Ohio or Molnar crankshaft?
Tom Molnar makes some quality stuff even if his forgings come from China. There IS a difference in the suppliers. One of my engines guys buys a lot from Molnar... nary a problem.
I have heard good and bad about Ohio stuff.
The low cost line from Callais is also an import forging.
The tariff's should not affect the availability of any parts... that's 25% on wholesale costs not retail. Some suppliers will mark up according to their actual costs... some will bend you over and blame the tariffs.
I'm looking for aluminum sheet for my dirt car body. Most is imported. Two years ago, before the steel/aluminum tariffs, a 5x10 sheet was $67.00. Last year $72.00. Today $75.00. Does not discourage me at all.
The coronavirus hype will affect supply more than the tariffs.
