i have used scat and eagle crankshafts and i have found the journal tolerance much closer on the scat cranks,from an assembler,s viewpoint i like the scat better because of this.

I don't get it either. Reason I purchased a Dan Olson 14 quart offshore pan that I will only run 12 quarts in.

Unless you heard it straight from callies that they intend/plan on discontinuing oversees products, I highly doubt it. How many people building sub 1,000hp motors can justify a $1,500 crank? Our economy won't support that, so if they opt to change their business in that way, GOOD LUCK. It's a world economy and the Chinese have been casting/forging longer than anyone. I'm not denying some of their stuff is subpar, however quite a bit of their 4340 is quality. It's the machining that leaves a lot to be desired. Just because it's made in EEEEEMERICA, doesn't mean it's of quality. Plenty of lazy slobs producing crap in this country and the consumer is blinded by the waving flag sticker.

To update this: While speaking with callies this morning for the second time, it was confirmed they are discontinuing the Compstar I Beam rods, seeing that for around $150 more you can get a USA rod, so it makes sense. They stated that "Compstar is here to stay". Take it for what it's worth I guess. Also stated that they DO NOT have any issues with L-19's and that if it were an issue they would either 1. Supply latex gloves 2. Go away from such a bolt if it had all these supposed issues.

Confirmed it twice with callies who uses the L-19 in all of their BBC rods in this series. Oh the Internet....

Well, seeing the thread about the rod bolts makes me want to set up a 4900 RPM rev limiter for my 4.25 stroker with the Eagle crank and rods and the 8740 rod bolts. At least I went through the trouble of using a stretch gauge on them. ;)

Lol. If callies backs it that's the final word in my book. My machinist also does quite a few circle track and marine engines and he laughed when the topic arose. If the 2000 series were the appropriate bolt, callies would utilize it in their BBC rods. As assumed, the L-19 is a better bolt.

Good choice stretching the bolts. I never use to do this, however a guy I know that owns Forrester Racing engines here in Arizona converted me.

It was interesting that ARP suggested 63 ft lbs with their lube if using a torque wrench, but to get the stretch figure they called for I had to go considerably higher than that. I called them about it because I was concerned, but they told me not to worry about it and to go by the stretch figure rather than the torque. They used a conservative torque figure to try to keep people from overstretching their rod bolts with improper procedures and old yard sale torque wrenches that had not been calibrated since the dawn of man.

How many have actually seen a rod bolt fail? I know we don't use them in a marine deal but in an aluminum rod deal you just have aluminum threads supporting the whole rod. I think it's really a waste of a good argument really.

Probably not that common, but I have to wonder if some of the spun bearings are actually from rod bolts stretching and starting to fail, which could lead to lack of crush on the bearing. Which could lead to a spun bearing.

You're fine. I'd have no problem using that rod/bolt combo with 800HP all day. Your typical H beam rating for a BBC is

800HP with 8740 bolts
1200HP with ARP2000
1500HP with L19

I take that with a grain of salt though, because there are things like stroke, piston weight, rpm, that factor in. But generally speaking, for a N/A 496 Stroker, you have PLENTY of connecting rod with the 8740 bolt. However, if I was building a 1500HP engine, I wouldn't be using a eagle, scat, or compstar rod. I'd want some Carillos in there.

Manley has been providing H beam rods for many years. I believe they recently dropped the L19 option from their h beam rods. Now you can only get 8740 or, upgrade to the 2000 series. If you get their pro series rods, they come with arp2000 standard, and ARP Custom Age 625 as an option on certain bbc rods, such as the beefy marine duty I beam rod that cost 1500+ a set.

:Thanks MT, I appreciate the input. Of course, I also have the limitation of a cast steel crank instead of forged, but this is far from a max effort build. If I had the whole thing to do over again, I certainly would have gone forged from the outset, but for what I will be doing with this motor, I should be fine.

Planning to hear it roar to life this weekend! :ernaehrung004:

BTW, is that girl in your avitar surfing OSO? ;)
