to make a gm hei conversion what parts- hei modules are used and what type of coil to use with it?been following this post..thanks
I went to a large E core coil, original application 1990 F150 with a 351. Cost about 9 bucks, and (per their charts) it is also compatible with both MSD6 and 7 series ignitions so it's pretty universal.
For the module I looked up 1979 Corvette, but I think they are pretty much all the same.
Makes a nice spark.
Here is a thread I posted about it awhile back.
https://board.moparts.org/ubbthreads/ubbthreads.php/topics/2291558/1.htmlI've been thinking about making a batch of mopar-specific coil brackets for this setup but don't really know if they would sell. Seems most Mopar guys have not discovered the TFI coil yet.
