Ran my car

I finally got to run my car at the track. My edelbrock 600 carb really needs to go, i have put too much time and money into tuning it. I really think all i do is move the flat spot around in the rpm range. Anyways, the track conditions were ok, but there was a 15mph headwind which wasnt helpful.

Best ET of the day:
60ft: 2.058
1/8: 8.894@80.17

1/4: 13.772@100.93

Best MPH: 102.52

I plan on going to a 650 speed demon and hopefully that will cure some of the problems i am having.

Thanks I need to be in the 13's consistantly. My edelbrock carb is getting goofy on me, I will be going to a 650 speed demon and we will see what happens.

They have a friday night thing here where you can bracket race all the local imports and stuff, so i think i might look into that. As for the time, thanks. I think my car will be a whole new beast when i get the speed demon on there. That 13.7 was with some edelbog off the line. I took my air cleaner off after my first pass to see if i could run any faster and i lost 10 mph. Anyone have any idea why that would be? I was thinking maybe its already lean and then i leaned it out even more???

I think you are at the limit for a 600 carb.I know the demons are great carbs but is a 650 going to get it done?Maybe a 750 might be in order.

my advice would be get a standard 4150 750cfm vac sec holley, there's no since in under carbing that thing now, and modding it later and having to change it again. With that carb you'll be adequately fed from mid 14's to mid 11's.

Nice times the first night out with it man, Even thought he carb's beating ya up a bit. that's not bad at all.. traction, and tuning, and you'll creep that down to 13.3's or so. just keep after it, and change things a lil bit at a time.

I actually have the demon now and i can see a huge difference all around. The reason I went with the demon is because my friend was selling his for $300 with fuel bar, and to order it from summit would have been $500 with a fuel bar, so I couldnt pass up the deal. I will run my car this friday and post new times now that I have my Holley Strip mechanical fuel pump and the demon 650 mech. secondaries carb.

As for the other post, the 350HO makes 330 horsepower and 380 ft lbs of torque. I like the motor a lot honestly.
