This spring I built a brand new motor for the 66' to protect the K-code when thrashing about the track. I ran the motor very hard for three days at the Mid America meet with no problems other than some fuel delivery issues. The motor has never really idled the way I thought it should.

Just this weekend I upgraded a friends car by stripping his motor down to the shortblock and replacing the cam, lifters, rockers and heads with the exact same setup I have. His motor idles better than mine! What's the deal?

We'll after agonizing over it for several days I realized why I am now asking for the doofus award. I LEFT THE INTAKE MANIFOLD BOLTS LOOSE! I always toss the cork gaskets use a bead of silicone on the valley rail. I set the manifold in place and then let things "set" overnight. Problem is, I then put the motor in the car AND NEVER TIGHTENED THEM!

I ran the motor to 7000 rpm for three days at Hallet, no water leaks, no oil leaks and the only "symptom" was a slight "shudder" at idle.

They're tight now, the motor now responds to idle mixture adjustments and life is good.

?AM I A DOOFUS?

(If you've been keeping up,... I seem to be forgetting alot of things lately)

Glad it's running good now!

I did that to the bolts on a con rod once! When I was in high school, I had a 58 Rambler. I was putting new rod bearings in, just before dinner. After dinner I continued. When I started it up, knock, knock. Luckily the front cross member bolted in. It was a snap to correct, and yes, I used a new bearing!

Hey it was a funky looking car with those fins, what can I tell you. Besides I only paid $25.00 for the car.

A very lucky doofus at that. Long ago the legendary Dewayne didn't get the manifold back correctly on my 289, go water in two cylinders, broke a piston, cracked the block. That's why mine has a 302 in it now.

Dont' think of it as a Doofus. Think of it as a field test of the holding power of RTV under adverse conditions/forums/images/icons/tongue.gif!

You are indeed fortunate. The intake gasket started to leak in my Olds after about 15 passes down the 1/4 on a new engine and got plenty of antifreeze in my oil pan. After identifying the probable leak site and getting everything else checked just to make sure, I am just getting mine back together now. Another classic case of an "easy fix" taking several months to get done .........correctly.

You probably spoil lots of food in the fridge, too, cause you just can't seem to remember to snap the lid on the tupperware!
