Not quite as extreme on the SJ forums, but similar. So alot of guys were doing this 'TFI conversion' which left something like half of them stranded because they cut out the resistance wire and increased the coil voltage. The Duraspark isn't a bad a system and they would have been better off leaving it as it was. They didn't understand the later coil was used with a controller that regulated coil power like GM did with the HEI module.
