What are the maroon filter worth? I think I may have a new one in storage?

I think the 715 is pretty well dialed in. Drove it today, and the 4th gear pull from 2,500 rpm is smooth. No bog or hesitation!

Thanks all for the help

Adjusted the mixture screws out an 1/8 turn and changed to a #31 nozzle and the car responded with a steady pull in 4th gear without any bog or hesitation.
Going to run it like this for the week before going to #68 jets on the primary as suggested. Seat of the pants feel is much better.

I have a path to follow now after all the suggestions and help. It is a PITA while doing it, but a good feeling when you make positive strides. I messed with the fuel pumps and fuel systems, and after many tweaks, that has been solved.

I think I'm going in the right direction on the 715 tuning, so I'll keep everyone informed. Weather has started to cooperate, so I hope to have a well tuned
327 by the end of the weekend.

Thanks for the help!

Drew,

Thanks for the suggestions. It sounds like I do not need the 50 cc accelerator pump, so I'm going to turn out the mixture screw as suggested an 1/8 of a turn to start. May increase the shooter to a #31 as the next adjustment before raising the float.

Weather has mot been cooperating here in Central Florida, so hoping we get a few hours of clearing on Saturday. Will keep you informed

If this does not work, may try to find someone who can do air / fuel check on a dyno to try to speed up this process and dial it in?

Drew,

Will give that a shot!

No need for the 50 cc accelerator pump and adjust the secondary opening?

The carburetor is the latest generation as sold through Branda Performance. Not an original 65 or 66.

I'm running an electric pump to push fuel to the mechanical pump like the GT 350 Competitions. At idle, gauge is indicating 5 1/2 psi and under full throttle, it drops to about 4 1/2 psi +/-.

To start the car, I energize the electric pump and it pushes 5 1/2 psi to the carburetor and gauge. Turn key to start and car idles at 5 1/2 psi and cruises at
5 1/2 psi. Don't think I have a fuel pressure / fuel system problem as everything is new with less than 500 miles. It is a tuning issue to get the hesitation smoothed out. If I do a drag race start, car pulls hard in all gears. Only when running at a constant speed at about 2,000 to 2,500 rpm and mash the gas, do I get a hesitation, then a hard pull. Need to get the fuel delivery at that  instant to smooth out the hesitation.

Worked the fuel pressure issues out with an electric pump and new Carter canister pump. Fuel pressure is steady at 5 1/2 psi on the gauge. I think the 715 will be OK for the 327 stroker? I think I'm close, as the bog is slight and it will pull hard once past the initial hesitation.

I'm hoping that the 50 cc accelerator pump or maybe a power valve change will solve the issue. Bought a #31 discharge nozzle and will try that on Saturday or when the weather clears.

Thanks for the input.

Been fighting a slight bog when cruising at 35 to 40 mph then try to accelerate hard. The engine is a 327 stroker with X 303 cam, Cobra dual plane intake and tri-y headers. I currently have 67 primary and 80 secondary jets. Using the #2 position green cam and a #28 shooter. (Elevation is 20 feet above sea level in the Daytona Beach area)

It has been suggested to change the 30 cc accelerator pump to a 50 cc pump and use the quick change secondary housing for ease of tuning the secondary opening. Using a 3/8" spacer and Hi-PO open element air cleaner.

The car originally bogged when starting out, but changing to the #28 shooter, green cam in the #2 position and better adjustment of the accelerator pump cured that issue. Just need to get the "mash the gas" bog adjusted out. Once the initial bog ends, the car accelerates hard up to 7,500 rpm.

Any help getting me turned in the right direction will be appreciated.

Thank you.

I would prefer to have the outer stainless steel rings, as they typically have curb rash or dented from rubber mallets when installing.

I've used a few stamping companies for the former business I was in and with the 3D printing and digitized measuring and die making, I thought it might be worth investigating?

There are a number of stainless steel stamping companies that advertised as small batch specialists. Sure would be nice to have new rings to install the cast spokes too!

Thanks Corey!

I have talked to Tim in the past. Will give him a shout.

Eddie,

Good morning!

I did get a nice set of wheel covers from you. Just wanted to investigate if anyone ever thought of trying to get new stainless steel rings made before I try to find someone to restore the originals.

Does anyone restore the stainless trim rings on this site or have a recommendation?

Thank you.

Has anyone ever investigated having the 68 Shelby polished wheel cover rings reverse engineered / reproduced? Is there enough interest in having new rings
reproduced?

Has anyone seen the article today in the Detroit Free Press regarding a new, starting at $298,000 carbon fiber "Eleanor"? Twenty-five are to be built and listed in the Shelby Registry!?? Hopefully these are not included in any SAAC Registry! Maybe their own registry, but do not dilute the real cars with these recreations from "rusted" junk Mustangs. I believe the article stated that the Ford VIN's will be used and new Shelby numbers assigned. Just not right! What do you think?
