I didn't recommend it, just said it would work..Our tiny ignitions will throw a 3/4'' spark in dry air...I have a custom C&H here that will spark 1/2'' at way over 20,000 rpm....Works just fine in our racing GT80s and 289s, and will be in our new hot rod 40+ hp ZDZ 210....

Can't verify the 40 hp yet, the dyno is not quite completed..
I can still build a few of these with Syncro Spark timing control but they won't be cheap.
