Moving a Car with NO EXHAUST MANIFOLDS

Got my stock F.E. exhaust manifolds out for a Jet Hot coating.

Now find I have to move the car.

Can I fire the engine with no manifolds at all to move the car 60 feet or so. Worried about the cold air getting to the valves too quick and possible warping something.

I"ll push it if necessay BUT I"m lazy !

Whats the general concisus?

I believe damaging the exhaust valves is an old myth, Look at the exhaust stacks on a P 51 for example.
That exhaust might as well exit directly from the block. Towing with a rider is feasible if you are still concerned.

run it

I don't think 60 feet will harm anything. In high school a friend bought a four door hardtop 66 LTD with a 390. He liked the sound of open headers like the older fast guys had but of course had no money. He pulled the exhaust manifolds off anyway in anticipation of getting headers and of course broke off most of the upper bolts, Even if he had headers there would be no way to attach them.... so he drove it, for months, with no exhaust manifolds whatsoever. Sure it did wreck the engine eventually or perhaps it was the frequent 6500+ rpm blasts in first gear at highway speed that wrecked it.

The cool part (besides the many police stops) was it made flames out the ports! Woohooo, just like Don Garlits.

Heck I drove my 66 XL for about 5 miles, with one side missing, no problem what so ever, of course it was in Vegas, and it was probably 90 that day

What, maybe 20 second?

The block won't even heat up in the time it takes to travel 60 feet!

Frankly I would be more concerned about the exhaust flames/heat setting wiring or something else on fire.

And that was the motivation behind my reply....

All kinds of wiring, hoses, lines, etc., right in the way of those exhaust ports and you will get flames out of them.

Will it burn a valve? I've always heard that it may. I personally wouldn't take the chance over 60 feet.

That's my concern as well

Any backfire or open flame can quickly ignite any fuel- like a minor leak, flooded carb or dirty oily insulation- and its downhill from there. It doesn't always happen and I've seen a number of vehicles started like this or moved with no problems. I've also seen one go up in flames in a instant. Not cool.

Have a fire extinguisher (btw- it took me four to put out that bike and my friend holding it....) ready if you're going to try it. My vote is for pushing or towing it.
