If you use Eagle rods it's a guarantee you'll have to get the block filled due to the rod bolt profile. Use Compstars and with a competent builder you won't have any trouble with clearancing the pan rail.

As said above, spend the extra cash and get the compstar stroker rods. I have them in mine and required no block fill, can run stock base circle cam. These rods require the least amount of clearencing in the block and come with arp 2000 bolts.

With a 6" rod and NO2 I would be looking at a 383, besides the already addressed poor choice in Eagle rods.

Run this pan and you don't need to clearance your stock one.

Milodon part #30909

That pan cleared my motor just resting on the block without a gasket on it. I spun the motor over by hand and it never hit.

If you run a good I-beam rod, chances are it will clear with minimal fuss. I-beams clear much easier than H-beams do. You can find a set of I-beams that can handle serious power for around $500.

Impossible!

Just you wait, lol. I'm sure the Eagle bashers (that have never owned anything Eagle) will chime in with plenty of INTERNET links and hearsay.

No one said anything about the quality of the rod and whether or not it can be run with a 3.875 stroke. As a comparison my builder put my Eagle rods and the Compstars I just bought side by side and the rod bolts on the Eagles were .100" taller that difference can mean whether or not you break into a water jacket when clearancing.

I reckon since you finally got your turd started you are no longer on quiet time, eh?

And speaking of "INTERNET links..." are you still going to plug Clayton Racing as intense as you did w/out ever owning their product?

I've used Eagle rods in two of my 396's (including my current one) without any issues or having to fill the block. However, I would probably use a different rod if I was starting from scratch. The Oliver rods have a pretty low profile "big end" which allows for not havin to remove as much material from the block. In my opinion, if you have to fill your block at this level, the engine has not been properly built. 2% of the "street cars" may require it, but certianly not at the common level of build that your setup is.

Yea man I have an Eagle 396 rotating assembly as well, on a daily driver. To the people complaining about eagle rods, it is usually the bolts that are the weak link. The L19 bolts are very strong but the bolt heads are so big that clearancing is a problem. If you go with the ARP2000 bolts it is much easier to clearance.

If your machinist is grinding the bottom of the cylinder walls by hand and doesn't do that kind of work often they can hit the water easily.

The bottom line is that many people that have stuffed 4 in cranks in an LT1, it can be done.

It has run all year. Was down for 3 days to swap motor.

I will plug their quality of work anytime anyone wants some feedback. The engine looked great and has zero issues. If someone wants a quality built motor and has no care in the world when it will be finished, they are the shop to go to.

You suck at trying to stir the pot, btw. It's funny how you always post in the shootout threads but you don't have the means to attend, lol.

I understand that. Just looking at your Sig I questioned that. Things like a dedicated fuel system, different trans, converter etc....there is a big dollar commitment to set up a car to handle that. I personally would go with better internals taking that kind of hit.

Oh I can always count on some bat **** crazy response from you.
That's the spirit, though. Plug a shop that takes almost a year to do a short block and lemmings everywhere will believe that is the norm, you trend setter you!

Right. I would suggest keeping it a bit simpler. IMO you'll be happy enough with a built engine that can handle a 150-200 shot.
