[71chevelle406]

I have a 71 chevelle with a 406 ci small block. Eagle cast crank, Kb pistons, and studed main caps. The upper end consists of Dart pro 1 heads that have also been studed. Driving the car last dream cruise I overheated it to about 300. The car still runs and drives great. My question is what sould I do now. Some people have told me to put new rings, bearings, and get the heads milled. I have lots of mony in the engine and want to do whats best. Pleas give me any imput.

Thanks,

Tim

i`m confused here, if it still runs great, then what`s the point? at one time we over heated a chevy 307 to about 280 and it was okay afterwards, it ran fine for another year and a half and at that point it already had over 70,000 miles on it. do a compression check, if compression checks out good on all cylinders and there 10 psi of each other then the rings should be okay.
If it doesn`t use any oil, and it doesn`t loose coolant mysteriously or have any water in the oil, and it still has and holds good oil pressure, i`d say it`s okay and to keep driving it.

Sorry for the clarity issues. My question is if i drive the car after over heating is it gong to be harmful to the engine components? If so what should I do to correct the issue.

If you fixed whatever made it overheat, and it doesn't overheat anymore then it is fine.

We used to have a Emod car that ran at 310 every race, every week, for 52 weeks before it decided to split the block under the second main web. Never could get to run any cooler.
