I'm ready to order pushrods for my 350 and would like to know who to order from TA or Smithbrothers ?
I vote for MEASURE twice cut once.... Use some adjustable pushrods from TA to find out the exact spec for each of the pushrods. Then either lock tite the adjustables or order customs. The corners of the block will vary unless you have the block squared off so guessing is futile. Using stock spec pushrods is fine for stock rebuilds however for a modified engine get custom length rods.
