I guess I dropped my 383 small block bare block off at the machineshop early in the spring. I told the foreman there was no hurry as I wouldn't be racing this season.

Well he took that to heart !

I stopped by to talk pistons and he and the owner said they are going to start on the machine work next. They have the sleeves in stock and we talked about ordering parts.

Might have it together by spring...

A 383 is a big block unless it's a Chevy or some configuration of a small block Mopar I've not heard of. Which is WAY more than possible. LOL
 
I held a little service with my half-built block today. Sat there and drank a beer, while I waited for it to finish assembling itself. Needless to say, I was disappointed in the results... :eek:

383 Short block...? Or maybe a .060 over 340 with a weird 3.63 stroke crank.....Naaah.
 
Oh come on fellas, for now, lets just call the B block the small block vs the RB... at least that’s what I assumed he was saying

When you say "I am in no hurry", a machinist hears " I don't have the money to pay you yet".

I disagree. I tell my machinist that too... mostly cause he does my stuff on the side. I paid a 30 pack of bud light to have my 452’s milled. He told me I was really good at spending money. He must not have met my wife... I figure most of the time, you send the motor to the machine shop before the rest of the car is done. I know my motor has been done for 2yrs machine and 1 yr short block. No need to put the heads on if it won’t be fired for a while. My car won’t even be in paint til the fall
 
It's a small block 360 .030 over with a 3.79 crank.

I could have had it done by June if I had needed it. Just getting a few sleeves, flatten the decks and honed.

He built this back in the 90's for the PO. Since I need a few new pistons they were hoping another old customer would have some spares from one of his old engines but I guess not. So we're going with a new set. This shop built quite a few dirt super stocks with Mopars back then.

My buddy had a 340 at his favorite shop for 3 1/2 years!!! I told him not to pay for it until it's done but he gave the guy $2g's upfront...yikes!

386.7 cubes if a guy wants to get technical. Should be fun.

Well, maybe I should have said that is how I hear it. That is why I quit taking in work. Having several thousand dollars worth of work sitting in my way waiting to be picked up, while wondering if I'd be able to pay the electric bill.

I'm with Toolmanmike.

(4.03/2)^2 * π * 3.79 * 8 = 386.7489743. But who's counting...

Mopowers has it.

It's 387 CID because if it's anything over 386.000 it rounds up. Always has.

If an app or something says something else, the something else is wrong.
 
I figure... 3.14x8x4.030x3.79...

My calculator sez 383.yada yada yada.

383 just sounds more Mopar-ish.
 
Oh no... a 383 stroker.. lol most common small block Chevy!

The 3.79 strokers make a great engine. I want to build one some day.
 
I just say I'll pay you when you are done, how long is the warranty or guarantee? showing a handful of cabbage helps.

Not sure where that formula came from, but I'm saying dealing with NHRA in Como eliminator and some CID restricted circle jerk stuff, that won't fly. You are off enough to not fit the rules.

Bore X Bore X Stroke X .7854 X the number of cylinders. Right out of the NHRA rule book.

I've seen guys get burned by this before and it's not fun to watch someone lose a race of even a National Record because the math isn't correct.

So here is your math.

4.030 X 4.030 X 3.79 X .7854 = 48.343734 X 8 = 386.74987

That means you engine is 387 inches. I usually go out one more digit on the bore. But ghats close enough for this.

4 cubic inches over what you think is a big deal for the powers that be and write the rules.

In your case, it's just semantics, but everyone should know the actual simple formula to calculate CID so you know what you have.

Must have taught me wrong in school... The margin of error with an abacus was pretty wide.
 
Local track has a 410ci rule but it seems one guys 410 is a lot bigger than the other guys. Anytime someone can gain a full straight lead in two laps tells you his math is as bad as mine.

At least he assembles his own engines unlike most of the competition.
