Hi!
After many months of work to stuff a 300 Cubic Inch Buick V8 in a 1977 MGB
Roadster, I finally started the beast a few days ago and everything seems to
be O.K. except for cooling. The engine seems to run a little hot or maybe I
just don't have enough air going through the radiator or something! After
about ten minutes of initial run-in at 2000 RPM the temp crept up to 220 and
probably would have gone up more if I hadn't shut it off. The radiator is a
Davis aluminum cross-flow (19 X 21), 160 degree Stant thermostat, 20 psi cap
and a small (13") mechanical flex-fan which is shrouded. Timing is set at 34
degrees total advance at 3500 RPM. RV8 headers through the fender well. I'm
using an aftermarket mechanical temp gauge since I couldn't locate the wire to
the original gauge, so the accuracy is probably +/- ten degrees.
Has anyone out there had a similar experience with a new engine during initial
run-in? Suggestions?
Thanks in advance for you time in replying,
Doug Trichel
