hi, i'm reading a lot about building a stroker from an SBC i picked up an running 350 2 bolt V1101CKR GM 3970010 ( also 010 behind the timing chain and by the oilfilter ) is this an high nickel engine ? the most common is building an 383l but are there other good options ? reading also about 406 or even 427 strokers. my plan is to fully rebuild the engine, convert it to 4 bolt or wich full brace "10 bolt'' aluminum heads and higher compression. but what to do, 355 / 383 or even more.
