So I finally got the new temp gauge installed along with my oil pressure and tach. My question is, what should the normal temperature be for my 289 that is bored .030, has performer intake with holley 600 carb? I also have headers if that makes any difference. I do not have a fan shroud and I don't know how many core radiator I have, but I think it's like 17"x20", i'm pretty sure it's not stock. When I drove her yesterday for about 20 min into town at 60-75mph the temp got up to around 220*. I don't think it should be that high. I havent had to sit in any traffic yet so I'm not too sure how hot it'd get if I were idling in traffic. What should be a good temp for my engine? Now what would be a good oil pressure for my engine? When I start it up it goes to about 40-60psi then after driving it for a bit it drops down to like 30-40psi. But then yesterday after driving into town and sitting at a stoplight I looked down and it was below 20psi, but after I drove off it raised back up. What should my oil pressure be?
