Can I assume then Steve ( not questioning you just trying to learn ) that these are normal temperatures ? How high can the temperature go in that area without causing problems ? As you remember my engine is taken out .060 over and you know what has been done to it, with the engine done like this what should my temperatures be at, under more or less normal conditions with some WOT involved when I get the urge to play. What temperature should I be at when I am on the highway and cruising at about 3000 to 3500 RPMs. I am also going to install a tranny cooler when I get back from camp, don,t think this will help keep my rad temp down, but I really prefer to have a separate tranny cooler, what are your thoughts on this? TIA

How much timing do you think I should pull out of it Todd?

JOHN

I believe Alex runs his S/S motors at no more than 32*, and he's got dyno access

At least 4 degrees, 6 would be better. Windsors don't like or need much timing. I run mine at 34 degrees overall, but that's with quite a bit more cam, exotic heads, deep-breathing exhaust and a BIG carbuerator

When I had it at 12 - 13 degrees it would not run worth a crap, what would be the reason for this ?

Is your dist vac advanced?
If so, are you setting the timing with the advance hooked up or capped?

Vac advance, set capped

I bet that motor would love a set of good headers
Easier said than done, I understand. Opening up the exhaust would dramatically improve the motor's ability to evacuate spent heat energy much more effeciently though

Headers = no collector plates . I will do the trans cooler first, highest octane gas I can buy at the pump (94), put a proper guage on the car so I can actually read my temp instead of the stock guage, In will then see how the temp goes then take the timing down to 14 or 15 to start and see what happens. Any other suggestions you have would be greatly appreciated.

How often do they check?

They do random checks, but there are also people that turn you in. The worst thing is, if you are involved in an accident, even if it is not your fault and they find something on the car that is not suppose to be on it, they void your insurance and you have no coverage . I,m wondering if my exhaust manifolds are causing some of this problem because they do not flow enough, especially at higher RPMs. This 289 is basically a cast iron stove with those exhaust manifolds and stock intake manifold. Any thoughts on this angle ?

JOHN

I do not see anything wrong with 200, you are reading the metal temp, not water temp with the infared gun, and it is going to be somewhat higher. Did you shoot the upper radiator hose or the top of the radiator? This would give you the best indication of actual water temp. If the water temp is under 190 I would not be concerned. You can safely run 210 on the water with the proper antifreeze mixture.

I have always ran 14 - 16 inital timing with no problems, if I heard detonation I would drop the timing back 2 degrees at a time until the detonation went away.

If you cant use headers you may want to consider 351W or HiPo 289 manifolds. They are a little more free flowing than the "log" manifolds that you have.
