I never thought anything of it. New pump (stock flow from summit), stat, radiator, sensors, hoses, clamps. The works. Stock fan tho. Car is on a Holley terminator X with an MFKustoms adapter so it’s using the stock sensors. Gage on the cluster also rises as expected. It has a 195 stat. Now after a few light pulls on a hot day it’s sitting at 222 just cruising. I’ve burped the system, can’t seem to get any more air out of it. Hi and low fans work, I can test them with the Holley and they are set low fan : on 208 off 202. Hi fan : on 216 off 210. They work as expected. All of the cooling shroud is still in place. Is there a secret to burping these that I’m missing. I don’t know of a bleeder or anything. I have friends with the same setup on a Holley and they barely break into the 200. Should I get a lower stat?</blockquote>
