Could also be the pilot bushing in the rear of the crank that the input shaft centers in.

I think anything in the trans that vibrates like that would make a ton of bearing or gear noise, there just isn't room in the geartrain inside the case for things to wobble enough to make a vibration without tearing the heck out of things inside it.

Time to pull it out...

You relayed earlier the same sentiment that most all of us have... Like to build your own so you know what you got.... I would go through it and find out. Cheap enough, because it's fresh... I'd pull it down and check everything, rod length and weight bottom/top. Everything. Any luck you won't have to spend money beyond gaskets and balance work.

I pulled a fresh Windsor down earlier this year that had a mild vibration.. Had standard recessed dish<(cast) all but one, which was a dish with different volume.
So I bought a set of forged slugs and while waiting for them to come in checked the rods... plus minus 9 or 10 grams all over, not to mention that much of the extra weight was mostly on one end of two of the rods.

Balance fixtures are cheaper than they use to be. I bet it's in your crank more than the rods. Also pulled one down once which was missing a pilot bearing, similar vibration... Either way you'll find out when it comes down... Don't be mad......... you know it in your gut...

New issue. Might have something to do with vibration. Went for a drive after my Seahawks got stomped . Motor did not like the way I drove and developed a nice tick. pulled valve covers and have a loose rocker arm. Looked farther and the rocker is already bottomed out. Could only get 1/2 turn more. Pulled the rocker and you can see where the arm is starting to wear into the stud nut. All rockers are the same as far as no room to tighten down rockers any farther . Also noticed distributor is on the firewall. I ordered longer pushrods. I will pound on the firewall a little when I change pushrods. My hope is doing these two things might solve the vibration. Interesting that some machine shops don't understand you can't go wit h stock pushrod length all the time. Lifter looks fine and rocker arm has the right travel. I don't think the cam is flat. I will find out for sure when the new longer pushrods are in.

If you don't mind post a pic of the rocker in question, I would like to see the wear pattern. And the distributer shouldn't be hitting the fire wall, Not so much that you would have to hammer it in JMO. What distributer did you say you had in it anyway. Got me thinking someone might have moved the engine back just alittle.

You won't be able to see the wear with a picture.. I can just barely see it myself. They are comp cams roller tip rockers. #1412-16 from Summit. It is an HEI distrbutor. We had to smack the firewall in my friends 67 Firebird when we put a 350 chev with HEI into it.
