chryco OP super stock Joined: Jan 2005 Posts: 866 Winnipeg ,Mb. CA.	I had the car out last weekend testing a new converter and really think my et and mph should have been better. My 2800# Dart with a 557" aluminum hemi .750" lift cam , 12:1 comp, tweeked heads , Barton intake w/1150 , Dyno`d @ 875hp @7000 / 750ft.lbs @ 5200 ran 9.71 @ 139.4 . The car felt like it was running strong and seemed to launch OK with the new converter ( Neal Chance custom 9" 5400 stall )and trans brake 1.39 60' . I think there`s more , but where ??? Ideas thought? Chryco Last edited by chryco; 09/29/12 10:10 AM. Gas is fer washin' parts ....Alky`s fer drinkin' ...Nitro`s fer Racin'!

BTW nice car

Based on 875 hp and 2800#, you should be running high 8,50's at nearly 160 mph.

The old converter was in my opinion a screw up on the part of the manufacturer even though I gave them the complete list of specs , they sent me a 4600 stall 9" . My 60' went from 1.45 to 1.39 NOT what I`d expected BUT an improvement just the same.Last time out there was a lateral cross wind 35 - 40 mph and I ran the 9.71 The previous time out VERY humid and hot with the old converter I went 9.74 both at the same MPH 139. Which is why I thought I`d have had bigger gains with the new converter. Thx chryco Last edited by chryco; 09/29/12 08:14 AM.

I haven`t altered anything since it came off of Barton`s dyno as far a timing or jetting . I`m at 750' elevation and am pretty sure it`s not that far off where RBRE is located. New plugs and oil oil pressure`s fine . I`m going to pull the valve covers and hope for the best Sunday , I`ll bet my valve lash is OK though. I`ll also leak it down too .

Again , there`s no miss or hint of actual power loss other than what the dyno results would suggest. Chryco Gas is fer washin' parts ....Alky`s fer drinkin' ...Nitro`s fer Racin'!

Running 9.70s, everyone says it should be a sec faster, that thing , if it is not laying down, misfiring, boogging ,blowing the tires off , and tuned way out , those dyno # are wrong, Something amiss in the build of the motor!! Get a leak down on the motor after it is hot!! see what the # tell you then J M O

Also where is your timing, rear gear, jetting and carb size? what RPM are you going through the traps? Head flow numbers would help. There's more there for sure but the combo needs to be right. I'll go back over your post to see if I missed anything, but it takes around 950HP to run 8's at sea level
