I have a totally restored 1951 Chevy 2 door hardtop. 1964 Chevy 327 ,bored 30 over , powerglide trans and 3.55 chevy rear.
I bought it last fall 90% done with Fresh rebuilt motor ,trans and rear. Everything new or rebuilt top to bottom.
I have ran into numerous little problems all winter. But finally got it on the road last month.
Drove 10 miles to a shop and had #3 exhaust valve spring break . Friend had good used valve springs so for now we replaced #3 intake and exhaust valve springs .BUT then a week later I broke #1 intake valve spring so we replaced that .
Checked lash on all and adjusted . I'm going to replaced all valve springs but for now I needed fuel sender replaced and brakes fixed .
So had 140 miles on motor and made my longest drive ,37 miles to a friends garage since he has a lift. Replaced fuel sender and found bad master cylinder so those issues are fixed .
Drove the 37 miles at 60-65 with no problems . BUT
on way home (2 days later had to order master) I only got about 18 miles and engine got really hot ,oil pressure dropped (due to heat)wouldn't keep running .
I had friend come and tow me home . Once home it ran for 45 minutes in garage with no problem ,at idle.
I've driven it twice now and I can't go 2 miles without it getting hot and wanting to stall, runs rough, shakes.
We have checked thermostat, water pump, re-checked valve lash , antifreeze 50/50, headgasket good.
1964 ,327 , bored 30 over, RV cam ,headers edlebrock 600 carb,
Strange thing is I had 178 miles on it with NO problem. SO what happened while sitting in friends garage ???? Why did this problem start on way home ? After 170 miles ??/
Any ideas

Do you have a mechanical fan or electric? How old is the radiator? Aftermarket or stock? Weird that it idles ok but heats up at speed. What transmission? If automatic maybe cooling lines or cooler interferring with air flow.

There's more detail on his issue in the 49-54 forum.
