FWIW and for those who may not have known I had a 511" low deck B1 motor that went 9.0's at 3470lbs all motor with no issues, well other than the block not being real happy. Did break a cam as well but feces occurs. This was a good 400 block, had to buy and sonic check 7 to find a good one. It was filled, tall fill, had aluminum caps and I made an effort to keep the bobweight as low as possible. It worked well for what it was but not going to spend that kind of money again searching for a good block and the paying to have that one machined. I just dont need all the stuff lying around anymore. I do still have two good(sonic checked)230 blocks left though.

No problems, but of course they would work better w/ a bigger bore but for OOTB on a 400 low deck, IMO, they kick ass... The OOTB Brodix deal comes w/ SS valves, Manley Nextek springs (good for up to .800 lift), etc....we utilized a .740" roller in our motor. Rotating assembly was nothing special....Eagle Crank, Manley Rods, JE Pistons w/ basic 1/16 ring pack, etc. We used custom made billet main caps to get rid of the spacers on the girdle, this made the caps flush with girdle.....dont know if it helped but sounds good  IIRC, we did the entire motor for under $8K

If you want the answer from someone who has done more of these combos than anyone..IMO.. Call Scott Koffel.. The stuff Gecker has used..and is still using is stock 400 blocks. I've known him for 25+ years and he has always used the low decks...Except when he had Hemis..  *NOTE* When Gecker had some catastrophic engine failures, it was always with the Hemi...  rotating weight.. I've seen the 452" and 471" B1's go over 8500 rpm well over 600 runs a year when Gecker used to race on the National circuit. He is still using a 400 block now in the dragster, making over 930hp.  Yes, he has broke a few in his day, but has many, many runs on them. So ask Koffel what they do to these things to make them last..  Chris..

Or you can spend 1500 bucks more and use the right stuff. Running over oil or cranks isn't on my bucket list.

That combo may likely last longer in a dragster than a heavy street car. Just like an 8 3/4..takes alot more grunting to move a 2 ton than a 1 ton. 
How do you figure this?
Were not talking 8 3/4 rears LOL
The engine doesnt know what its in, or cares for that matter.
Its just common sense. If the crank is working harder to turn the shaft there will be more flexing... and thats what tears those blocks up.
In this scenario, both cars would have the same gearing and trans. The lighter car runs faster because the motor is doing less "work" to move it. The motor is subject to the laws of physics just like you or I. Thats all I'm saying.

Ten years ago I had the chance to buy a 540 inch, low deck aluminum kb motor with B1mc heads that made over 1000 hp , and would push a local 2550 lb 9.90 car to 170 mph on the throttle stop! I am sorry I didn't figure out how to come up with the $$, and that same package appeals to me today. If you already have B1 heads, why not treat them to a block that will let them roar?
sounds like "Twist and Shout" leftovers.....
Paul split quite a few stock blocks before going KB.

You guy's all crack me up You can spend 20-30 grand or even more on your ride, but can't spend $1500 or a little more, for a good safe block. Think on the safty side of it. Only if 440source would of made a block, right? But now they are having problems with the water pump housing they sell.

Sorry My common sense must be broken
How does it work harder, and make more stress?
If the engine makes 800 hp, and you shift it a 7K in car A weighs 3800 lbs.
Car be weighs 2000 lbs. The engine still makes 800hp, and the torque and power range doesnt change, so you shift it again at 7K
Explain to me in lamens terms how it works harder to achieve the same power level?
Were not looking at E/T time slips here, acceleration, 60 ft times...No increments.
How does the engine live longer in the lighter car?
If this were true they would never blow up on the dyno. The engine see's the load and tries to move it.
I have had some in depth college Physics classes, i dont see how weight of a vehicle or chassis setup can effect engine longevity.
Just a friendly debate here..
IMO vehicle size has nothing to due with the stability of a engine. Things like bearing clearance, and bore thickness, detonation does however.
Just think about what your trying to say.
If told you the weight of a vehicle in theory has little to do with max top end speed given a perfectly flat surface you would also think I am
