426 hemi block 2468330-M

What can anyone tell me about this block? How far can they be bored? How much stroke can you put in one without too much trouble? Looking to build a blower motor with this block and some MP stage 5 heads. Any help would be appreciated!

Ok cool, it is in a running car now straight up 426, small hydralic flat tappet cam and a MP cross ram intake.

Can it be bored much more than .030" or .060" from where it is now?

How much stroke can I put in it without too much trouble?

I would like to at least get to 500 cubic inch.

Anyone make shelf blower pistons for a Hemi?

Unless it was a unbored siamse block(not likely probally) it won't take much more than a stock street hemi block will on the bore size, 4320 max usualy I built one of those blocks that was 4,180 unbored, I had it sonic tested and decided to bore it to 4.25 and leave at that. I used a 4.375 stroke blower crankshaft with counterweights to use with the 10:71 Littlefield blower, Stage V heads and two 1050 blower Domintor carbs. that combination made 925 HP at 7300 RPM with 7 lbs of boost on CA pump gas several years back

That combo sounds pretty close to how I see this project turning out, thanks for your input.
