Technical Just curious about a Dart 5.2 block

I’m not in the market at all for a small block 427, etc. but a buddy sent me a link earlier today about a “Dart 5.2 427” engine.
Googling yielded no results, Darts site had nothing I could find.

What the heck is the “5.2” referencing?
I’m thinking a version of the block?

 

"5.2" may possibly be deck height

 

Hmnn, SBC is 9.025? Maybe dart looks at a different measurement?

 

Bore centers?

 

I’ve not a clue! Lol. Wait, @DDDenny has a small block 427, but don’t know if it’s a Dart block?

 

Rodeck.

 

Well dang, you’re no help.
I may wear out Google tonight.
Thanks for that!

 

Reminds me of what June Cleaver said....."you were a little rough on the beaver Ward".

Not sure if this helps

 

That was the link my friend send me. I was trying to figure out what the “5.2” references, nothing there that I could find.

 

This might be it? STAGE 5.2?

Yes, that’s the engine I’m asking about. But what I’m asking is what does the “5.2” refer to.
As
I mentioned I’m just curious, no thoughts of having/needing one.

 

It's just Skip White's designation for this particular build combination. He has several levels of performance engines, changing cams, compression ratio's, heads, or strength of rotating ***embly parts.
The "5.2" is not any number ***ociated or ***igned by Dart, and doesn't refer to any dimension on the block.

The link you were sent just happens to be "Version 5.2"

For example....
Here's a Dart block destroker, 377 cubes, "Version 2.3"
CHEVY TURN KEY SBC 377 STAGE 2.3 DART BLOCK, CRATE MOTOR 530 hp | Skip White Performance - We have the best prices you will ever find for aluminum heads, rotating ***emblies and strokers

434", now "Version 5.5"
CHEVY TURN KEY 434 STAGE 5.5 DART BLOCK AFR HEADS CRATE MOTOR 632hp-SERPENTINE K1 | Skip White Performance - We have the best prices you will ever find for aluminum heads, rotating ***emblies and strokers

 

Well okay, I guess that explains it. Thanks ericnova72. I was curious too.

 

We’ve been running a Dart sportsman block in our circle track car for years. Started as a 377” and now a 422”. I would not build a racing engine without one of the aftermarket blocks and maybe not a street engine either. The bore can be 4.185” and a 4” crank (you figure it out) will fit eventho we use a 3-7/8”. The best this is EVERYTHING is off the shelf. **** and CP/Carillo have everything covered. Today any style cylinder head you can think of is offered and so are sportsman shaft rocker arms…..

 

Thanks for that . I will be able to sleep better now. Lol.
