Whos running 11s with an NA 5.7 and whats your weight and combination?

I ran my 73 Challenger a couple of times NA and ran 11.86 at 111.30 mph. The torque converter was loose and very inefficient. ET and MPH would have picked up with a converter adjustment.

2018 5.7 Hemi
Prefix Cascar Intake
Holley 1000CFM Throttle Body with Holley HP Engine Management
TSP Cam 226/235 .582" .582"
727 Trans 4600 stall 9 1/2" converter
4.10 gear
29.5" x 10.5" tire
3650 lbs

I have since added a Torq Storm supercharger and went 10.49 at 130 mph.

Not an 11 second pass but very close.
1st time out in 100 F temps
12.01 @ 111
3525lbs race weight
5.7 eagle, SRT car headers, 209/216 @.050 crower cam and 6.4 intake manifold.
727 5k stall
4.88 gears and 28" tire.
Still a fair bit left in the tune

Are you still running the dual runners on that intake with all that stall and gear?

I played with it using both lengths and just the short. It was much better with the long runner as well. Made it flash on the converter and hit the tire harder.
For 345 cubes it had the bottom end torque of a LA 408 stroker

My 2014 Ram RCSB 4x2 ran a best of 11.19 @118 , weighed in at 3800 race weight with the 518 trans ...truck was a rolling tin can at that point.

Made 3 passes last summer at Island over in NJ , 1st off the trailer was 11.90 @115 , next was 12.20 at 110, last pass was 11.86 @ 120.8.


Intake valve size is actually 2.165 , not 2.15 listed above.

Man 120 MPH is hauling at that weight, what are you running for tires?

M&H 275/50R17 Drag radials , I was wrong about the Intake valve size, it's a 2.165 X6 MM
