ok i have a guy that can get ls1 blocks, truck iron blocks with or without aluminum heads ect any options i want basically and he gets them as good motors that the dealers throw out when some1 warranties it(piston slap w/e it might be, or from junkyards ect, anways im looking for what do the lsx guys want?

i see alot of lq4 for sale, but hear the lq9 are stronger rods and pistons and higher compression...
so if i can get lq4 shortblocks what would they sell for?
what about do lq4 come with aluminum heads? what would that sell for?
what about lq9 shortblock? do they come with aluminum heads? and longblock?
is there any other blocks i should look for?

whats any of this worth? i can normally get a shortblock for 150 and longblocks for 250
lmk what i need to buy a few of to make some side money
thanks
