I recently built my gen1 350 using summit heads and found they were manufactured with 3/8 npt ports for temp senders. My truck has a oem temp gauge which requires a sender that is 1/2 npt. Summit no help, their supplier no help. I do not wish to to re-tap the hole and am hoping someone else might have found an alternative temp sender would appreciate any assistance.
