new build need advice

building a new motor with some restrictions. not looking to set the world on fire. heads are tfs streets flow numbers int .100-73 .200-156 .300-226 .400-291 .500-331 .600-345 .700-358 .800-377 exh .100-57 .200-112 .300 154 .400-192 .500-212 .600-236 .700-248 .800-260 questions are with these flow numbers were does the ci become a mute point. mechincal flat tappet cam only no hyd or solid roller. must run off 93 octane gas. would like to stay with a 4150 base style carb because we have the tfs intake already would change to a 4500 if its a deal breaker. want to make a honest 750hp. as always any input is appreciated.
Thanks,
Steve

no one has any thoughts on this.

you will start with a solid foundation such as a 4 bolt block   you will have years of enjoyment out of it with out fear of it coming apart.

If you're looking for that kind of hp on 93 better build it big as you can.

using the last one of my dove-a boss bulkhead blocks is one of the reasons for limiting the hp to 750. will use a steel crank not cast no matter what the ci ends up being. I tend to use heavier rods and pistons and not spin them as hard for reliability prefer scat crank and scat h-beam rods. I guess what i'm trying to say is I will spend the money for the better parts and not run the motor on the ragged edge all the time for relibilty and longevity. however you spell it!!
Thanks,

730 hp here on a d3 block. Over 100 passes and I dog the hell out of it. Next will be an aftermarket block. I'll have to find some money though.

will the heads in original post flow enough to get the job done on a 557 ?

My 552 with a429cj heads is making close to what you are looking for but I am turning mine 7000 and it has 14.7 cr
