This is not the firing order that is stamped on the coil packs.
Coils are matched by 2 pairs of cylinders for ignition spark plugs and coils system.
1- Like 5 2 and 3 6 and 4 1
2- Pairs of 2 cylinders are firing at the same time.
3- When cylinder number 5 fire at ( Power Cycle) the cylinder number 2 fire but in ( Exhaust Cycle ). That is why you have those number stamped on the coil packs.
I guess my first question would be - what are your plans for the car ?
Totally stock, modified, or race ?
Totally stock would be the most valuable in terms of resale. Modified or race would limit the number and type of possible buyers.
It had a straight 6 cyl 250 - a 350 V8 - or 400 V8 when new. The VIN would tell you want the original engine was. And this was before GM swapped engines between brands. So the V8 engines were Pontiac built. The Pontiac 6 cyl was overhead cam.
Well, according to Pontiac Power online, a 65 or 66 Pontiac engine with XB is a 389 with a 2 barrel carb, but it was used in the B body which was the Catalina and Bonneville. A 67 engine with XB is a 400 with a 2 barrel carb. 0489308 does not show up on the list. Casting codes from 19064 to 1968 started with 97xxxx.
What kind of Pontiac engine you have? Is it pre-80's? Pontiac engines have a 2 letter stamp on the front top passenger corner of the engine block. The year is usually next to the distributer hole, and the actual casting number is located on the top rear of block. Some sites offer casting number searches. A good one is wallaceracing.com. They deal with everything from block and cylinder head numbers. If the engine is 1970 or newer, engine size is casted behind the dipstick passenger side of block and also on the front driverside of block too. There are many different variations of codes to list. A example it the engine is made in 1967, casting number is 9786133, code on the right front of block says YE, then it's a 1967 400, that originally had a automatic transmission connected to it, had 10.5 to 1 compression, #066 camshaft, 143 or 061 cylinder heads, 4bbl carb, and 325 horsepower.
Pretty skimpy info there toolbox. Which engine do you have? In 1967 Pontiac made 326, 400, and 421 engines. They all have the same main bearing size, 3.00 inches, rod size, 2.250 inches and the same stroke, 3.750 inches. In 75, they only made the 400 and 455. The 75 400 uses the same crank but the 455 uses the same rod size but a larger 3.250 main, and 4.210 stroke. So any year 400 crank will fit any other year 400, 389, or 350. Google Kauffman Racing, Wallace Racing or Pontiac Dude.
Nothing under that number comes up on their web site. You should give them a call on thier tech line 662-892-1500. They are open Mon. thru Fri. 7 AM to 6 PM CST. Hope you get the information you are looking for.
well not sure exactly why it wont line up use something to turn the crank and cam to appropiate position start sliding crank gear until cam gear is touching then start to push both at same time make sure your crank key and cam pin are bothin place
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another.
if you have the engine out itheir is a vin num stamped on the rear of the heads ,olso if its a small block shuch as a 350 327 305 or even the 400 small block90% of the engine parts are enter changeable,
their shoulf also be a vin number stamped on the block right above the top bolt of the water pump on the drivers side
