biggest ive seen so far is 488 using a dart tall deck block.

thats got to be a bbc,i dont know where you would get a block for it,we build alot of 475's for dirt late model,a 540 damn.the biggest bore a sbc block will take is 4.300.

That looks like a BB to me.

[Sales@Dutchboys]

I cant believe that.

[pist0lpete]

Thats crazy. I know that the new Warhawk LSX blocks are supposed to increase the Cubic Inch potential of the small block but not to that level I don't think.

looks like 2 different set ups to me, the 1st pics looks to be a split intake runner BBC, and the 2nd pic is a SBC

Doesnt The Donovan Block go up to 600?

[rocketman]

on the site he said its a one off block.

the biggest donavon sbc block is 4.300.with a 400.raised cam and 9.8 something deck hieght.

for a 540 sbc it doesnt make much hp.only made 700hp,it said on the site.

we build 1000+ hp 468 sbc

[hiwayman]
