If you already have it all sorted out, why do YOU not just do it already!

How do you think that a higher deck would make for any larger clearance inside the crankcase for more stroke? Have you ever even seen a TD BBC? Or ANY BBC?? Only if the stroke was to the extent that a pin couldn't be fit to a piston would the deck height come into it. The physical dimensions inside the engines are identical AFA clearance for counterweights and rod to rail or cam clearance goes.

Do you have any clue for what it takes to run a 427 @ 8KRPM, reliably? More to the point, do you have a clue, period??

FWIW the IHRA P/S "Mountain Motors"- 900- PLUS cid- turn just a tiny bit more than 5.5K RPM- reliably. How about 2070 HP @ 8100. 932cid. NA. Carbureted.
