Looking for an aluminum BBC block that can handle 2000hp and a 4.600 bore. Don't really want to spend the money for a billet deal looking for info from anyone who has run something similar. We have a donovan right now and it isn't holding up that well. The sleeves are moving and just not getting decent ring seal.

We have a Keith black KB700. Bad ass block. Cross bolted mains, raised cam . Head studs go to the bottom of block and
pull from there. Webbing like you wouldn't believe. I will post pictures in the am. Ken Black says he rates them at 5000 HP. Awesome guy to deal with . $5200 . 10.500 deck . When u see the pictures u will believe .

I run this block http://www.newcenturyperformance.com/Blocks.htm with a 4.60 bore and I'm very pleased. Bore's stay round (ran same rings for two seasons) and Lowell is a jewel to work with. Block price comes with all the fixtures.

I talked to Lowell the other day but wanted to hear from someone who runs his stuff. Everything he told me sounded great almost to good. Are you running a step sleeve set up and are your running water in it. We are running a blow through deal on gas no intercooler and are making about 1850 to 1900 right now and the donovan block isn't holding up like I would like.

Yes, I'm running a stepped sleeve. Yes I'm running a water block on gas blow thru at 2000+hp. And raised cam.
Several guys I run with run one also with zero issues.
Not one issue for me, and everything Lowell is saying is true. Best deal out there for what you get over all.
The KB and New Century are pretty much the same.

yes, jeff johnson sells a pan, because the crank is up in the block with cross bolted mains it is a shallow pan.....the one in the picture is a wet sump regular oil pump style...very strong well thought out design for strength !!! really is a work of art...and yes if i remember right the head studs came with it....the one in the picture is a 10.500 deck...raised cam and spread rails.. big block ford cam journals.....the 4 3/4 crank falls in there !! call ken black...awesome guy...very straight forward guy !!

The New Century comes with head studs, pan studs (includes gasket) and if memory serves me right...timing cover studs also. There included in the price.

Also comes with screw in freeze plugs on water blocks.

I had Dan Olson (actually his son) make me a pan for it. I was very impressed with there work and price.

The KB and New Century are almost identical. Both nice. New century probably better to work with. The sleeves get pretty thin at 4.600 bore. I have a CN billet block tried to run 4.600, two passes busted two sleeves. This was more than 2000 hp, probably 3000, 60 lbs of boost. Went back to 4.500

New Century blocks are very niece pieces for sure . Maybe look into 1/2" head studs if possible , never to much clamping force . At least 904 lifters is a good idea also .
