As long as you have good oil pressure, the only good reason to freshen it would be leakage past the rings or valves/stems. As long as it passes compression and/or leakdown tests and isn't blowing oil...

Unless you flatten a lobe on a flat tappet cam. The teardown/cleaing/repairs/new bearings will outweigh the cost of going with roller the first time by a good bit. If it's a mild build, you don't...

Other than tall decks, that's the only Mark IV block that was only fitted with 4-bolt caps. All others can be either 2 or 4 bolt.

If it's the original engine in your '81, you won't even have to spend the coin to upgrade it to handle more power.
The 4L80E is a hoss, handles big blocks without issue. It's a lot more...

If you go the route of using the longer stroke crank, buy one made for the application. If you have an old 400 crank, you'll have to pay to have mains cut down .2 and you'll probably need to turn...

Pump piss, we usually get 85 - 87 octane. Factory tune, haven't done a thing to it. I've never run anything in it other than the lowest octane available at the pump.

Do a lot of research before you pull the trigger on that engine. ProComp junk heads in particular. 360cfm heads aren't anything to write home about.

Put a damned wrench on it and give it a try. If it gets harder to turn, you're turning it the wrong way.

That crank - as long as you get the one that can be internally balanced - will handle just about all you can throw at it short of large doses of nitrous. A guy over at the Team Chevelle site ran one...

Clearance should be built into the piston. If you have a block honed at 4.030, the piston should fit the bore with perfect clearance. If you go with KB Hypers, you'll need to pay particular...

Smart decision, IMHO.

From my limited experience, worn or damaged cam bearings are #1 culprit of low oil pressure.

And 9 out of 10 of those will get a new oil pump and the owner will be...

Groove wasn't worn by a rubber seal.
It was etched by dirt and grit on the outside of the seal.
I've never heard that it was machined there on purpose. Ever.

Built correctly with good machine work, they're no different than any other engine built the same way. Since you'll be making more power, it will take a bit more to cool.

I'd probably run it until you're ready with the other mill. A good bit of the metal will already be embedded in the bearings and most of the rest is in the filter. Since it still has good oil...
