Upon further inspection: if this thing uses a sbc, crank there is no need for ls specific pistons and rods.
the conventional sbc with ALL LEFT HAND SBC pistons will work.
the deck height is 9.24
example for a theoretical build:
crank: 4340 400sbc forged steel 2pc. seal 4.00 stroke 500$
pistons:probe brand 12339 400 sbc 6.00 rod 446$
4.165 bore (.040 over) (order all LEFT HANDS)
1.125 compression height 0 relieves
1/16 1/16 1/8 rings
say another 150$ for hellfire rings
connecting rods:
ultra lite I beam aircraft quality 4340 steel billets 335$
6.125length
= 436ci 9.25 deck (.010 out of the hole)
so u can see that these are conventional SBC parts readily available.
and priced way lower than standard LSx parts.
these are not made up parts by me, i went to site that deals heavily with SBC parts and these parts are found in there everyday catalog. i did not provide part numbers or site since they are not a sponsor.
im now starting to really think hard about this motor. i will have to say that at first i thought it wasnt all that great, but im starting to think about it.
it supposed to use a lsx cam core, but what will drive the distributor? and oil pump? mech. fuel pump?

im going to have to a book store tomm. and get it.
i need some more info. now, if my calculations are correct
a hi compression, 430+ci bottom end with forged internals could be built for
4000-4600$ range including block using premium parts, even lower if the regular parts are used.
and it has the superior sbc oiling
steel sbc pans are cheep, dist. and mach. fuel pumps also
its real great value for swap projects or race type builds
not bad attall

Just one extra item everyone seems to be overlooking is the ability to use all the kick out oilpan technology that is available for the early block that is worth as much as 30 HP. The Y block design of the LS severley restricts this technology. This block is not for everyone. Thats why World Products continues to make so many different blocks to try and cover everones needs. This is simply a less expensive way to build LS plus power using alot of conventional parts such as std ignition, fuel pumps etc. One last item to consider is the cast iron LSX block availability has not been so great as of late.

what lifters, what about cam? is it a lsx core, will be ther one available to drive the dist. and fuel pump? seems like not much info is given for cam.
more info please

Valve Train. Std LS lifters, rockers etc. Longer pusrods because of 9.240 deck height with std SB cam height. SB2 cam core works fine as it is std SB diameter and has lobe positions for semetrical head and has distributor gear and fuel pump lobe.
Standard SB waterpump bolts on and feeds water into block. Water can exit heads front or rear (what ever fits your car better) using either World Products end plates or some people may choose to tap end of head for AN fitting.
Can cores are a little pricey and you need the valley cover to go under std LS manifold and LS heads in general are more money then std SB as they are a more complex casting making this whole deal cost 1500 to 2000 more to build then a std SB Chevy, however the block being cast iron as oposed to aluminum and no need for expensive ignition makes it about 4000 less to build then an LS with the potential of having more HP than either and with both motor mount locations on the block it will fit in just about any application. I guess thats why they call this Hot Rodding.
