You could make this a 434ci if you wanted to, I'd be weary of 1.110" CH piston that a 434ci would use at 1500+ hp.
This combination uses a Wiseco piston with 1.140" CH that in other customer builds has been run up to 1950hp. Piston has extra top ring land.
434ci, same price, 423ci, stronger.

$550 gives you block and heads machined for 1/2" head studs, I have some options for the head studs themselves, ARP 8740 steel $400 for head studs, ARP 2000 steel stud kit $600.
RHS block includes rear cover
The heads at 70cc be 9.0:1 compression, can mill the heads and up the compression.
We can machine the block for Jesel belt drive $275, otherwise we do offer RHS timing cover for $175.
You can have the block machined for Belt drive and continue to use a timing chain provided you install an external oil pump. The level of performance for this engine, external wet sump is commonly used.
