Re: engines getting rebuilt...anything special i should do
Well, I stand corrected on the 383. My apologies if I offended anyone running that setup, it's just my buddy hasn't had much luck with it himself (cyl. head issue here, cooling issue there) seems it's been one thing after another for him. It's not even the fact that he's a knucklehead, he's very mechanically inclined, so i apologize if I came across that way in any way, shape, or form. Still, I shouldn't blindly blame it all on the build, that's not fair. Injuneer, you're def right about the 383 being perfectly capable of making that much power. It's just that it seems like the bigger you go (c.i. wise) the more you sacrifice mgg's. 383 is a beast of an engine to run at the track, no doubt about it. However, I got the impression from vangill that he's just interested in a weekend toy that he can drive anywhere he wants. My friend really only uses his car at the track anymore (it's got a cam, heads, bigger TB, true duals, LT's, and almost no interior from all the weight reduction he's done). Vangill could get good gains from a 355 and not sacrifice as many mpg's, that's all. It's his car though and he should do with it what he sees fit, just wanted to try and give a different perspective and maybe help him narrow his choice.
Your friends car, honestly, sounds like a build gone wrong. Not to mention a "cylinder head issue here, cooling issue there" has nothing to do with the displacement.
My 383 outperforms just about every other one I've seen with similar mods and I would not hesitate to drive it as it sits every day, hence a build gone right.

Re: engines getting rebuilt...anything special i should do
sry didnt mean to turn it like this
and i would have bout a crate engine but this guys giving me an unlimited warranty for 3 years, weve already drawn up paperwork. i bout the car to get it rebuilt, basically just as a project to restore, it was a good starting platform and had a rod knock, so the engine isnt geeting built bc i want it to be crazy performance wise but bc i want it to be reliable.
but its pretty much getting what ricardo said and the guy he quoted but just the hyper pistons.
ive just read a lot about the 383 and mainly wanted to know if they just did amazing things if built like that, but i kinda understand a little better now, its all just different platforms for different purposes.
thank you all for the help, it did help me learn a lot.

Re: engines getting rebuilt...anything special i should do
The reason for increasing the displacement is to feed the motor more fuel and air, so of course fuel economy is going to suffer, but not nearly as much as you might think. It's more of a function of the valve train and cylinder heads than it is the displacement. It is VERY possible to build a streetable 383 since the capacity to make a TON of torque is there - perfect for a DD.

Re: Ooops no offense
and raise you 
I'm not, but I would still place my confidence in a "local" shop type build over a lot of the crate motors on the market regardless of the warranty....which we do just because as is apparent in this thread, it is a selling point for some.

As far as your original question - You could smooth/blend some of the oil passages for the oil pump and maybe get rid of any casting flash that you see in the block, if you feel like doing some things yourself. Good luck with your rebuild.
