Bewy it has two wires that go straight from the distributor into the msd 6 box. It's not a 6al
Just a plain 6 box. So yeah it would be voltage sensitive
Car has a brand new battery 2 months ago. And its always on a battery tender when I don't drive it. It hasn't shown low voltage...
SOLVED!
My MSD blaster 2 Coil was weak
Once I swapped it ,instantly stopped missing, and I was able to get the timing back down where it should be.
Bewy vacuum came up, it's at about 12 now
I'll recheck it soon
Thanks everyone! I really appreciate all your responses
Ok my friends, I took a moment and used a piston stop tool . I rotated my engine by hand till it touched the piston and stopped. Made a mark on my balancer, then rotated it backwards and made a mark on my balancer , and well what ended being in the center is the top dead center mark I was...
Ok here's something we never talked about
My main body upgrade has primary jets 72 primary and 84 secondary
That's probably overkill and not helping. .I have a set of 67 and 76 I will put in.
I can get NGK 2238 in heat range 5.
It has the 5/8 socket for my headers.
So for the ease alone of not fighting the 13/16 between those pipes it's a good idea. My old 360 has NGK and it never had fouled plugs.
The champions everyone recommended the parts store wants me to order a case of 24...
The heads where redone and they got new bronze valve guides installed. Brand new valves from Hughes engines. There's no slop there.
It could be poor audio from my cheesy camera. I can plug my stethoscope on and listen
here's a video showing what the car is doing
Details on the engine
answers to some of your questions, I haven't tried all of your suggestions yet, but quite a few
In this video I lean it out and try taking the timing right down to 5 degrees at about 600 rpm and even if I take the timing all...
Excellent is that the 5/8 one ? Cause the big 13/16 ones are impossible for that driver side rear #7 between the headers
Hey I am making a video , off exactly what I have , what is happening and trying all of your ideas everyone I really appreciate the help!
At idle and lower rpm it happens
Just a pic to show you what the engine looks like. I know it's incomplete and the linkages aren't on in the pic.
It's got a factory mechanical fuel pump
I had a machine shop do the heads and they have brand new comp valve springs. I cc them and there was no leaks
I have super thick gaskets and locking bolts. The exhaust is super tight. All brand new.
It's like a misfire or unburned fuel
Nothing backfires through the carb
