My 11/1 367 runs 207* at the stat-house and a 7# cap. This combo, with a 223/230/110 cam, went 12.9@106 with 3.55s and at 3650 pounds. That's about 335hp.
And with a Final-Drive ratio of 3.55 x.71od x.78 od= 1.97, got 32 mpg on a certain day-trip.
In 1999, I replaced all the hoses except the lower one. I have no idea in what year the bottom rad-hose was new.
If your cooling system is designed right ........ this is not a problem. She ran that way for about a decade and a half or more.
