Raise your shift point. That cam and 3.55 years should like around 5500rpms. Also try riding the clutch out of the hole a little bit. Don't use the water box in the burnout area. Just give a quick little spin of the tires to clean them. Then stage. If you're just worried about a time don't worry about cutting a light. The timer doesn't start until break the beam. Just concentrate on staying in the tire groove going down the track(you should be able to see it) it will be the stickiest area for you to gain some traction. Make clean shifts and write down everything you can i.e. Air temps,tire pressure,shift points etc etc.

Also make sure you're running good fuel and as much timing as you can(should be around 14* adv). Most importantly have fun
Thanks a lot man, I appreciate the tips !

I will report back...running about 96 octane fuel but I can't adjust my timing....driving my car to the track so I can't really drop the air pressure lower than 30 but I hope it makes a difference.

Just a FYI
If you have the suspension sorted and a good bias ply type of track tire(slicks are obviously best) you have a 12 sec etc in that car.

Skip the nittos and go for a Mickey Thompson ET street (either radial or bias, bias are better for a stick but radials can work), even if it's on some spare/cheap rims. You'll be way happier, been there done that. Should be in the mid 12's or faster as @A5literMan said with that mph.

As of right now I can get a set of Nitto N555r's for roughly $200 cheaper than the Mickeys...but I'd be going to a 245/50/16 compared to the 255/50/16 on the Mickey's.

Think the Nitto's would hold up? It's just a substantial price difference on the Mickeys.

lets just say i went from a 275/40/17 555r to a 245/45/17 bfg g-force sport (not the drag radial, just a summer tire) and didnt go slower, and actually a touch faster. the nittos arent much more than just a regular summer tire with a bit less tread.

Ended up grabbing a used set of Nitto Nt555r 245-50-16 drag radials....they are about 75% tread. I wanted Mickey's but ended up grabbing this set incredibly cheap.

Planning on hitting the track one last time next friday...hoping to hit mid 13's with these tires.

288/303. 306, TFS 170s, TFS stage 1, Holley Systemax, power pipe, 80 MM Maf, 75 MM tb, BBK shorties and h pipe. Maybe there’s more in it with some long tubes?
I assume a9l?
The stock ECU is a bit weak on its timing curve, how much timing and at what afr?

Stock computer and an ancient Superchips. It was in there when I bought the car. I know you and others will cringe, but I have absolutely no idea how much timing or what afr it’s running at. I leave that to the professionals.

lol. its good information to know and for future reference you should always ask for them to be printed on the dyno sheet. :)

Recently purchased an 85 GT and it came with a time slip. :)

Mods are:

351W (F4TE block)

Ford "F" cam
AFR 185 heads (#1422, 58 cc)
Edelbrock RPM Air-Gap intake

Holley 4150 (4777-7, 650 DP)
3.73 Rear end gears
Tremec 3550
Mickey Thompson ET Streets
Southside Machine Lowers.
Stock springs.

Any guesses on HP/TQ? Also, any suggestions to get more power out of this combo? Thanks!
