Adam,
i read that with a 800 roller cam your combo is good for 850 hp and 1000 hp and 725TQ are easily possible

lower comp motors with 700 rollers about 800hp and 700ish tq
but it did mention using O ringed copper head gaskets with nitrous use or compression over 14:1

Steve , don't need the block O ringed till around 14:1 or untill DC predicts (IVC) , only running 9:2 so will be good for the MSL gaskets , DC is around 8:1 , so a good safe combo , will also be a peach to tune for the sniff.

While I had the camera out, thought I would snap one of the new aluminium flywheel/flex plate to replace the Heavy JW Wheel.

4.625, isnt that the absolute limit on that block Adam ?

Mark, Mick .....
4.5 x 4.500 = 572

4.5 x 4.625 = 588

4.5 x 4,750 = 604

My motor is square bore & stroke (4 1/2" x 4 1/2") = 572ci

Adams Bore is 4.562" with 4 5/8" Crank = 604.6725185370001 to be precise or 9.9 Litres if you prefer
