Make it bigger, sell the unknown parts or use them as conversation pieces 4.300 stroke crankshaft, 6.535 rods, custom pistons, actual compression up 13.0 to 1 to but not over the fuel level for the compression your going to use IE race gas 12.5, Methanol 15 to 1 and so on Have a cam ground to meet your goals for ET and weight

Will a stock block last with that sort of power ?. I would sell the short block or keep it as a spare and build something aftermarket to meet your goals. JMO Mick

Keep the heads that way they are now and shift it at or below 7000 RPM, deadly bracket combination that will go faster than what you have now

You have a nice looking car, that runs pretty good numbers now, just have the heads ported and fit a bit bigger cam, that will probably pick you up another 3/10. Mick

I have most of the part to make a 511CID you can have the pistons noched for a good valve relief and be almost there. I'll send you the parts for $1300.00 Shipped Crankshaft - 440 Source 4.250" stroke for a 400 block Rods - Eagle 6.535" w/L19 bolts good to 1500HP Pistons - Icon forged 4.375" bore (w/stock valve reliefs) The pistons can be notched for the B-1 valve reliefs. You would still have a pretty good budget left for the small things.

IMHO, the shortblock is basically un-sellable as you describe it, at least to me anyways, unless your willing to virtually give it away. You've got good heads as is, Id personally spend a bit more than the amount you'd hoped and build a big shortblock with an aftermarket block that will last a long long time at 800+, then worry about having the heads ported/more cam in a year or 3 if necessary... If it goes mid-bottom 9's with a 540' or 572' with stockish B1's and a mild cam I bet you'll reap the benefits of easier maintenance, and room for growth in the future. But I always tend to build for the future, much more than the present.
11.48 @ 120 with a 1.80 60' 318, stock 1.88 heads, stock 904, Pump Gas, 13 lbs of boost.

...if they are still in good shape resue the current piston and go to a 4.25 stroke and new rod anbd have that solved...If those pistons are good that will save you some $$
I agree. I also think with the masses either opt for the -1's or MW Victors and sell the B1 origs. Gotta consider headers into your budget too, these more common heads use common headers. This will achieve your first expressed goal power-wise. I'm not so sure about meeting your budget though.

If you trust the block, you could build a 512 to go with the B1 heads which should give you the lightest bob weight. Ideal situation is a center counter weight crank with the RB mains, machine the block to fit. That will let the block live longer. Then when it is time you can upgrade to a low deck after market block (KB?)with the same dimensions. That should give you a torque peak around 6200 rpm and allow a shift point at or below 7200 rpm to help with the life of the motor. Converter will need to be loose enough to flash to 6500 in bad air, to make it consistent if you plan on bracket racing. No matter which way you go, the budget will have to increase IMHO. If you choose to stay with a MW port head, it limits you to around 8.80 at 3,000 lbs under IDEAL circumstances. What ever you chose, be sure the way you go will have room to grow to your ultimate goal years down the road. My goal was to be able to run super comp, but the heads and weight of the car don't allow me to get competitive. If I set up the chassis to cut a light, I don't have the Hp to go 8.90 in the heat. If I set up the chassis for best ET, reaction times suffer and my lights will be poor. So the long term game plan is pretty important! Maybe a post on your ultimate goal for the long term is in order, or we could look that over here.

Option two, with new pistons , bowl and valve job to wake up the heads, and at least 499 cubes. Best deal is 512 4.375 bore 4.25 stroke. My suggestion of a center counter weight crank is only if you can swing it someway cheap. New cranks done that way are not cheap, but a great addition if you can find one used. B1KEN ran a 511/b1 low deck combo(not a special crank as i recall) for years, in supergas with good results. Look up his fastest car ET, i think he was running low eights in a light car. Found it-
8.178@ 167.12, 1.139 60', B1 Ken, '88 T-Bird, 2430#, 511 B-1 w/ Glide

How important is a girdle and half fill on the 400 blocks (at/around the 800 HP level)?

Well filling the block is great provided it HAS NOT beenmachined already. IMO it is a very good idea to ad some stability to the bores. Some of these block can be really thin on the thrusts. The girdle, iMO is debatable. Dont think it will hurt much but not sure how much they halp. I have run low decks with decent power and just done a couple of things. One is aluminum caps and rods. Next keep the bobweight as light as you can, how light well that depends on application. Lastly keep the thing from detonating and it will give you many years of happy service at 800+- hp.. Oh yeah let the flaming begin Oh yeah an aftermarket block does not necessarily mean no cap walk...Been there done that, ask Greg I think he will concur.

I've been around Geckers low deck B1 builds for forever, and all he used was aluminum caps with studs..
Trust me, He abuses his stuff..
His last 521" made 900hp+ @ 7300, and was still climbing.
400 block filled, aluminum caps, aluminum rods..
As I said before, 4.390 x 4.310 = 521"..

I dont mind getting a 4.310 crank, but unless I'm making a big mistake, I'd like to save a few bucks and re-use my existing 4.375 pistons.. if possible
