@8luggarage not at all, temperature 190 after 20 minutes on and off freeway, hot summer weather. I drilled out the block for the water pump bypass 5/16" hole 2 3/16" in the t-stat and a 5/8" bypass hose going to the intake...it might be overkill, but it runs cool.
Yeah, l did, basically the same set up you did. The motor runs good !!
Did you have any issue with the direction of the water pump rotation vs a factory vortec pump?
