I'm also using the 7lb cap with an original radiator recored with a staggered
tube/louvered fin core, a water pump from Patrick's, and a 160F thermo. The
freshly rebuilt 261 runs at about 170F.
What's pretty hot? When I broke in the cam on the 261, it probably burned a
little hot at first (less than 190F), but has settled down to the 170F. Once
the engine is broke in, I'll probably switch to the 185F thermo. Good luck!

<< I finally got my 57 235 in my 41 3/4T running last night.Seemed to run
pretty hot. I've got a 180 thermostat, using 41 3/4t radiator (just
back from radiator shop) , using Jack Carter's shortened shaft water
pump.
Question is: Original 216 installed used a non-pressure radiator cap,
should 235 be using a pressurized cap with ?? rating?? Is thermostat
too hot?? any opinions??
Would appreciate any advice!!
TIA

I use a 7lb cap, and a 160 Tstat in my '59 - 235, if that's any help for
you, never had a problem with it running hotter than 170-175, even pulling
Donner Summit in the summer time, loaded with about 800-900lbs of truck
parts. RPM's between 2800-2900 in 4th gear.
