Thinking out loud..

how big can it go? Yesterday i talked to a guy with a SB, 8/71 blower running only 5 psi boost because of the high static compression he has. He told me it´s a stock 340 block filled, then bored to 4.125", with a 4.125" crank = 441 cui. Car is running low 9s, it seems to hold together....at least for a while ;-)). He will upgrade the short block during the winter, then crank up the boost.

I´d never heard before about a stock block taken this far. Must be pretty thick....if i see him again this season i´ll ask again.
