Default Need some block info please.

I have hear some casting numbers off the block that i picked up this week in the start of freshening up my 388 inch stroker SBC it is 13to1 on 6inch rods and makes roughly 550 horse at flywheel on motor. Kinda mild by the way heads and camshaft wise. But was wondering if this block is inferior at all to an oldschool 60s and early 70s block like some people will swear are the strongest but the main caps are more rounded and smooth than an older blocks seeming to b a better idea in my oppinion. This work horse is a very low end quick revving engine that turns about 7000 rpm usually and will have somewhere around 150 or 200 shot. Anyone have any usfull information for me based on the info i placed below. THANKYOU


10066036...350...........2 or 4...Target Master/Goodwrench crate motor, 2-piece rear
seal, "Hecho en Mexico"

they make a manual called " ziggy's small blocks " its a manual with every small block casting number coded out, it has alot of info, i think you can order it from jegs or summit. my ziggy's, unfortunately, is buried under piles of rod pieces and spun mains but ill try to dig it out and check for you.
