540in small block
 

this thing runs in a jet sprint boat do they go that big in the U.S

WOW you got any links to who builds this thing????

the bigest ihave heard of is just under 500ci but thats on a LS2 using a deck plate!

Chris.

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.

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

they say in artical speacial one off billet super tall deck block proaction 11*heads totaly unrecognisible in its current guise,heres the site tecnical says 500in read on and he says 540 based on small block quiet cool i thought www.pcrjetsprinting.com

Doesnt The Donovan Block go up to 600?
iv read somewere that it does,could be one of those Hiwayman :D
