Old Jacob's ultra coil any good?

Hey everyone,

A few years ago I found an old Jacobs ultra coil at the pick N pull and got it for $3. I always thought these things looked pretty cool. Well I found it yesterday in my Garage and was thinking of putting on my truck. It's a Chevy 383 with a Davis DUI. I'm currently running a PerTronix Flame-Thrower coil with no issues. What's the verdict on these?

Thanks

Hook it up and see... I've had a Jacobs ProStreet Ignition on my '95 GMC for 14 years. Have never had an issue.

I found some really good info on these coils, Shoptalkforums.com • View topic - High Energy Ignition Systems Jacobs MSD Mallory

I'll hook it up next week when I get some spare time. I fully expect a 1" spark plug gap, 5 mpg's and at least 40hp
