No IAT (ACT) sensor location in the lower either which is not a huge deal. You can relocate it if NA to the airbox like newer cars. With an SC'ed car is MUST be after the SC. It will not get heat soaked as bad if located in the air box or intake piping either. Dyno chart of the Explorer/Cobra/GT40

Normally you will pickup anywhere from .3-.5 in the 1/4 with them. I think out of stock gears 3.27 are the best. I could still hit 137-140 in 4th with them, I don't care to lose my license so I never got that fast anymore anyways. I know going from 2.73 to 3.27 was worth .3 in 1/4 in my cousin's...

LMAO Well there really isn't any sense in dumping $300+ in rebuilding some, plus add cost of valve springs ($125 or so). The E-Street Edelbrocks are a decent deal for under $1k new. I think MM&FF picked up another 30rwhp over GT40P with them. I would toss GT40P on in a heart beat if they...

No idea, I did know a guy with a 93 Saleen that had 3.08 gears and it would do 160+ h/c/i/sc'ed but I'll pass on that lol.

Just an FYI but you can buy the SVO foam and seat covers and install them on regular seats as the frame is the same, it just won't have the manual lumbar. The only Recaro seats are early Cobra and Pace Car.

Another one I like that is also T304 is the Steeda system, I know I never read anything bad on SVTP either about them. I would definitely go with a T304 vs. T409 though. Steeda Autosports 040-13868 - Steeda Autosports Stainless Steel Cat-Back Exhaust Systems - Overview - SummitRacing.com

I have seen dynos of different catbacks but don't think there is much of a difference. I do like the look of the stainless systems like Bassani and Borla. I remember reading up on this a few times in the past when a friend got a 03 Cobra new and then another friend got his 04. The T304 systems...

Yea, I wouldn't dump a ton of $$ in some but they work pretty good.

Still have it and it is not ported.

Oh ok. I'd take a look at the heads and see how bad they are myself. That sounds about normal for a rebuild on heads, I'd get them checked 1st you may not need to have a ton of work done on them. Or PM EHA Racing and ask him what that normally costs? The lower intake doesn't have EGR.

For what?? LOL. They are good for high speeds that is about it, and good mileage on the highway. For performance they are horrible.

I have piles of 2.73 and 3.08 around here. LOL

The MDS digital has a timing retard that you activate with a switch, you set it to whatever you want it to be on the box.

I would have grabbed the whole motor lol.

Sounds like you probably should have kept the auto if you hate shifting lol. But 3.08 or 3.27 might be your best bet.

And you went from a 2.40 1st gear AOD to a 3.35 1st gear T-5 too so that's much more gear.

I like 3.55 with a Kenne Bell, I ripped off 1.5x 60fts with one and those gears. 3.27 would be a nice gear as well, that's as tall as I would go personally. Another option would be 3.31 since many of the newer Mustangs and trucks come with those.

The 1st one is the stock 07-09 GT500 gearing and in 2010 they changed it for fuel mileage 10/11 GT500 gear ratios 1st 2.97 2nd 1.78 3rd 1.30 4th 1.00 5th 0.74 6th 0.50 I think you have the right idea as far as the gears being closer together. As far as 5th/6th thats up to you. The .74/.50...

I used to keep secrets kinda but thats when there was local competition going on...those days are over lol.
