Hey guys.
I, too, like 59chevy36, have a 1957 235. I put HD 30W in the Blue Funk at the last oil change. Seems to me that it takes a little longer after startup for the guage to go up to 30 (original guage). It'll also sometimes drop down to about 15 when idling. I kinda wondered if things had truly changed or if it was just my perception.
