Later this week I'm going back and will have all 4 bbl operating. The engine is a 451 10:1 CR, CNC ported Ebock headsJeff @ Modern, mild like 245 @.050 cam Scott Brown, carb is a Demon 850 Vac sec. 3.23 sure grip rear. Auto tranny. TTI headers and 2.5 x pipe exhaust all the way out the back. The car is all stock except for the engine, exhaust , wheels and tires. I didn't weight it last week but will this next. What do you guess it'll run on all 4 bbls? Last edited by HemiRick; 08/30/11 12:33 AM. Take care, Rick 68 Coronet R/T 440 & 68 Charger 528 Hemi,and 5 Challengers! 6 cyl, 318, 360, 383, 451

My SB duster went 11.50's@115mph on 2barrels and leaving in second gear.Hooking up the secondaries and leaving in 1st went 11.20 @120mph with lot's of traction issues and no tuning.

My assumption is that the engine was running out of RPMs sooner on just the primaries, and the optimal shift point is likely different between the two experiments. Did you experiment with shift points? What were the incrementals on the 14.09 run? I wonder if the times show the car falling off on the top end. Did you have anyway to confirm the AFR was reasonable on just the primaries? Look forward to seeing your results.

Besides if it goes much faster at the track, will have add a bunch of safety equip. the rest of time slip is this 60 ft. 2.144 330 ft 5.09 1/8 9.03 @ 78.2 MPH 1000 ft 11.77 No LM1 or way to confirm AFR. I just made 1 pass and let it shift itself. Didn't even load the converter. I'm sure it has a lot more in it, just with improved driving technique. The Charger will be the race car eventually.

I'd think a driveshaft loop and helmet would be ok to 11.50's. They get mad at me(Gainesville raceway) I make a few adjustments and run 11.50's. Last edited by goldmember; 08/29/11 11:38 PM.

I was mad as hell at first, but then decided to walk back out to the car during dinner and check the carb. Sure enough, secondaries weren't opening (cable maladjusted). Fixed that and the next time out, 11.40-11.44.

It will still be a stout street car , but a gear will be the cheapest and quickest way to get that car down track. Some suspension tricks will give you some gain , but if you don't see a 1.7 60 ft. or so , you will never see the kind of time slip that car is capable of.

Then 14.0s, how much faster are you talkin when you say "if it goes much faster", If say it runs 13.0s your still good, just need a helmet, maybe a DS loop, but thats good insurance anyways, you don't need a bar or special belts/harness. I ran 12.5s with nothin but a helmet & DS loop. 75 Duster, 451 10.87 @ 123.58 NA 97 Z28 6sp., 12.01 @ 115 on a 100 shot 71 Swinger. 360 magnum. 12.58 @ 105 78 cutlass, 469 BBC. 12.70 @ 108 on street tires. http://www.youtube.com/watch?v=Z2kqNmMfheU

With the trans in drive, it likely short shifted, but given you were only on the primaries that may have been what the motor wanted anyway.

The tech guys said I needed a driveshaft loop with those so when I go back will running a set of MT I blocks, and they should hook fine too. I hope Jegs gets me the lug nuts I need by tomm.

I have run several cars with the secondaries disconnected, went from 4 barrel to a two barrel etc., and on average it's about a half a second.

Being that it had only been street driven and was plenty fast, I hadn't bothered to mess with this issue. It's fixed now. I'll be going back to next Tues TNT.
