So I got the TTI headers in my 74 Charger. Rear end 3.23 with sure grip. Everything was fine around 40-50 mph during initial break inn. First time on highway it didn't take it long to peg on the H side. Wish I had a gauge to tell the exact temp but never seen the car run near this hot.
Lower hose collapse or radiator flow doesn't make sense since neither was a problem before the headers. Are the extra RPM's requiring more water flow? The radiator is new but a cheap Duralast B509 from Autozone. I should get a quality radiator in the car. What's everyone running in a big block for a radiator? The Griffin 5-70070 says it's an exact fit don't really want to spend 800 on a radiator. Would a high flow water pump make sense? Can runs cool in town, only gets hot at highway speeds. Thanks for any input.
