Can anybody tell me if this is a good setup. I'm just looking for another opinion. I kind of think I'd like to go with a 750 carb, would that give me more HP.

Thanks for all your honest opinions. I get that not every engine from those places are bad or they wouldn't be in business.
From personal experience, a 230/236 cam in a 383 is not beyond what power brakes will support as long as you run a dual plane intake. That's the cam that Blueprint uses. In a 350, that would be too much, but in a 383 it is not. I think you'd be just fine with vacuum assisted brakes. I ran a 355 SBC with a 225/234 Isky roller cam and it was fine with vacuum assisted brakes in a '72 Camaro.
I hear what you're saying about checking valves and rechecking heads...that's lawyer speak though. Adjusting valves and re-torquing head bolts isn't a big deal when you're talking about a $2000 price difference. Thats literally turning some bolts and checking clearances which would take no more than an hour. That's real money but not much time. I just can't imagine spending $9K on a ho-hum 383 SBC. If you want to stick with your local builder, I'd ask for a cast crank, pistons, and PM rods to save some money as forged pieces at that power level are not necessary. I'd also tell him to use the AFR Enforcer heads. Those Liberty heads are not a good deal for the money.
Back to your point, I don't think what your local builder is any better than what you can get in a crate motor at all. Building an SBC is rocket science and if he tries to tell you that you need forged pistons, rods, and crank...that's just BS. At 450HP a cast crank, good rods, and hypereutectic pistons are fine. Keep in mind that GM used hypereutectic pistons even in the LS7 which would blow the doors off of anything with a mild 383 like this.
the bigger the cubic inches the more camshaft you can have before vacuum is an issue. my good friend just installed the 500 hp 396 blueprint small block and his brakes work great.

My experience has been 14" of vacuum is about the least you can have & the vacuum booster still function & then a vacuum tank may be of help of course that's with something larger than a 7" booster.Dual 8 or 9" or a 11".If you really want good brakes pitch the vacuum booster & go Hydro boost then all the camshaft you want.
