New Timing Gears

[cngordon]

Installed new timing gears (plus cam, lifters, rods, heads, rockers) and got myself confused (easily enough done).

Lined up the 0 mark on the crank gear (at top) with the dot on the cam gear (at bottom)as shown in the diagram below. Started setting rocker adjusting screws (zero lash + approx 30 thousand).
Somewhere I got the idea that TDC number one (about to enter power stroke) would be with the timing gears as stated above, but I had to rotate the gears so that the dot on the cam gear was at 180 degrees from that (at very top) to achieve this state.
Seems impossible to get this wrong, there is a keyway on the crank and a dowel on the cam gear, only one way they go on.

So the summary question of this rambling is "Should the #1 cyl be about to enter power stroke or intake stroke with the gears as shown in the diagram attached?"

Should be entering the intake stroke.

What timing chain and gears are you using?

There's no manual anywhere in the world that discusses this as far as I know. I've never seen one. If you line up the dots as your picture describes above and stab the distributor in on #1, you will be 180 out. When the dots are lined up like that picture, you're timed up on #6. That's how I always do it. Just time them up on #6 and let um fly.

Yes entering intake stroke. Then when the timing mark is on top of the gear, then you are beginning power stroke.

Dot at top, entering power stroke for #1 cylinder. Dot at bottom, entering power stroke for # 6 cyl.

The pros and cons on using a degree wheel vs the dot method has been discussed on forums for years. There's NEVER no mistaking where the cam is set when using a degree wheel no matter if there are machining mistakes or lose tolerances in the making of the cam, crank gear key ways or drilled dowel pin holes and believe me, I've seen all of those.

"What timing chain and gears are you using?"

Timing gear set is in a box that says it's from JP Performance, Performance Billet Gear Sets, Manufactured in Australia. P/N JP5989, Chrysler BIG BLOCK 383-440.

Not sure how my local speed shop acquired these.

E'xac'ly "By the book" puts no6 ready to fire, NOT no1
