Peak HP from LA block w/ no problems

I have no "set" goal of HP. Like I said, I rather have a motor with more torque vs. a 500 hp screamer. Cant emphasise enough, Im not into putting a high RPM drag motor into a street musclecar. Its never been an option, and the thought has never crossed my mind. Not into needing to change plugs because i stopped for a traffic light. Been there, done that.
--My initial concern was just to be sure the HP figure quoted as a "safe zone" was conservative. {It must be, because if you take a stock spec '70 340, put good headers& exhaust, intake & carb, and a well matched camshaft you just added 80-95 HP over a"healthy" stock 275 hp motor. Hughes stage II heads with an airgap intake will add 50 or more HP. Your right at 425-435 already.}
--So just based on those facts, by doing a 4.00" stroker crankshaft the engine output wont diminish.. So knowing that it WILL be making MORE than 430 HP, brings me right back 3 paragraphs. "My initial concern"......I just dont wanna build something Im a gonna break :) .
--from the various parts list and specs ya'll provided for me (thanks!) looks like I'll be just fine. I have to say compared to some of the dyno graphs posted, Im looking to be a bit more streetable. I'll be letting the fine folks at Hughes Engines match me a good cam . The wildcard is IF we decide to stroke..will dictate what cam is best.
