With 4.10s he could easily see 120 and VERY quickly at that. He could hit 105 in 4th gear man. Say he drops in a set of 4.10s he'll be crossing the 1/4 line in 4th and in the mid 90's (say round 94mph). If he keeps on going and get's in 5th there's not much problem reaching the 120mph mark but that's probably about all that'll be gotten untill he upgrades to more power. But on stock hp he'll see that quite easily.
As far as shifting with the 4.10s if he uses 1st, which you pretty much won't need to except for racing, then yeah he'll shift alot. Otherwise it'll be like driving a 4 speed around town when starting out in 2nd. 2nd will roughly be around how his first gear operated with the stock 2.73s. 3.73s or 4.10s are very good gears for the 4.6. Like I mentioned in an earlier post the power band of the 4.6 is way up there in the rpms so they need some gearing to get the motor wound up there to get the power. My personal recommendation is 3.73s unless you frequent the strip alot then go with the 4.10s. If you plan on a blower in the future actually the 3.73s would be the better gear to get a bit better top end mph because the blower makes up for the low end torque. When I jumped from my stock 2.73s to my 3.73s my ET dropped .4 from a 15.4 to 15.0 but my mph also dropped, instead of increased, from 94 to 92 mph. It won't make much difference really.

Well...we went to the track and I forgot about this post. The conditions were pretty bad. First day and the track was pretty slick (worse than street)...I ran a 15.02 with 8* timing. With drag radials and slightly better conditions, I don't think a 14.7-8 is unreasonable... 98GT5SP ran a best of 15.6 or 15.7...And despite his earlier quote about guarenteeing not missing a gear...he missed third and stalled once (but the stalling was kind of not his fault...just to be fair).
My info: 15.02 2.3-something 60' Low 93s trap. NOTE: The run was not made with what is in my profile currently . (had 3.55s, 8* timing, catback, MAF, cold air intake). Thanks, DoranW

Why only 8* timing?
These cars run best around 14-16*. You'll pick up noticeable power by bumping your timing.

Absolute minimum timing should be 10*. That's what the stock timing is supposed to be. Like 89 Cobra said bump it up to around 14* and drop in some 91 or so octane (what ever you can run without getting detonation). What's your elevation out there in WA? Both of ya'll will gain some better ET with some driving practice. Now 98's car is bone stock right (gears included)? That stock shifter is a pain to race with. Been there, done that. I'd bet he also had around a 2.4-2.3 60 ft.

I couldn't have imagined that we would have been more than a few hundred feet above sea level. (We were in Kent, WA at Pacific Raceways...formally Seattle Internation Raceways (SIR)). His time was with JUST exhaust and the cold air induction setup. He got gears after that run. You are right about his 60' times...one or two of the runs were actually higher I think. Thanks, DoranW

NW Stangs
Sonics, good to see someone from the NW. Im stationed at Ft. Lewis, though Im at Ft Benning, GA for training. Just bought a '91 LX that is all engine( less that 2000 miles on it). The guy didnt get to the AOD tranny. That is my weak link with that car rite now. It does shift perfectly though. This is my first ford so I know very little about their Auto Trannies. The lentec valve body someone was talking about on another thread sounds interesting though.

Tremec purchased the trannies, or the entire company Borg Warner a few years back.
I don't know anything about the Tremec 3650. The 3550 isn't anything close to a T-5. It has much more in common with the Ford toploader and SROD transmissions. |
