258 timing question

Hello,
I am installing a used 258 in my jeep. There was not a distributer with the motor when i purchased it. I am unsure if i have it installed correctly. With the "notch" on the harmonic balancer at 0` which cylinder should the rotor be pointing towards in the distributer. Thanks in advance for your help.

Re: 258 timing question

Hi and welcome to the board.

You have an old CJ [img]/ubbthreads/images/graemlins/thumbsup.gif[/img]

Here are some old threads on the subject of timing (and related things). There are plenty more if you do your own search.

<u>GM HEI Install</u>

<u>Timing advance</u>

<u>Weber and Vacuum advance with GM HEI</u>

Last but not least an old rant of mine:

<u>Timing and Fuel Delivery, some thoughts... </u>

There's lots more there than you asked for, but most of it is worth looking at.

Again, Welcome

Re: 258 timing question

well actually i have been around for 5 years. my old posts must have disappeared because of non use. i took the old distibuter out of old motor and put it in but it would not fire. messed around with it. flipped it 180` checked firing order, ya-da ya-da. started going back and checking voltages at coil etc. and found the dropping resistor for the ford hi-energy coil conversion i did 4 years ago was broken. must have happened during rewiring and new split loom tubing. a hole the size of a football in side of block lets ALOT of oil out. anyways i replaced resistor put distributer back where it was originaly and the bad-boy fired right up. thanks for your help. attached is picture of old motor. check out the hole at front of the block. number 1 rod, well what's left of it is on my workbench. i drove it home the 5 miles after it threw the rod. i started it up and drove it into the garage to pull it. nobody at work beleived that it would still run so i videotaped it. what a racket!
