warming up a 454

what rpms should i keep my engine at with aluminum heads while warming it up. I try to stay around 1000-1200 but i accidently hit 1900 the other day and was wondering if that could have screwed something up like blowing a head gasket doing that?

thanx

i dont think that would have hurt it

why are you warming the car up at 1000 RPM's.....?

Starting u a cold engine and reving up is the absolute worst thing you can do.

Let it idle for a few minutes untill you get some heat comming out of the heater, then rev it up some.

Technically once the oil pressure is up and all the warning lights are off we can begin driving moderatly, not haulin. I have an aluminum Northstar in an 96 Eldo and it may run 20-30 seconds after start before driving is begun. It has 90,000 miles on it and a tiny little amount of coolant seepage at the head/block surfaces is nothing at all for its lifetime. Certainly 1,900 RPM is not over revving it. Punching out 4 grand as soon as it catches in the morning is.

1900 won't hurt it at all. (Unless there is already something wrong with it).

I just start mine and let it idle till it's warmed up or until I am ready to go.

agreed, once oil has circulated throughout the engine it is really to drive and more warming up than that is just a waist of gas. The engine will warm up faster if it is driven anyway.

Even if you did rev the shit out of a cold engine a blown head gasket wouldn't be the result
