Heads ain't holding him back with what's goin on now. He may be in the right track with his converter tho.

We'll see once them heads are swapped, but yes if OP believes theres some converter slip,id bet its certainly affecting the results.

Would converter slip also cause the terribly low tq on the dyno?
Certainly could be the culprit for the sub par e.t. and mph.

Idk......i hate tq converters

If it's not coupled then i could reduce power i suppose. Just turns it to heat. But it would be drastic in his case.

Before the PI Vigilante 4000 10.5" Multi Disc and 3.73s the Car Ran a Best of 12.73 @ 111 with a 1.98 60ft with the Stock Converter and 3.23s. After the PI Vigilante 4000 10.5" Multi Disc and 3.73s the Car Ran a Best of 12.23 @ 110 with a 1.68 60ft. IMO It's 1 of 2 Things Short Shifting or Converter Slip, When the Car Trapped 111 Shift Points were Set at 6500, When the Car Trapped 110 Shift Points were Set at 6400, The Car Made Peak Power at 6290 and Starts to Fall Off Drastically After. Should I Raise the Shift Points with Power Falling Off? Should I Command the Converter to Lock Up at WOT?

Something is off...should be well into the 11's with a cam and converter. I know two cars that have less cam and less converter that run 11.70's. First thing I would look at is the tune then the transmission.

I had the exact opposite when I removed the FIPK.

5LTR, are you data logging your runs?..

The thing is you should be nearly where your at with no cam and no converter.

My old SS was the same way.. heads and cam trapping at 113 scraping 11.99 barely with 1.6 60 ft.. car would feel awesome out of the hole but wouldn't pull hard the rest of the way... never figured mine out but I suspected a bad tune, poor compression in a cylinder, or maybe an intake leak or something.. a few weeks after the track I blew a hole in my piston.. no nitrous or anything.. yours may be different but I suspect something is off or the tracks timers are off lol

Just to add, my car did decent on the dyno also and the reputable tuner said my injectors were not maxed.. who knows... I just know it wasn't right somewhere.

Here's an Update Guys, The Stock 853s are Off. The Lingenfelter CNCd 799s are On, Along with GM LS7 Lifters, GM LS2 Lifter Trays, GM MLS Head Gaskets, GM Head Bolts, BTR Titanium 660s & CC 7.375" Pushrods Due to the Heads Being Milled to 62cc. Guesses On Compression, Power, ET & MPH Gains?

It was Street Tuned, It Goes On the Dyno May 18th.

Better but it should be running faster than that. Could be the converter, maybe the cam...it shouldn't be dropping off that fast after peak HP.

Maybe the Dorman LS6 you have is poorly built and extra restrictive?

I would do a leak down test.

Also, another member had a wonky MAF and after replacing it, he picked up a bunch. Maybe try someone else's MAF to test it out.

Good luck!

Two things to think about.#1 Condition of your trans. #2 I got that dorman intake and the one I got was junk would never run it on a h/c car now I have a fast 92.

Bet she traps 117+ with a fast 92/92
