:hail: I want one

Can u imagine the sleeper effect with that 454 if u changed out the valve covers that stated plain as day what u had under ur hood.
:hail:

 

You'd never see it coming! You would really need a good setup to keep it on the ground.
and it runs on pump gas...
Gonna need allot more tires too!

 

It's been out for a year or two...I considered this before deciding on a BBC swap, but after talking to them, I decided a BBC is a better way to get those cubes.
Basically, what they said is, the motor is going to be OK if used NA only, no spray or boost. With spray or boost, its going to have head gasket problems. The bores are just too close together, not much meat left between them to hold a gasket...
other than that, its probably not bad...

 

yeah, but.......$10,000 bucks?????????


that price is "insane".......man, i'd get the ZZ502 wayyy before i'd pay ten grand for a 454 "small block" even though it says it made 550 hp at 5,000 rpms.......10 grand is an absolute "ton" of cash for this deal


-bigarmzz-

 

screw that, check this out if you want a big inch small-block.

Shafiroff 434 SBC

or this

Shafiroff 472 SBC

 

$11,700????

hell, i'll take three of those



-bigarmzz-

 

All I have to do now is win the lottery!

 

im lookig into the billmichell 427 sbc or the Shafiroff 434 sbc. yes its alot of money but it is so worth it. they come already broken in,dyno tuned with dyno sheet, and they thave a 2year 24,000 mile warrenty.

 

I have spoken to those guys about this engine, and it's true as tommyt says, that it's a NA engine ONLY.

So it's kinda maxed out, and thats abit of a shame considering the block otherwise have handled 1500hp+ on numerous buildups and track proven.

THe good thing about this, is the 427. It has the same block, crank, cam and evrything else, but is a "unbored" block at a stock sbc 4.125 bore! It won't have any head gasket problems, come with the same warranty, and cost a bit less.

It still has 530 hp though, a can safly handle a blower or some N2O. At least that's what they said to me. And can still be bored up to 4.250 if required at a later stage.

I'm saving up for their 427 shortblock, I might be there sometime a year or so from now.

 

The Shafiroff 434cid SBC gets my vote also, but with blower friendly compression ratio and different camshaft. Only need to save up the $11000 now!

 

Geez, flame me if you want but with almost 600HP for a street/strip small block, do you really need a blower or nitrous?
I'm also from the more is better school but I think there's enough there to break rears and trannys several times over.
I'd keep it simple,
I do agree the Shafiroff 434 is a nicer bet for the longhaul.

 

there is a guy on this board his name is Baddest305 he put the 434 in his 91 camaro and he's running 10.3 the last time i saw him run. he old 305 he had only got him to i think it was mid to high 11's

 

that engine isn't anywhere near maxed out, you can always go bigger. Bigger heads, bigger cam, bigger intake and carb....just depends on how radical you want to go. And just because it is listed as N/A, doesn't mean you can get them to drop in some low compression pistons and a blower friendly camshaft when they build it.

 

It's true it isn't maxed out when talking about hp level, But it is maxed out in what in can take of cylinder pressure, thats what they told me. They did NOT reccomend it as a basis for a turbo buildup or heavy nitrous.

Of course you can have them put in lower compression pistons and a turbo camshaft, but if it where me, I'd take their word for it when they say that the gasket won't hold it.

 

the reason for the high cylinder pressures is the combination of the compression and the cam, not the engine itself. Of course if you want to run boost you're going to have to run different gaskets, if not even o-ring the block in heads. Running low compression pistons and a blower cam will solve the cylinder pressure "problem." I'm sure they meant it wasn't a good basis for blower or nitrous "as built" as they list it on their site.

 

No, they meant it was a bad choice because the block don't have enough meat left between the cylinders to o-ring the block. There isn't any other gasket availiable either for this bore, the one that exsist is specially made for this block.

My point here was that if one wants to run big boost or spray at a later stage, one is better off starting with a WP engine with a smaller bore, on that permits o-ringing, gasket choices and much higher cylinder pressures, like the 421, 427, and maybe even the 434.

Thats what world product's sales represenative said, and I belive him after seing that siamesed head gasket.

 

ok, well that makes more sense then.


guess thats why they build the engines and I dont
