I;m still kinda new with the muscle car performance stuff and i wanted to know if all i needed to stroke an engine is a stroker kit? Or is there special machines envolved?

shouldn't need any machining unless you bore the block too. I have a 67 mustang with a 302 from a 68 and when I get the 347 stroker kit I'll have the machine shop bore the cylinders .030 over...so i guess i mean it's not necessary but probably a good idea.

How much does boring .030 over cost?

it'll vary from shop to shop and also depending on your existing hardware and application. I also don't really have a lot of experience with machining so I couldn't even give you a ball park figure but i'd venture a guess at a 3-4 hundred just for the machining.

Our shop charges $15 per cylinder to bore. But... You will need the block cleaned. We recommend thermal cleaning over chemical cleaning. It does a more thorough job, and is environmentally "friendly". We also charge an additional fee to use a deck plate when honing (can make the difference between a "good" engine and a GREAT one). This is typical of most shops, though our labor rates are a bit lower due to geographical location.
Also, there's a certain amount of clearancing required, to be certain the rods and crank don't interfere with the block. The above mentioned 347 has had "notches" cut in the bottom of the boers to clear the rod bolts.
If you're considering a kit for a Chevy, avoid the "cast" cranks. They flex way too much, and are a liability. I would recommend Eagle kits above all others. We install them regularly, and the quality is unsurpassed. Have many Pontiac versions making well over 500 horsepower for street applications.

I was thinking about getting a 350 and boreing it to a 383 and putting in a Stroker Kit. Hook it up to and TH350 with a B&M Tork Master 2400 torque Converter. The my Rear Ratios would probably be 3.71 or something. I still need to figure it out. Hows that sound to you guys. Im not even 100% sure about all this.

Not to nit-pick, just to clarify. The bore on a 383 "stroker" (redundant when talking about Chevy) is the same as a 350. That is, it begins life at 4". Most "kits" are designed for use in a used block, requiring boring. That would make it 383 CID, by boring it .030" over. The stroke increase is where the displacement increase comes from.

So your saying a 383 could just be a 383 without the stroker kit. It really doesnt matter? So say I wanted to put a Stroker Kit on a 350. It would be better to bore it out wouldnt it? Ive heard people say that thats what you should do. I dont know, I have no clue about this stuff. Where is your shop located Mr.?

What I'm saying is that there is no such thing as a Chevrolet 383 (as in factory produced). By definition, a 383, based on a 350, IS a "stroker". You cannot bore the 350 block far enough to get 383 CID with the 3.48" stroke. You MUST increase the stroke to get there, thus making it a "stroker". Like I said, just nit-picking a bit. We battle misconception and "myth and superstition" every day in this business. My purpose here is to educate the novice, as to the reality of specific engine combinations, and their origins. By making clear, some of the bench-racing vernacular that pops up from time to time, a person can make a better-educated decision about their project.
