with different levels of zinc. It wouldn't have to be with or without.

I could be wrong but if I remember correctly the EGR should be closed at idle. I remember when I worked at the dealership diagnosing vehicles with a rough idle by using a screwdriver on the stem to pry open the egr valve and then letting it snap shut. Sometimes this would unstick a stuck valve...

Are you sure it's blocking it off? I can't remember how it is configured. On some chevys a flat plate won't block it off.

Is there an EGR valve on the manifold? If yes is the valve leaking or stuck open? Is there vacuum going to it at idle?

You said the cam is broken in already and I assume the rest of the motor is too. So you don't need break in oil any more. Now you need racing oil for flat tappet cams. There are many oils that are suitable for this. Take your pick. As a hobby stock you will probably put more or less 30 laps on...

What do you mean by "oil is changed after each session"?

Good eye.

Street car stud (1/2") on top and circle track (5/8") on bottom.

He is using them on a circle track car. The wheels will be taken on and off, slid sideways through corners at a high rate of speed, (sometimes on tracks with deep ruts) and ran into by other cars on a regular basis. It's a different world than running them on the street. There is a reason...

Floater

5/8" Studs front and back. Coarse thread is more popular at the dirt tracks around here. It's not just a bigger stud, the lugnuts are bigger too. Edited to say 5/8" instead of 1/2".

That's cool, thanks for the update. Good luck with your project. Send pictures of your progress.

Do you know if the op has had the motor running yet?

I'm not sure what you mean by clacking and clattering all over the place. Do you mean while he is cranking the motor over for a compression test?

It can be hard to get accurate numbers at full throttle and low rpm on a chassis dyno.
