Does anyone here have a 454 small block in there 3rd gen.

 

I thought a 454 was a big block. There's a guy in Houston that's got a 454 in his T/A. I don't think he posts here though...

 

you can make a 454 small block. and no one that I know of has one. BADDEST305 has a 434 small block, but I don't think anyone has anything bigger.

 

Merlin Hardcore makes a 454 small block that gets 600 hp

 

i think there's a 472 small block out there now.....crazy huh???

 

yeah 472 is now the biggest, shafroff makes the engine. They use a hardcore 415 block and then bore and stroke it. I would just love to put one in my car and then throw a set of valve covers that say 350 on them , no one would be the wiser.

 

Guy I work with has a 454 SBC (Merlin Block I think) in a 78 Malibu. Runs high 9's in the quarter. Strip only trailer queen, but fast!!

 

It's not Shafroff. It's www.Shafiroff.com

You won't find it on their website though. For some reason it isn't on there. At least I can't find it.

 

Actually, you can bore and stroke a Motown 427 block (small block) and make 500 cubes. It's been done.

 

you wouldn't happen to know the bore/stroke combo on that would you?

 

This is the biggest SB I have seen in print from SpeedoMotive

481

 

Thats what I thought, I was under the impression 48x was the biggest you could get and still have a useable block.

 

with an engine like that you're limited to 18*/15* or SB2 heads if you want to get them enough air. 23* Small block heads are too small for a 454 ci IMO. you could make 600 HP with a 383 or 355 for much cheaper than a 454 SBC

 

guys, you could probably bore and stroke a small block all the way out to a 502, that doesn't mean it's a great idea. I find it hard to digest that 454 or 472 is gonna be able to take much mod's at all, or even not over heat stock as is. I'd be careful, generally anything over a 427 sb is not recommended.
