Im debating with myself if I should get a stock LS engine (lm7 or LQ4) or keep my old sbc when I turbo it. Will be 99%street driven and target 650rwhp, will prob keep rpm below 6500. Turbo is a VS racing 7875 gen 2 and a a2w IC.
Specification of the sbc: stock L98 block, bored 0,02, afr 210 eliminators, SRP pistons (9,0 CR), 3 middle caps billet and splayed 4 bolt, eagle 5,7” forged h profile rods, scat 3,75 forged crank, all bolts ARP.
Gearbox: ZF8hp90 (auto)
Im looking for reliability and Im concerned with the sbc block strength. Any opinions about what way to go?
TIA

that may only require 8/10 lbs of boost.
I'd keep your stock block.
