Question Dart Lil M block, does it have 350 or 400 mains?

Guys,
Just a quick question,
Are the Dart Lil M blocks available with either one or do they come with one or the other? If so, which one?
Thanks so much,
Donnie

31131211 9.025" Deck/4.125" Bore/350 Mains Steel Caps
31132211 9.025" Deck/4.125" Bore/400 Mains Steel Caps
I think I have those part #s right. I dont sell the Blocks so Im not sure but they do list it with the 400 bore and either a 350 main or a 400 main.

We sell the Dart Little-M blocks with 350 or 400 main with Nodular Iron or billelt main caps.

Steel Main Caps Vs. Cast

Like Carl says, they come both ways. Probably better off with smaller mains.
As for steel vs. cast caps, this is just our opinion so far working with 1/2 dozen these particular blocks. We feel it's a total waste of time and money for the "steel" cap option. Let me explain. Staying on this platform, 9.025" "short" deck you are extremely limited to the overall internal components you can "fit" inside, stroke, rod length, compression ratio, cam dimensions, etc. Unless you're building on a Turbo/Blown platform, the nodular caps will perform fine. You'd probably end up breaking internal components before these caps. If you want a serious unit you go right to a "Rocket" block or something similar and get the cam out of the way. Trying to build a "big-inch" (480"+) SB with a relatively low-compression ratio, with a fairly large cam, is slightly difficult due to piston design (dish, pin-height, valve notches), etc. For these, we don't even consider the 9.025" units. Thanks, Gary in N.Y.
P.S. We've sold a few of these, but these 6 we'll be building. The first one finished, (my own, a 406"), is bolted up and ready to go, and gets tested tonight. The Dart blocks (and both G.M. and World's) are however worth approx. 20 HP over conventional castings. But this has nothing to do with the caps. This info is aimed at SB's only.

And all this time I thought that "Lil M" was a rapper. I guess now somebody's gonna tell me that the "Big M" I read about isn't the bouncer at Baby Dolls but some kinda engine part as well. And I suppose "Merlin" isn't a magician either, huh? Dang, just when you think you have it figured out...
