Man it’s easy to twist some math around to make stuff sound good based on some rubbish! Truer words have never been spoken!!! I’d start out with a 5500rpm shift point, and after you have some decent consistency...... try upping it a couple hundred and see what happens. I’d be pretty surprised if your combo responded favorably to 6000rpm shifts....... but that’s why you test. What’s the basic engine combo again? Header size, carb, etc as well. 400/512 10.25 CR .507”/.510 240°/246° hft 110cl in at 105° Unported stealth heads Rpm intake Sniper efi & timing Tiny 1 5.8” shorty headers, 3” collectors, 3.5” dual mufflers (swap meet bargains) 727 tf2 kit B&M 2400 stall 3.21 gear 9.25” sure grip 27.25”ish tire Street build with some compromises for packaging for sure. I figure the headers should be the choke point but the axle ratio and small advanced cam plus standard port heads on a stroker all point to a street build. Trying to be a sensible adult but big headers, trick flow or bigger heads, and roller cams are soo tempting.

That combo will never need to see 6000.
Should live a long happy life.

I can't tell you how may racers I know that had fuel delivery issues, not pressure issues , but once they fix it they went a lot faster It takes fuel and air to make HP Correct,
