Run the stock crank and do a 355 with forged pistons/rods and ARP main studs. Or go with forged crank and do the 383 with the same stuff.
I would also consider doing the 4 bolt, forged everything, and run a h beam instead of i beam rod.

Here is the same motor with the forged crank:

Thats a $1000 difference. Thats why I'm going with the cast crank.
Studded 2-bolt would be another way to save money but still have adequate strength.

FWIW I have also seen a Eagle cast crank go 10.50s on a 225 rwhp shot a bunch of time and is still running.... its a 383 with a stalled th350

Thats the chance you take if you go cast man. If you want to gamble 2000 bucks that the cast wont break then go right ahead and buy it. No one on here is your Momma or your Pappa. For a grand more you get a piece of mind and you have a platform that you can build on down the road even if you have 100k miles on it. With cast you are limited to N/A only and the silent killer of these cranks isn't horse power in the end it's TORQUE. and thats what a 383 is all about. A Cast crank in a 383 has been a NO NO for more than 30 years. I hung around a lot of engine shops in north GA when I was young and I can't tell you how many times guys would come in trying to keep cost down on an engine and the builders would tell them to go find another builder. Today engine guys don't really care that much because they know you will be back looking for another and thats money in their pocket. You would be better of having them build you a 355 with a stock crank and then doing a AI or LE top end either now or down the road. Then you can at least spray it or do light boost on it. stock cranks have been good to 600 where as most guys that push anything close to or just over 500 on the cast stuff end up BLOWED UP. research the different types. Stocks are nodular iron. if you read into it and understand what cast is V's the Nodular iron you will think twice. Some of these guys have learned the hard way or shall we say the expensive way.
Just this summer someone posted pictures of the metallic gravel they ended up with from a cast aftermarket crank failure. Such a thing is likely to do damage to a LOT more than the crank, will lose a couple rods at least and head damage is even likely. There are folks who have ended up with nothing left in good shape but the intake.
A turned crank will run you $125 -$150
new bearings $85ish
gaskets $125-$150
1 day for assembly. Save your coin for later when you can build the bottom end EXACTLY how you want to.
If you need a single replacement rod/piston to replace a spun bearing rod speak up, a number of us have them laying around. I know a few times I have sold a rod/piston combo for like $25 shipped, not to make a buck but to help someone get their car back on the road cheap.
