I just got my engine back from the machine shop (lm7 bored to ls1 specs) what thermostat should I run? It’s never going to see boost or nitrous. Just a daily driver engine with 243’s and. A very small 216/220 114 lsa cam.

 

Stock. Quicker warm up

 

Beat me to it! Its been proven that stock temp usually works the best

 

Cool, thanks guys
