    I am a road racer but drag racers were running engines like that to 9000 plus, even 350s to 8500. Stock cranks and rods with good bolts. Ported fuellies and tunnel rams. Nothing under 6000 but went fairly hard, as hard as anyone. Just a bit short of durability.
    Though F5000s were running 8500 and doing that for hour long races. Usually had better rods but not always. And even the best 292s on a later 70s 5000 engine flow less than a out the box Dart2.

    Well if that is the same motor in the video of him running it, I played that video and he definitely was well over 7000 rpm sounded to me like he was shifting over 8.Especially on the 1 2 shift almost sounded close to 9. So therefore the stock valve train if that is what he was running would still make that rpm. I have run my share of stock small block 283 and 327 engines and they freaking scream. Just need to adjust the valves with 1/4 turn on hydraulic.

    For our junior year class project we built a 10.90 bracket car out of a 66 Chevy II with a overbored 283, punched out to 292 cubes. It ran a 1050 dominator which required the used of a roller cam, and a tall single plain manifold along with 2.02's and 1.6's for valves. We used the 6" pink rods available at the time, shot preened and polished to make them live longer along with a high volume oil pump and deep sumo Moroso pan with windage screen. The motor retained its 2.0" rods and two bolt mains as the rotating mass wasn't too heavy, but top quality fasteners were used thought the longblock. It was a damn consistent car that took us to second place where we broke out by .01 seconds in the final round. Themotor spun upwards of 9.000 rpm through its journey, so this 301 should be capable of the same rpm if built right!

      The factory parts are indeed a little dicey to take to higher RPM, but bear in mind that modern Pro Stocks were spinning nearly 12,000RPM with 2.5" main journals and 1.888" rod journals. It's not the journal size that would kill it. The balance style/quality and weight of the pistons and rods would factor heavily.
      Yeah, they spun them even higher then, but we don't want to blow up rare old stuff. No need to.

      @port nut Look dummy, a vacuum secondary carb only runs in the primary side untill needed, so a 3310 is at 375cfm on the primary side, and carb CFM ratings are theoretical anyway, just because a carbs rated at 750cfm don't mean it flows 750cfm everytime the engine is running. I have over 100+ carbs in my shop, done many experiments trying different carbs at the track. I've seen the differences myself. My daily driver SBC makes alittle more than 450hp, I've tried a 1850 600 vac, 600DP, 650DP, 700DP, 750DP and a 750 vacuum secondary, it runs the best with the modified 3310 750. Gets the best mpg and has the best throttle response, but if I listened to all the internet experts, I'd have a 600 edelbrock on it. I've been doing this for 35+yrs.
