Sorry to hear of your trouble whittp. Seems another link bar roller retrofit bites the dust. I am pointing this out because there are guys posting these lifters are trouble free which they are not. Far from it actually and these lifters are expensive to boot so not sure the juice is worth the squeeze.

I would like to thank Jim Hand for banging the 041 on a 1.65:1 rocker arm drum to avoid all the problems we are now seeing. I bet the farm Pontiac engineers would have never used or approved the link-bar retro-fits for use in a production setting because of the warranty nightmare it would have caused.

Jim didn't sell you parts and knows what he is talking about.

Same here HIS. If you never drive it I'd go roller as it cool to say you have a roller motor even know the bearings are not.

Always wanted a BMW

Roller bearings are one of the reasons Germany lost WWII. Tanks do not need roller crank bearings, but they had them. Cost,time=lose.

OP, first thing you need to do is cut your oil filter apart and see what you have going on.

Roller bearings lost the war. Nope.

That was not what I was trying to say. The Germans had a habit and still do of making things over complicated when it was not needed to get the job done.
Made equipment hard to produce, time consuming and expensive.
We won the war because we simply out produced them. Their Panzer tanks were far superior to our Shermans but we made 50,000 of them !!
They call that POS Sherman Ronson,s because they lit the first hit, every time.
Operating a Sherman in WWII was horrible duty.

Ball bearings - we bombed their ball bearing plants and this was a part of what ended the war, shortage of ball bearings.

Yep, Bremen for one. We lost a lot of guys in those daylight bombing raids of that damn city.

The M4 vs the Pershing- lot of differing opinions on that one. One being why in the world did we keep trying to prop up the M4 instead of going all out on getting the Pershing into the war earlier.

Crower still making good stuff. I was able to get my set of Pontiac Sportsman rods at "close out" special in July but it took some time to get them. They are sweet looking for certain and well balanced.

This may help on that subject:

It is a 68 400 block with an eagle rotating assembly. Cubic inches are 461 with this set up. The crank is also going to have to be replaced due to the thrust bearing and I figured I'd go with the eagle forged crank. Connecting rods and pistons are all in good shape.

This thing is a mess inside and I'd sure like to not repeat this again. Hoping the TKX will solve the issue on the crank getting pushed around (and be a lot more fun to drive). Now I'm worrying about the reliability of the top end as well. What can the shop do to ensure it'll be good the next go round? They did mention that most of the prior build was done well but a few corners were cut. Rings not exactly right, bottom end not balanced, #3 was burning a little oil and it's probably the valve seal.

Sometimes builds go that way with some shops. I've had fairly fresh builds in here that were running okay, but when I tore them down and took them to Paul for a going over, all kinds of things were found to be "subpar" even for a mild street build. It was a matter of time before things went south, and just lucky very few miles were put on.

Hate to hear it and very unfortunate for you, but maybe the shop you're at now will do a thorough job and straighten things out.
