It's ran 11.5 flat. 410 with iron heads - yes 410 gears weight before 8 point Roll bar, frame connectors, and switching from spooled 489 case 8 3/4 to dana - 2780 without me (220). that was in my street rims and tires also so about 20 pounds less on each front tire probably 10 inch rear tire. Now how much I'm not sure. If I had to guess I'd say about 3,000 Race weight
What rpm are you shifting? How is the 60' after the ss springs compared to before? Did you loosen the front end up? Have you tried different fuels? My 434 made 30 more HP and 25 ftlbs of torque on the dyno with pump 93 over Renegade Crate 98 race gas. No jet changes, no timing changes, nothing except the gas. Plus the timing and jets were tuned for the 98.
IMO unless your iron heads are very good anything past 55-5800 rpms is just wearing out your engine. It would be interesting to see what it would do with a Victor and a 950HP.
My old 340 ran 7.24/11.60 at 3240 pounds on pump 93 and a hydraulic cam, but it had ported Edelbrocks. I think there was more in it with a better fuel system as it was laying down on the big end.
Yes, I think there is more in your car, it's just going to take a bunch of testing to find it. I don't know if there is .3 or not but with some chassis and engine tuning, experimenting with shift rpm .15 shouldn't be real hard.
I understand working with what you have and making do with what's on hand, it's what hot rodding is all about. I'm stubborn and my own worst enemy a lot of times but I learned it's easier if I listen to guys who have been down the road before. My stuff has ran pretty hard for what it is most of the time, not because of what I know. It has ran hard because I found guys who are a lot smarter than me (not hard to do) and asked lots of questions. Don't be stuck on your own ideas and too stubborn to try what someone suggests, you may be surprised what you find. The old saying, "the devil is in the details", it's true
