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.

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
