I dig the new system, reminds me of my buddy's old Torino he had

 

I'll have to get some better footage. Like a drive by and starting acceleration.

It has a loud spot right between 2700-3200 rpm. It changes tone and has a popping sound, then it smooths out again. Is that normal?

 

JEFFFAFA, I know your a fan of the glasspack rumble. Seen the new video yet?

 

I'm getting used to it. It does sound pretty good!

 

Sorry so long to answer Garrett. WAY behind on these threads. Phone has been busy.
I do like it but I'd have done Cherry Bombs. They're a tad mellower than your Thrush's. Sounds old school to me. Especially since I put a Thrush on my Dad's 63 Impala SS (283 P.G) when I was 16. I 1st thought of Pace Setter tips when I read you were not happy. Resonators built in. They are here in town out west somewhere. But they are only straight.
Your Eddy carb is too lean when it's transitioning from one circuit to another. That's why tone changes and it pops. Which makes perfect sense. Adding headers and free flowing exhaust always needs a richer set up in the carb.

No worries Jeff, work comes first for all of us.

I haven't yet re-tuned the carb so that could be possible.

 

Sounds good!!! Im running into the same problem with doing my exhaust the cross member in the way. Thanks for the pics guys. Now to make up my mind on how I want to do it.

 

I posted a new thread "how I put 71-73 mustang headers in my bump". A lot more pictures in there.

 

OK!
Here's some real action finally!

I like the new "growl" brother!

 

Frickin' Cool Garrett! Liked the tone but especially liked hearing the POWER of that clev-o.

 

Yeah, the tachometer runs up from 4 pretty rapidly haha. Gooood power up there!

 

Talking in the other "how fast thread" reminded me of this one.

My drag strip times and weights come out slow for putting out 350hp. Times and weight suggests 200 hp at the wheels. And I have a hard time believing I'm loosing 150hp through the drivetrain..... I don't think I'm really making 350. Even if DD5 says I should be.

 

Drivetrain HP losses are typically at 20-25%.

We'll go with the lower number and say 20%. IF the engine is making 350HP at the crank, with 20% drivetrain losses, you would net 280HP at the rear wheels.

 

Right. So if that's the case, 1/4 mile times should have been closer to 14.5 @ 93.

I ran a consistent 15.9-16.0 @ 83. Figuring a 4300lb race weight, that suggests 200hp.
