Default Bore .030 over, what else do I need?

I'm pretty newbish, so forgive me if this seems rather straight-forward, but...

I have an L98, and I found a local place that'll bore/hone for a reasonable price. My question is, I have them do it...

Do I NEED anything afterward?

And should I GET anything afterward?

Only thing away from stock right now is a Flowmaster catback.

Thanks for your help guys,
Joe

That could be a pretty extensive list. If budget allows, forged pistons, good rods, and a stroker crank would be a nice addition. Don't forget incedentals like bearings etc..

Things you need at a minimum.....

Main and rod bearings, pistons, rings, and gaskets immediately come to mind. Have your machine shop check the crank while you're at it. Chances are good depending on mileage that you may need to have it turned.

Like I said the list is extensive and I certainly didn't cover the gamut. What you get is going to depend on what it is exactly your looking for out of your engine.

Either that or you're just a little short on word this evening...





Edit: And apparently I am short on letters

Well, I'm short on knowledge, and being 5'3", a little short on vitamins it seems, so, we all fit in. ; )

I have rebuilt about a dozen engines over the years. I would recommend having the machine shop vat the block and check it out for any problems. Have the bore done, the crank checked, new cam bearing and freeze plugs put in.

You will need pistons/rings. Main/rod bearings. A new oil pump. A complete gasket set.

The type of pistons really depends on how you are going to use the car. If you are a normal driver, occational play with the gas pedal and let the tranny shift for you, then regular cast are just fine. If you dog it pretty often, the hyper (whatever) pistons are good on the street. If you plan to do some serious racing, then forged is the way to go.

Are you insinuating that might be rare for me?
Seriously, I thought he was only asking what was needed specifically to compensate for the overbore. And yes, we will need to know what his goals and intended end use(s) are. So you want more power? I think you're in the right forum....

At bare minimum you just need the .030 pistons and rings and a new gasket set (has anyone tried to put an engine back together with the old gaskets? :o)

aj1988's on the mark, though: if you've got the engine out already for the overbore, I'd think you'd be nuts not to have everything checked out and new bearings installed.

And I'm sure if you've got some extra money burning a hole in your pocket, the folks on the board could give you 1,001 suggestions to remedy that

No doubt. ; )

Well, heres the deal - the car right now is used a DD while I go to school. Once I get my degree, it's going to become my project car when I buy a newer corvette. I'd like it not so much to be a quarter-mile car, but an overall preformer. I'd like to be able to pull 11s in the quarter (at least) (when I'm done), and I'm going to go highend suspension/brakes, and track the car.

Before I graduate, I'm going with a superram, LT headers (probably hooker) and a 219 cam, which should get me into 12s and hold me over until I can put serious time and money into the motor.

I saw a local company did the overbore stuff and figured it'd be advantageous to do what I wanted to to the motor BEFORE I did everything else.
