i need a better 400 sbc block

--------------------------------------------------------------------------------

i have a 406 with pro 1 heads, i'm putten a 4340 steel crank & rods, forged flat tops, with a solid roller cam. i was told the other day that when i put the nitrous to it, the bottom end will give out. so i'm looking for a block that can take 800 hp. i'm pushing around 525 without the nitrous, & planning on shooting a 250 shot of n2o. my 4 bolt block, as i'm told won't take that kind of power, & a 2 bolt with splayed caps wouldn't be much better. so i need a block that can handle 800 hp.

where can i look for a new non-bowtie 400 block? i did a search & couldn't find anything.

which block is better, the dart lil m, or the motown?

what are my options


help me please

I think both those blocks are good, i am running a 358 with a dart lil M block and I like it alot. I have never had any problems with it running up to a 300 shot, the motor is 600 hp by its self. I would recommend dart but only because I have one, and have had no problems with it. The World block could be just as good.
The main difference between the dart lil M and the dart iron eagle that I know of is that the iron eagle has a raised cam for a stroker setup. If it was me, and you have not yet bought the rotating assembly, I would go with at 434 kit and a iron eagle block, you shouldent end up spending a whole lot more money, and you will gain some stroke.

I dont see why you 400 4 bolt main block would'nt hold up to it. Maybe you should try main cap straps?

Have you considered using a progressive nitrous system?

there isn't enough metaL in the main webbing area. straps would reinforce the cap, but not the block.
