i have went from low 13s to 12.05 never faster than 109.something. it's a 416 E heads out of the box , 509/510 comp cam , 4.11 gear , 3k stall 904,MT drag radials, 950 hp carb. weeland stealh dual plane. 1.63 best 60' through mufflers. think it's the dual plane?

What is your trap rpm?

it's always in the 109. something range. i think my best was 109.8

I think the Intake leaves something to be desired yes. Go for something with a bigger plenum like the single plane M1 or Victor if you have bigger bolder plans down the road.

It's just flat making no power.

what do you guys think i should be running with this combo???

I agree your down on power. The 12.05 is a good et for 109 mph but you should be pulling at least 115 mph or better. How does the eng run ?? Does it sound good ? Does it feel like it misses ? I have to agree that your combo should be deep in the 11's. Ron

it being a 9.9 c/r pump gas motor would you still expect low 11s. it has been going faster every time i go to the track. i keep changing things.

Yes, I would.

Keep chipping away at it.

i see what u mean. What can a 416 do? A lot more. i should re ask my question what would help my combo the most. it runs good and feels strong to me. thats all relitive to what you are use to of course. its a cruze in car. i didn't think i was going to be racing it when i built it. But the bug has bitten me. now i am takeing it to the track.

Thanks Brian i see what u mean. guess i wil have to decide if it's going to be a street car or not.I think i will just try to get my best out of this combo then build one of my Darts for the strip.

I think the carb is the "biggest" problem. Try a 750 carb and start tuning on it. (I had jets 3 #'s leaner on the upper level side of the Weiand with a 1" 4-hole tapered spacer.)

I ran a Holley Strip Dominator and a Weiand Stealth, tuning the the 750 Holley DP for each, but not on exactly the same engine. Then I swapped intakes at a weekend event and went faster with the Strip Dominator.....but by less than a tenth. You have more head flow, but I have a lot more duration, gear, converter, etc. I don't think a higher rpm, single plane will help you.

I also have a full exhaust - TTI headers, 3" x-pipe and ending with 3" Dynomax Ultraflos at the rear axle.

What I'm used to?

I'm currently building the biggest engine I've ever ran.......346"

What does your car weigh?
How tall are the drag radials?
How big are your headers and exhaust system?

You must have an XE284H cam?

Not trying to bragg ,just thought it may help.We both have A body's and stroker smallblocks .Mine is in a 64 Dart and its a 408 .It has (unported )Econo W2 heads,a wimp Edelbrock rpm cam ,750 Demon ,victor intake ,an adapted glide trans with 3,000 stall ,and 4.10 gears ,with 8.5 slicks .I have no traction devices on it and i leave at about 2600 on the foot brake.When i got the car it had a best in hot weather of 11.93 at 113.I have gutted 150 lbs off ,made a sealed scoop ,made and welded in sub connectors ,and done sum minor tuning.It has a best now of 11.71 ,but the same mph of 113.My problem is the cam is too small for the gear and im leveling out 100 ft from the end of the 1/4.It has went from a 7.58 best in the 1/8 to a 7.39 in the 1/8 ,with my mods to it.I have gained ET in the first half of the 1/4 ,but gained nothing on the big end.I think its your cam ,and gears that are not letting your motor go where it wants.I plan to tear mine down this winter and upgrade to a bigger solid cam.BTW ,my best 60' is identical to yours ,1.63 ...

any difference without the mufflers?

I think you are close to max on your combo . 60' is decent . OTB Edelbrocks flow can vary a lot sometimes as low as the 230 range. Biggest change would be pull the heads and have them cnc ported , single plane intake , 1.6 rockers or a bigger cam and maybe 1-3/4" headers if you are running 1-5/8 now. Not many cars out there with a similar combo are running much quicker than you.
