400 stock block...cast N crank 1800 HP

WOW No room for error in build or tune to do that. Incredible...

I'm going to guess, you pushed cast crank near 7800-8000RPM???

My 1-2 shift was 8100 RPM and the 2-3 shift was 8400 RPM, trying to go through the lights at 8600 RPM on those 7.0 and 6.9 runs last year.

OMG!!! Thanks for the inspiration... StockBlocksTTFMF.

With turbos I shouldnt have to turn anywhere near that RPM with the right heads and intercooler. My 59 block certainly has more beef than any 400 I've seen... And turbo's do tend to be easier on parts... I doubt I'll have a car that could use that power... but I'd still like to build the motor...never know when someone comes along with the right car for it. Meanwhile it can be run with the wick turned down and still be fun knowing the reserve is there.

Mark, you paying attention???

It makes me feel better about choosing forged over billet, that's for sure.
