Hi evryone, I'm new to this site and been a tin Indian fan Many moon's!
I've just finished putting together a 70" TA that Ive had for several year's.It's got the stock RAIII & 4 spd. It had had an hei upgrade prior to me.Now,I put in a new wiring harness from ames perfomance and new Petronix flame thrower distriburtor. Checked with harness maker
Reproduction Wiring Harnesses for America's Muscle Cars tech's to be sure I had all the right wires going to the right places sense it's now HEI instead of point's!
Got the big green light! (also change feed wire from firewall harness to bat. connect
on distributor to 12ga.) New set of accell plug wires and set of ngk plug's gapped at 45* for this engine. Triple checked my timing (more like a zillion frigin times as well as firing order) using chilton shop manual for back up! SO here's the problem, fired it up and it ran for about 15 sec. on all 8 sounded good!! Then skipped down to 2cyl. on left bank & 2 cyl. on right. Pulled plug's... wet on non firing cylinder's (gas). Changed plug's hopping just by chance bad set...SAME thing.
Pulled cap,rotor and modualar. Tested with testing unit from snap on , say's no good!! Cool, so i get another modulator and put everything back in... SAME FRIGIN THING!!! Pull and test modulator and this time it test to be fine but still same no fire on same 4 cylinder's. Next i try the plug wire's, hopping
No luck there.. Changed out distributor to another petronix flame thrower and same deal !! So last thing I check voltage from wire that was up graded as mentioned from wiring terminal to dist. 12.4 volt's on meter. I'm sayin uncle, any idea's out there???????

It's got to be something simple and I'm just not seeing it.
