So what did it make? That sounds like a solid setup and street friendly.

I am guessing it either did not make what he thought it would, or he broke it. Thus the Crickets.....

He hasn't run it yet, but I bet he runs out of injector.

I hate posts like these. These should be locked until dyno results are already done.

Well it failed horribly. Car made 340 at 4000 rpm and was blowing out the spark. Motor has oil pressure still so that’s cool. Does anyone make a decent 90 degree wire I can’t seem to find any.

Why on earth would a car "blow out spark" with such low cylinder pressure?
You have a different problem.

I ran a stock TFI system at 20-25 pounds boost and never had spark issues. I used Ford Motorsports wires. I could gap the plugs at anything reasonable, from .025 to .035, and never had an issue.

I'm running 30 psi at 8K RPM now and use a little CD ignition box just a little bit better than a 6AL. Summit 8.5 mm wires. Ford OEM 1989 distributor, and I run the gap NGK sells the plugs with. I can run plugs all season.

You have something else wrong. You have a bad wire, poor ignition, spark scatter from some distributor issue, wrong plugs, poor fuel mixture, weak valve springs, ground loop, or something. I wouldn't be afraid of OEM wires and the TFI system at that airflow and pressure level.

I have some dyno video but can’t post it. The tuner added fuel and it made no difference. The car runs and drives great but you jump on it and it brakes up. The heads were done and my machine shop helped me pick the right springs out so I don’t think that and he came to my house and helped me shim the rockers it’s pedistal. I’m going to try a new coil and wires and then no idea. It has a msd distributor. I have ngk tr6 plugs gapped at .30. Any advice is greatly appreciated.

The Motorsport wires are fine. Depending on your setup, you might need to wrap them like I had to. so you don't burn them up. I don't know how old your wires are, but I had a good used set sit around for a number of years before I used them again, but they turned to junk. The motor came alive with a new set. Maybe you just need a cap, rotor, and wires..

I did some research on spark gap, and from what I read from some experienced racers is that there's nothing to be gained by running a big gap. .030 is the borderline and that .032 would give guys problems. It's harder to jump the gap with increased fuel and boost. Try running .020 and forget about it.

I gapped mine a .030 but started to get some breakup even with an MSD. I pulled the plugs and found that a few opened up to as much a .034 at only around 3000 miles.. I'm doing maintenance right now, but will run a new set at .020..

Alright update. I re-gapped plugs to .24 and discoverd one of the plugs had a crack in it. I put on new wires rotor and cap and took for a ride. It pulls good all the way until 6k and is on rich side 10.2 afr on Aem wideband Gauge. Going to bring back to dyno and see what it makes. It’s pretty quick for what it is I am happy with that.

Congrats!
It will pickup even more when you lean it out to about 11.5.
