Hey guys, I'm sure I had crank at 12 cam at 12 o'clock when I stabbed the dist. I checked #1 at TDC, crank damp was lined up at zero and when I pulled dist cap, rotor was at #1. Would it even run 180 out? I'm leaning toward timing. Thanks, Jeff




You have it right , the engine doesn't care where you drop in the oil pump drive as long as the rotor is pointing at the tower your number 1 wire is on at the top of the compression stroke and the wires go in the right direction and order.

And NO the engine will not run if you are 180 out OR if you put the wires on in the wrong rotation direction.

I will have to disagree on the placement of dist drive gear. I thought that also quite a few years back. If the slot is not line up straight (slot front-back)and the # 1 is not in the position it is called for on the dist. cap it will crank up and run but not right.
I know you may not think this will help,but it will only take you a few mins. to try this.
If anyone else is not running theirs timed this way,try it and if does not run better feel free to send me all the Hate mail you want.

You can point the rotor to ANY tower on the cap and
it'll run perfect if you start the firing order from
that point... I dont ever locate mine the way the
factory says... I point the rotor to #1 plug/cyl

Going to have to disagree. With the cross rams we ran in the past, with a tach drive distributor, it was necessary to move the gear a tooth or two one way or the other so that the tach drive would clear the intake. As long as we moved the plug wires to match, it was fine.

This may sound stupid, but the main question, lack of revs...I'm assuming you have sufficient piston to valve clearance?

GREY NOT TO TACH,tach plugs into the slotted wire plug on the msd box



Don't know about a "slotted wire plug". The box has only one plug-in for the wiring. The instructions say the grey wire to tach. I just hooked it to the factory wire at the tach. Tach works normal hooked up this way. I don't know any other way to hook it up. Jeff

When you set up the cam timing was the crank keyway straight up or was it offset to approximately the 1:30 position.... Stupid question but I've seen it do exactly what your dealing with four times...



Hello! Crank key-way was at about 1:30 if I recall. Jeff

if your running a stock mopar electronic dist for example.you better make sure your reluctor gear (star gear pickup) is lined upwith the pickup when the rotor terminal is on a plug/cap terminal.
a stock dist can be phased 180* out..it will run ..but it will run just as described...like junk.
its pretty easy to check..on a stock dizzy ..
im not that intimate with the internals of the msd dizzy.

but to clearify..you can have the distributor stabbed in 180* off...it is possible and it does matter...look at the reluctor...phase.
if its not lined up over the pickup when the rotor is dead nuts on the cap terminal. you understand this issue..
fwiw...

msd box has no grey wire,maybe your tach wire is grey and pluged into the msd tach receptor.

How did you determine 0 lash??
I like to be able to see lifters so holding lifter up back off till plunger comes up to retaining ring then add pre load back in!

What valve springs are on the heads. If the heads came with roller valve springs and your using a hydraulic cam then the lifters may be colapsing because of too much spring pressure.
The digital-6 ignition will run like junk if the magnetic pickup wires are reversed.
If you have not degreed a cam before, you may have used the first lifter bore when degreeing the cam?
The first lifter bore is the exhaust lobe, not the intake lobe, so if you did this the cam will not be installed correctly. Double check the sparkplug wires firing order. The order on the cap is counter clockwise.

I would have said 5 and 7.. they're next to each other
and next in the firing... I've made this mistake
before when I was rushing to get to the lanes

I typed a very long P.M. and for some reason it did not go through.
Basically,it was just an offer for some help if you want it,I think you are down around Muncie?
I am close to South Bend. Just let me know,some sometimes it helps to just have someone else look at it with a fresh pair of eyes and ears especially when you are frustrated.
