Need advice

[Chris1973Rr]

I'm looking to run a .484 lift 284 duration cam 3.55 gears and a 2800 stall can I achieve 12's with this setup

I ran a 13.3 with this setup with an oversized carb and performer intake. I believe with a better intake and 700 carb it would've went quicker 12.9? Maybe

That's exactly what I'm looking to get thanks for the info

 

[SUPERSTOCKRACER]

If you're perfectly tuned, I think you might just get that elusive 12. And the Density Altitude is low. But if you're over 1200 DA chances are slim, I'd think yo might get it in spring and fall air but not in the summer.

Do you remember your MPH on those low 13 sec. runs? Thanks.

Thanks. Don't go out of your way though. I was thinking the MPH will be a good indicator of ET potential for the OP when he starts making passes. He'll probably need 105/106 mph to reach 12.90's? Meaning, new car combos and 60 foot times usually aren't dialed in at first, but the speed can be there.

Think you're pretty close 105-107mph will probaly break into high 12's

Also the carb I would like to run would be a 750 screamin demon carb with vacuum secondaries will this work with that setup

All this talk, and not yet the one most important question to be asked. Is this a 440 or 383 or whatever were talking about???
Makes all the difference in the world as to the answers.

He had it listed in another thread it's a 383. Should have been listed here as well though

Sorry 383

About 3500

Just curious about the 3500 lbs., has the car been lightened? Stock, they're closer to 4000 with driver.

 

[forphorty]

Yep, 73 RRs are heavy . Are you married to the 383? It would be much easier to reach your goal with a 440. A 383 with stock heads, 484 cam, 2800 stall and 3.55s in a 4000 lb car is gonna be tough to get into the 12s.

I hate to break it to you but I don't see that combo doing a 12. If things go right you will probably be a high 13. Even that is not a given. I like to think I am wrong. With a 440 chances are better but only marginally. 3500 lb car will need more gear and converter with good sticky tires to make that goal number. With a 4.30 gear or better With a 3500 converter and slicks you may make a high 12.

I think you're on to something.

My 72 scales 4050 full of fluids and driverless. If the 73 is heavier expect more than that. Do not trust the tag weight, get it scaled. According to tag weight a 72 should weigh 3600.
