How do I contact eric (vintage muscle car) any one.

I'll do my best to verbally explain this since no one else has stepped up. I'll assume that there's no timing tape on the balancer. Take a measurement on your timing tab from the O-TDC hash mark down to the 12 degree hash mark. Multiply that measurement X 3 to come up with the distance where 36 degrees should be on your balancer. Mark this position with some white paint/chalk on your balancer, while revving the motor up to 3000 RPM, check where your timing mark is on the timing tab. That's the total degrees. I use a very simple Timing Light (without the dial) and make sure the Vacuum Advance is dis-connected. 36 Degrees total is a great starting point and motors are usually very happy righ there.

Just saw this post, had the exact same issue with my Deuce Todd. The jetting, total timing, and timing curve is critical to these engines. The fact that you can't break the tires loose without a clutch dump is dismal. (You will soon be able to break them loose from a 15mph+ roll, and get 2 ft+ out of the second gear hit!).

I have my setup in my glove box, I'll dig it out tonight and respond then. Special thanks to COPO Pete for my setup - it's right off his car! You might do a search here on the site for the thread where I went through this, my issue initially was an off-idle stumble - tracked it down the idle cam, got to use the white one, second hole..... stumble was gone, instantly!

13.50 @ 105mph, stock and on the skinnies! [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Marlin, You are my hero... I tried to send you a pm but mail box is full? Wow you have same prob. Yes it is depressing, all that compression and internals and 4:10 gears and car is nothing special to write in about. Im not looking to make a rocket ship out of it, but i knew there had to be more some where.Thank you for responding. Todd

As mentioned before, I am rebuilding/restoring the original owner's (Roofs) dual point, mechanical-advance-only Mallory YC-465HP distributor for my Deuce. Any recommendations on setting this up? Dwell? All advance in by.....? Earl Roof told me that Mallory dual point really woke his car up.

Good thread. Thanks!

Ok, the complete setup was not in my glovebox - but in a box in the basement [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img] Can't do me much good there, but....

My Carb setup:

Accelerator pump cam = white one, installed via hole #1
Accelerator gap at w.o.t. = .015
Accelerator gap at rest = 0
Accelerator spring = old style, no nylok nut

Secondary Vacuum Spring color = Yellow

Primary Power Valve = 6.5
Primary Jets = 72

Secondary Power Valve = Blocked
Secondary Jets = 82

Squirter = 31


Timing = ~36 degrees total, all in by 2000 rpm. Personally, I like the dial type timing lights.

Spark plugs = use the NGK's!!!!


Suspension setup:

Front tire pressure = 44psi
Rear tire pressure = 40psi

Front &amp; Rear shocks = good, basic gas shocks - can use 50/50's

Rear springs = 2 spring clamps on each side, both clamps in front of the rear wheels but on different leaf stacks

This setup should get you started, let us know how you make out.

OEM stock were 72 primary and 76 secondary, they were way to rich for the 1100 feet elevation here in Phoenix ...

the above may work ok for a drag car but will be &quot;phat&quot; for the street

again, IMHO, YMMV, etc

Very helpfull information.

Thanks to Marlin and Peter for this heads-up. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
