Have an engine combination, one and only at this price.

423ci RHS 2000hp capable $9500
RHS 9.240" 6 bolt block
Callies Magnum crankshaft
Dyers 300M forged steel rods
Wiseco boost pistons -23cc dish
Tool Steel pins
GFX steel top ring set
Clevite bearings
Includes ARP 2000 series main studs

optional:
*1/2" head stud machining $550
*O ring block, R/Grove heads and Clark Copper head gaskets $500
*GRP 2000 aluminum rods, no extra charge

 

Can you put this in a C6 Z06? Wanting to boost but not worry about the LS7 shortblock.

 

Boy that motor would be perfect for my twin 76's. If I could just sell the 402 before it's gone.

 

Yes, however will need to order LS7 style magnum crankshaft, price stays same. I'd say 6 weeks for a custom callies forged crank.

What kind of FI setup you plan on running?

 

Is this motor assembled? what bore and stroke?

 

+1 Interested in this as compared to an lsx 434 ci.

 

^^^ RHS block is aluminium alloy much lighter then the iron LSX block

 

Yes, machined to blueprint, Crankshaft balanced, and assembled. 3.900" crankshaft, 6.125" rods, 4.155" bore piston.

 

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.

 

Good info. I'll contact you in Feb/March.

the optional 1/2 inch studs for 550 does that include the studs? what kind of compression normally with that cc piston and a tfs 235 head? any covers front or rear included? sorry for too many questions i"ll give you call with any other questions

 

questions are no prob

$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.
