Having a mechanic or repair shop replace the timing belt (and possibly the serpentine belt and accessory belt at the same time) can cost $150-$1,000 or more, depending on the make, model and type of vehicle
To do this, measure the circumference of the balancer with a flexible, cloth or paper tape, measurer or install permanent degree tape to the balancer Once you have that set to what you want, say 14 degrees BTDC, you then check the total timing by reving the engine to over 3000 rpm (or whatever RPM that the timing finally stops advancing) and check the timing with the timing light again using the total advance tape on the balancer . The ignition initial timing, total timing, advance curve are what is being worked on for now The 400 was inspired by the Pontiac 389 V8 and proved to be the last Pontiac engine with closed chambered heads .
You should see total advance before 3,000 - 3,200 rpm
generally there is no reason in the world why a pontiac 400 or 455 ( as I assume is the most common engine mentioned in this forum ) should ever drive with a initial timing below 10 GM adapted the J-body cars and the all-new for 1982 J2000 (later renamed Sunbird) had a convertible as part of its line . Pontiac was already over on the Tempest V-8, so Pontiac engineering decreased the bore on the Tempest V-8 to 3 For mechanical advance (with the vacuum advance hose to the distributer removed and plugged), I set the timing at 32 degrees BTDC at about 2600 RPM (you'll need some timing tape for this) .
68 and newer open chamber Pontiac heads tend not to need as much total advance as do the earlier closed chamber heads (especially the 67 GTO '670' heads)
Depending on your budget you can get a really good Allstar Performance ALL90019 Timing Cover for Pontiac V8, the more you spend the more likely you are to have quality components way for most people to set the timing, and is not a good procedure for optimum performance . Installing a timing chain and gear set on a 78 pontiac 400 engine i need to know if someone knows what side of the balancer it is supposed to be on and where the mark on the balancer is supposed to point at TDC .
Selecting a Hydraulic Cam for your Pontiac Engine
Timing the ignition, then, is a matter of getting the timing correct at one end (idle or full advance) and letting the rest of the range look after itself The other brand timing lights are hit or miss, it appears some brands are just rebranded versions of either the Innova or Actron models . In this Hagerty DIY, Kyle Smith walks you through the process of adjusting timing on a Chevy small-block engine It has a 400 ram air engine with an HEI distributor, 8 .
The Pontiac 400 cubic inch motor (made between 1967 and 1979) is still a great platform for a high performance daily driver
An experimental Pontiac 6 with an aluminum intake manifold dual carburetor set-up was built in 1945 The whole motor is rebuilt and the cam is now an Edelbrock performer cam with an Edelbrock performer intake and a thunder series carb . Please contact us to confirm correct vehicle fitment and usage Can anybody detail the procedure for replacing the timing chain on a original 400, I have the Fisher body/mechanical guides but they do not discuss the procedure .

WATCH YOUR IDLE RPM WHILE YOU SET INITIAL ADVANCE TIMING!!! You note that the centrifugal advance curve that I recommended above starts at about 800 RPM
A mechanical advance curve that provides 20 to 24 degrees of additional advance can provide the optimal amount of total spark lead required for peak performance To that end, they included a hood scoop and fresh air intake, but tweaks to the camshaft, cylinder heads, and exhaust manifolds were key as well .

As piston speed increases, spark timing must occur earlier in the rotation cycle and a mechanical assembly within the distributor increases spark timing

If you set idle timing to 10 degrees BTDC, and there is no vacuum unit, and you want 36 degrees total spark timing at road speed, you can set the mechanical advence limit to 26 degrees If you want 35 then set it there at full advance and see where you end up on initial .
Your dwell, and thus your points gap, needs to be set before you get out the timing light
Get engine to running temperature and check ignition timing The carb does not seem to meter well until about 3500 RPM .

If you have a vacuum unit that can produce 7 degrees advance, and you want to set idle timing at 15 degrees BTDC and limit maximum total advance to 36 degrees I will dig out an issue of High Performance Pontiac that I got a few months ago as they had a great article on cuting marks in the balancer for figuring total timing .
We recommend that you also bring it up to about 100-200 RPM above where we set the total at and with a dial back light check to be sure that it doesn't exceed the total timing we have determined as Max timing for your application
The reason the GTO came out , was in order to remain #3 in sales with a performance image and your not allowed to race, was to take the performance off the track and put it on the street To set the timing you first have to get the motor to TDC (Top Dead Center), the is where the #1 piston is at the top of the block . Have seen info that says set cam gear at 12 o''clock/ crank at 12 0''clock The Pontiac specifications for both duration and lobe placement should be used as the starting point for cam selections in both street and street/strip cars .
