557 Purpleshaft - How fast have you gone? - 09/03/14 05:15 PM
How fast have you guys gone with the .557 purpleshaft? Tell us what the entire setup was.
I'll start. I know a car that went 10.97 at around 3500 lbs with a 4 speed and 5.13s with hogged out 906s and 12:1ish compression. Weiand Team G intake, Hooker Supercomps, and a Holley 850 DP.

Back a while ago I read a post that W2DODGE went 6.6's in the 1/8 with a 360 small block and W2's. He had 1.6 rockers I think and was around 3,000 lbs. That would be mid 10's in 1/4.

These are great ET's for a very mild cam! I went 11.80's at 115 with the 557 in a 3200 pound 340 Scamp, very mild motor.
My current project is a 500" street Duster with the 557 cam, hope to drive to the track and run 10's. I will probably go with 1.6 intake rockers though.

Not the PS .557, but i ran a best of 10.91 @ 120.56 (on a 1.51) with an XE284H cam, completely stock 906s, 9.73 compression, M1 intake, 750dp, fenderwell 1.7/8 headers, 4400 stall, 4.10 gears shifting at 5600, race weight was 3150. 75 duster.
Went to a solid comp 282S cam, ported the heads still keeping the stock valves, Wieand TR with 2 600s, 1st. pass un-tuned, On a bad 1.63 60ft. in the heat it ran 10.87 @ 123.58 shifting at 5800
So high tens are doable at 31-3200 lbs. with the .557

I used the .557 in my old 440 that was in my 63 as it was a mild 10.0 comp 906 headed pump gas street eng. Also have the .557 in my sons 400 Dart and both have run 11.40's at 116 and 117. My 63 is 3700 lbs and my sons Dart 3550.
My brother went 10.0's with a .030 over 400 (406) in his 2600 lb 68 Cuda as that 400 had Eddy RPM heads and a Team-G with a dominator. Ron

I have been as fast as 10.90 @ 123 with my 8.5:1 small block with a .528 purple shaft. 2700 lbs and 2.02 stock "J" heads. I know it is not the .557 in the heading but it is totally attainable with the right combination. 4:10 dana gear shfting @6200 and trap rpm of 6000. Best 1/8th mile was 6.82 @ 98mph.

10.60 around 125-126 in a 1965 Plymouth B-body. Weighed 3460 with me in it. 11.51 440 out of the box eddy 84 cc heads.tunnelram 2 750 edelbrock carbs. Indy 1.6 roller rockers, tti 2 inch header. 727 8 inch turbo action converter. 8-3/4 4.30 gears M/T 29.5X11.5X15 slicks.this was a great combo until I wore out the factory eddy head springs. I went to the Mopar 312/590 solid can when I upgraded the efelbrock valve springs.
