Why in the heck if your engine is designed to make max power at 7,000 would you want to rev it out close to 8,000? That is well above your peak power and will not be doing you any good other than to harm the engine. If who ever built your engine set the valve springs up according to what the cam manufacture recommends you very well could float the valves. Not only that but unless you did splayed 4 bolt main caps and not just the standard factory caps I would be leary of 8,000. Heck for that matter I sure hope you used the best fasteners that ARP makes because thats going to be huge stress on the rod bolts.
I know alllllllll about 383 strokers. Mine is 13.5:1 compression with a .650 lift solid roller cam topped with fully ported brodix track 1 heads, victor jr intake and a 1050 dominator carb.
Depends on the camshaft.
For example, the TFS #1 in my Mustang made peak power at 5,800RPM, but didn't fall-off, the power curve just carried on past that point with VERY little (like 2-5HP) power drop-off.
My custom cam from CI is supposed to (it has yet to be on the rollers, car isn't done) pull to 7K, but peak will be down near 6-ish. Same scenario.
Jay Allen of CI had a rather bizarre GT40 headed 302 setup that was spun to the moon. Engine made peak power in the 6's, but would carry the curve. Car was shifted at upwards of 8K at times to try and optimize ET. Car ultimately went 11.19 @ over 120Mph shifted in (I believe) the mid 7K's, not bad for stock heads in a full-weight car
