Four bolt mains

Being splade they look like they are strong and go into the meat of the rail. One problem with standard 4 bolt caps is you need a T/A, X block, Resto / R3 to use them. One thing I did run into when using a Milodon pan is we had to bulge the pan to fit. with the standard program 4 bolt mains. I would use those caps if I had them. Make sure that you have them installed in a bed mill and then line bore and rehone the cylinders with them torqued and torque plates on both head surfaces .

Yes , that is something else , So much more beefy than a std 340 block .

Ahh,, There they are . Thank you very much. Those mains look both sturdy and weird , To be tightened the right way or disaster. Cheesus.

yep, all the little side spacers have to go in the right place as they were all machined for that spot.
don't ls chevy motors have crossbolted mains too?
neil.
Years back I over tightened a oil pan on this 67 GT 500 428. Broke 3 inches of the pan rail off. The cheapest most expensive hunk of metal junk I ever owned. Not only was it a pig it squeaked like an old bed spring going down the road.

light rods and pistons help more than those splaied wanna be mains
girdle is a lot to do on a block that is weaker than needed at high power levels

Ford did side oiler
we spent a lot of effort to copy and feed the mains from the side

I was gonna say the same. You beat me to it. Also, the little Chevy LS motors have 6 bolt mains. 4 bolt conventional AND side bolted too.

works great
you just grove the block main bore from the oil hole over to the parting line and drill a hole in the bearing
to be better it would appear to be down the cap some but nothings perfect
you are trying to get the oil in where it's needed for hydrodynamic wedge
there are pictures on where the sweet spot is for inline engines
not so much for v8's and IMHO the sweet spot moves around depending on which bank is firing
so I take the inline data and apply it to both banks
you cut down on the big oil hemorage at the bearing feed in the center of the block
crank is being pushed down (mostly) but the clerance actually moves around

Sorry just off track but they are a good pan I run one on my stroker only down side you need to lift the passenger rear a little bit to get all the oil out due to all the trap doors.

You are correcting oil timing when you do that. That's going to piss off all the ding dongs, doubters, skeptics, nattering nabobs and general fools who thing oil timing to the rods isn't a thing.
But it be a thang for sure.

Don't care about all that , I was referring to why did they not go over big. Was limited production and still couldn`t neat the hemi cars--------

They won le mans with a side oiler
Basic Ford head problem even with the tunnel ports but bottom end was solid and heavy
Mickey Thompson solved the head problem- Hemi heads and the cammer
Mopar bottomeend was heavy too, longer rods and lighter pistons help but hemi dome is hard to get light
Mickey's hemi heads (Top Eliminator at NHRA NAtionals on a Pontiac) were designed so they could be drilled for most of the 4 head bolts per cylinder heads
olds, cad pontiac, ford FE Chrysler
not all were ever made but design was there
