I don't think the Big Bore alone created those gains. If I'm not mistaken he has FR500 heads and intake and aftermarket cams. While there's no doubt big bore is going to help, it won't provide gains like that on a stock or bolt on car (if that is what you're trying to imply, not really sure). And NAZ is not a part of modular depot. He lives in Germany. I do believe they assembled his motor though.
He had the FR500 equipment before his Big Bore shortblock. I think everything else was the same, maybe he added a JLT as well, not sure.
there is as many info threads on here as any other web site that has been on-line for the past year. :thumb:
