The Manton Series 5 will take way more abuse, lack of lubrication at high RPM, than any of the Smith Bros or any of the other comparable priced brands will Been there , done that OP, is the Trend brand a true one piece pushrod If so are yours for pushrod oiling or are they solid like the stock OEM Mopars are ?
I did go with the trends 7/16 dual taper .165 wall. the price delivered for 18 pieces was $350.00. If I'm not mistaken, Manton was about $150.00 more. I always do thing backwards, buy first and ask questions later. I guess I wanted to make sure I didn't go the wrong way.
