If you are running the stock rims that has to be a lot of weight right there .

And if you have a maurader that is close to 11's in the 1/4 you have at least 450hp . I would think at 5,000rpm your engine would still be pulling like a freight train . I bet the 4.10 would help you . BUt you want a 1/2 second knocked your off e.t. so you're going to have to look elsewhere too , like better tire and weight reduction . Or trans and converter work if you haven't done that already for a good launch .

Who locally can redo the tune? I get the slicks part. MTs perhaps. Last year in cold air the car did run 12.19 at 116 mph. Tune may be timely because I need to pass the non-attainment area smog inspection which involves putting the stock tune back in and then getting enough drive cycles to reset the emissions tests. I need to pass 5 of 6 in MO but I automatically fail one of the 6 for missing 2ndary oxygen sensors.

Last dyno was 487 rwhp & 494 torque. TC is new OEM. Trans has been beefed. I race with the spare tire & tools removed. My best 60 foot time is a miserable 1.89 sec.

Dr's on 15" rims, an aftermarket TC with the appropriate stall and 4:10's. I dropped more than a tenth in my 60' times going from 28" tall MH-DR's on 17" rims to 30" tall (stock tire size) MT-DR's on 15" rims. A stalled TC should drop it anothe couple tenths on the short end and the the 4:10's may keep you more in the powerband through the traps.

However I do not know the 4.6 DOHC drivetrains so I may be wrong... as I aften am.

I would bet my paycheck you got a great number on the dyno then it was backed off when you rolled out of the shop. It HAPPENS.

The easiest way to go 11's in a Marauder is to put race gas in and add 5* of timing. You will go .5 seconds faster MINIMUM.

I went 11.99 years ago with my Eaton swap. I did the race gas and timing to achieve it.

11's on 93 octane in a 4500lb car is difficult.

My spark table on 93 octane was 13 at 6500. So I had 18 degrees at 6500 with the added timing.

Anything over 13 degrees and I could hear the faintest of detonation now and again.

21 on race gas is a lot for 100 octane. You may be able to stuff a few more degrees in with the 109, but I strongly suggest listening for detonation on the street, without the helmet on.
