I think a 700-800 horse stock block is gonna be a time bomb but there are guys getting away with it with a stud girdle and aluminum main caps. My last 2 400 motors went 6.20's with around 650 HP at 3050 and 3200 pounds, one was a 451 and one was a 500. I used the 400 block and aluminum caps, no girdle. The 3050 pound car had Eddy heads and a 590 purpleshaft cam. The 3200 pound car had older 440-1 heads(329 cfm) and a roller cam. Both were pretty much pump gas motors.
Very intresting u run that fast,Im getting ready to get mine to the track, 383,with indy heads,and a 4.25 stroke crank and have been wondering what kinda times it will run, u r starting to scare me LOL

I built a 400 into a 500" stroker. was lucky and started with the '71 400 block. Added BCR aluminum caps and stud girdle. No block fill (street car). I think the cost of the engine block, main caps, stud girdle kit, and machining to fit the main caps and girdle was about $1,500. This could have gone towards a race block, but I'm on a budget too. Being on a budget I used the 440 source 500 stroker kit, flat top pistons, with the longer 6.76" rods which is one of the lightest bobweight kits so it should not stress the block as much as the longer stroke, shorter rod, heavier 512" kit. I have chassis dynoed the engine to 7000+ RPM, but with my mild cam I usually shift under 6,500 RPM at the track. Rear wheel HP was around 560 HP in full street trim. I would guess easy 650+ at the crank? Engine is using Edelbrock Max wedge Victor heads, and an INDY 4150 flange intake, and 1,000 cfm HP carb. I think the carb may be a bit too small for the engine? The one issue of using a 400 block is there is not as large selection of intake manifolds compared to the 440 block.

I'd do the 4.25" arm with "440" mains in a 400 block using alloy caps. 512"ish with a MW port area in an SR or EZ head because your choice for rockers is cheaper if you decide to put a gentle roller in it. There is a Duster for sale out of Florida (green) in these classifieds you can pattern your build after or even just buy the car.

Not was wide or as tall (hood) as a RB block. Also I feel the cylinders and main webs are a little less likely to crack on the 400 blocks.
The above is true and why I feel the 400 is the better/safer Block to build.

LOL, the first big block I ever put together everyone predicted a 10,20 and I laughed. But first day out it went 10.73 and a couple months later went 10.20!
A mild 451 with 11.5 compression at around 3100 pounds with good Eddy heads and a cheap cam like the 590 will flat out run! Mine had a tunnel ram and a big hood scoop so the 500" Indy headed roller motor in the 69 Dart made a little more power but I love the cheap 451/470 motors with solid flat tappet cams and Eddy type heads.
