I would think he's using corn oil, it's whats the rave is all about these days isn't it?

[IsaacHayes]

I've switched back to all natural.

But I think Jon is using mobil 1 ?

[pocket-rocket]

Those bottom end bearings sure do look good. What sort of oil are you using?

[robertisaar]

You should become a doctor, you sure do have patients!

that was a james bond level pun!

[1988GTU]

50 bux for bearings, and maybe a couple bills for a lower end balance... vs adding another 500+ for slugs and 200+ for rods... HRMMM... wanna contribute to my go fast fund... I don't think its large enough. LOL

I still think the stock lower end components should hold up fine.

Forged stuff is coming in a few years when I can afford to build an entire second motor.

If you are going that far..... new slugs, shot peened rods, and full balance. You know you cannot resist!

Just dropped some cash today...

Got the Clevite perfect circle TM-77 main and rod bearings, and the Clevite Perfect Circle AL-3 cam bearings for a 350. I also got a new PTFT rear main and a timing cover set.

I'm debating on getting a lower intake bolt set, and a new oil pan gasket...

I figured for under 50bux it was worth replacing the main's and rod bearings since I'm in there and they are all coming out anyways. I'm also debating getting the bottom end balanced...

Dave, have you pulled the cam yet to look at your cam bearings?

Not yet, I will before the engine goes back together though. might be another month or so..

[geldartb]

i was wondering about the heavy duty version. guess you just solved my question.

looks like ill be getting the heavy duty version.

Jon how long did your stock ones last with the new cam or did you initially start out with the swapped bearings.

[3400-95-Modified]

I found out that standard duty bearings are part number SH-290S those are the same babbitt type material as stock 60* bearings, BUT the other number listed is SH-1349S which is the Al-3 material, (Aluminum) for Heavy Duty application.

here's the info

[geldartb]

that's what i was trying to find out with the cam bearings and got no answer in the other thread.
just trying to find out what everyone who was using them was using for brand and what year/years they used to buy them.

i might pull mine apart to check stuff. it still looked good when i sealed it up a few months back but id like to check the cam bearings. still got a few months left till im gonna drive it.

[3400-95-Modified]

I just sent him a PM asking him that... As well as what part number he used.

[3400-95-Modified]

I'm half tempted to replace all the bearings with Clevite's just to be sure they will last. Granted my lower end looks beautiful, but Better safe that sorry?

These are the part numbers I have... PLEASE chime in if I'm way off here.

Cam bearings
SH1349S Material: AL-3

Rod Bearings
CB1238P Material: TM-77
or
CB1238A Material: AL-5

Main Bearings
MS2037P Material: TM-77
or
MS2037A Material: AL-5 (Cant seem to find standard size though)

Which do you guys recommend? the Aluminum ones? or the TriMetal for the rod and crank? I'm already definitely planning on going with the AL-3 cam ones since the babbitt Sealed power ones I've used have BOTH now shown signs of being over stressed.
