Get a dial back timing light. Only time the engine for total advance. 36 degrees all in max. Using an initial timing setting is a disaster waiting to happen. You have no idea about possible mods to the distributor. Also, verify the outer ring on the balancer has not slipped. Easiest way I can think of is to take a known good balancer, pull your crank pulley off and carefully compare the keyway orientation to the 0 degree mark on both balancers. You can also figure it out using a degree wheel to locate TDC but that is a lot more work. Good luck.

My 1967 Belvedere II is a 383 4 barrel car with a 4 speed. It has the 68 383 hp cam (268/284 .450"/.458") and a 68 intake and carb with 68 exhaust manifolds. It is a low mileage car, but was drag raced in the late 60s. I took it out the other day. Although I have owned it almost 4 years, I've never tried spinning the tires. I tried to do it from a 10 mph roll, but it wouldn't do it. It didn't bog, but he low end just feels lazy. It seems to run really good once it gets to 3000 rpm.
Shouldn't it be able to spin bias ply F70-14 tires? Not that I am trying to win a burnout contest. I've just always felt the bottom end performance was lacking, so I did it as a test.
Thoughts?
EASILY..MINE WOULD FRY EM FROM A 25 MPH ROLL..HAD 3;55S

No, Dan. That is false. Try responding when you sober up.
Aw C'mon now, my 61 Dodge Seneca with a 225 and Spark-O-Matic shifted 3 speed beat every taxi cab in San Jose and smoked the tires all the way through 3rd gear, (the smoke may have partly been due to the exhaust being routed into the rear wheel wells LOL )
I will admit that some of the taxi cab drivers may not have known we were racing
With all these "no it won't" answers I'm wondering why not. I had a stock 69 Superbee that would light em up at a roll. Stock 383, 4speed, 3:55 rear and F70's. The first time it happened, it surprised me but, it would do it consistently, dry asphalt, 5-15 mph.

Wheel spin has much more to do with the tires than engine power. Goodyear Polyglas and Polyglas GT lit up with ease. Penny's Scat Trak 60's were tough to spin. When we bought my wife's '93 Ramcharger, whatever tires were on it, could hardly keep it from spinning. When I swapped the Michelins off her old '84 Ramcharger, wheel spin went away.
Just for fun, videos from back in the day, a '69 GTX auto and a '69 Hemi Charger 500. Note the wheel spin on what I suspect were factory original Polyglas tires.
With all the yes it will no it won't one thing that has not been mentioned is pavement conditions. IE: wet, dry, dry but dusty, sand, salt etc.
Uh, I did!

Some are missing some important facts here. it is a 67 383. It has a 68 cam. It was drag raced in its past. What is the OP definition of "burn the tires"?
Lots seem to want to compare a 67 383 to a 68 or 69, or even a 70 383. The 67 still had the low, flat intake and likely lower compression and would have been a lower HP then the 68-70 versions. There is no mention on which intake it has. We have no idea how that 67 motor is/was. That is important. It has a newer cam, We assume it was installed correctly, but maybe not. All mechanics are not created equal either. Just a cam swap might have made it better, or worse then it was originally. All 383s were not created equal, right out of the factory, one car to the next in line, some ran better then others, and some much better then others. Was this 383 a weaker one? There could have been lots of improvements on the rear suspension to add more traction during its drag race days, or not. We have no idea. We don't know anything about the condition of the clutch. or the rear end, or the trans, or the suspension, all of which could play into spinning the tires. We don't even know for sure what the OP's opinion of "smoking the tires" means. Is he expecting a bleach burn out type of "burn the tires" or a break the tires loose kind of thing. Maybe he is expecting black marks left on the street, do the modern Polygalas tires leave black marks? Not many modern tires leave black marks anymore. Could be he is spinning the tires and doesn't know it because there is no smoke, no noise, or no marks on the street.

In my original post (might wanna go back and reread it), I mentioned it had a 68 cam, intake and carb installed along with the later style exhaust manifolds (not the original logs).
Regarding the mechanic that installed the cam, carb and intake, it was Carlon Hine at Hine Motors back in the day. I’m pretty sure Carlon knew what he was doing. At that time, the car did have headers, but they were removed later on in favor of the manifolds after it’s drag racing days were over. When it was drag raced, it ran 14.30s at 98 mph with slicks & 4.10s and was class winner at York US30 dragway as well as Sunset Drag Strip. 3.23s were put back in after it’s drag racing days were over.
It does have an adjustable pinion snubber, so maybe that contributes to the lack of tire spin.
Maybe burning the tires is a bad choice of words. I just thought it might be able to at least squeal them a little bit. Not expecting a funny car smoke show.
'67 is an abbreviation of 1967 67' is an abbreviation of 67 feet They are not interchangeable.
(the smoke may have partly been due to the exhaust being routed into the rear wheel wells LOL )
