Bore increase I'm having my block bored to 355, and I'm looking into some forged pistons. I'm on a budget, so I'm hoping someone knows a good deal. I'd like to pay around $300, although I know $400 is probably more realistic.

These Speed Pro pistons are about as inexpensive as you are going to get at $289 through Summit

These Keith Black ones would be next in line at $329

Yeah you gave him exactly what he asked for. I just tried to say he was not taking a step forward as I am sure he would like too.
I am so tired of seeing all these slow "built" motor cars and this is one of the mistakes that leads too it.
As I have said before, it is not cheap to improve on what the factory gave us.

Since when? The factory LT1 is decent, nothing exotic. Go spray a stock LT1 with a 150 shot. You'll get a summer out of it. Go install a 4-5psi blower on one, you'll get a summer out of it. I know of several cast crank 383's with h-beams and forged pistons that don't break the bank, and can handle some serious boost or juice. And they were relatively cheap. $1000-$1100 for the internals.

Forged piston> hypereucraptic all day long , no two ways about it. The guys on a budget there will be some compromises made.

N2O can be safe, you just have to have your setup made to accommodate it.

With the budget forged pistons you are taking a step back and a step forward at the same time.
Step back - thicker rings which could cause more wear and will have more drag than the thin metric stock rings. Both wear and power loss would be minimal IMO.
Step forward - stronger pistons that will stand up to more nitrous
You would probably be better off to run a quality set of hypereutectic pistons with the metric rings if you don't plan to use a whole lot of nitrous. Good hyper pistons will take some abuse. The stock ones themselves are pretty good.

Do any of you guys have any first-hand evidence of this "thicker ring pack wear" that "could" occur or is it just internet banter?
Oh, and as for nitrous I should have just said a 200 shot in my first post. The point I was trying to make is that LT1's are a decent motor, nothing exotic, nothing substantial, nothing really out of the ordinary, just a solid 350 sbc with a few quirks. Yes they can be rebuilt for pretty cheap unlike what the taxi driver says.
