What the hell are you talking about? Head swap, 91 not a good year.... 85 through 93 were fantastic years for the 5.0, some could argue 86 wasn't for obvious reasons the biggest of which was swirl port heads.
Some simple work on any 87 to 93 fuel injected 5.0 with stock heads, stock computer can get you into the very low 13's to high 12's, on the cheap to say someone needs a head swap and that 91 isn't a good year speaks to how little you understand the 5.0. Not to be a dick but giving out crap advice like you did doesn't help, it hurts.

 

Acutally, the '86 put out 200hp, I give up on correcting anything else...

 

Does the short shifter have stop bolts on it? What rear gears are you running, the stock 3.08's or 2.73's? I believe you said you have a convertable, this gets you a little bit heavier. Explain the ram air, is it a CAI or one that runs into the fender? Has the timing been changed or are you running stock timing? It's soooooo easy to get that car to move faster give me the details I've asked for and I can help.

Oh yeah, have you bypassed the intake water lines? Install a 160 thermostat, bypass the coolant line running into the intake, bump up the timing, use better gas after doing so and if you do race him make sure you have that engine as cold as possible, it will make a difference.

Some easy things to do to get some kick out of that 5.0 also are to have the heads worked on, a simple clean up and port job will make a big difference.
My buddy went 11.01@125 with an '86 LX Hatch, a Paxton supercharger, '87 heads we opened up and cleaned up ourselves, bypassed power stearing, full headers, custom blower cam and a completely stock '86 shortblock and a stock computer, oh yeah, bleeders because the SOB was speed density, a switch to MAS Air was done a year later.

Don't think that because you're running a Fox and a 5.0 that you can't make some serious power, you can, and it won't cost much.

 

i think you should race him and find out!

 

Oooook, where is he?

 

If it is an 04 than I think he will win.

Ive seen stock 04 SRT's run high 13's all night long. Not unless you know how to launch and powershift hard.

The only thing you have over him is torque so you going to get him out of the hole. But he is lighter and has more hp so he might beat you on top end.

Get some 3.73 - 4.10 gears and some good tires and leave him at the line. That way you'll have a beater chance of outrunning him before he can catch up.

GOOD LUCK

Tell us how the race went!

 

i asked this question, just was wondering.

 

I have the 3.08's, my ram air comes up along the fender, not CAI, and stock timing. No the water lines have not been bybassed. I would appreciate your help. I am only a senior in highschool so anything that will improve my stang's performance cheap will help.

 

The only things for free that i can think of is:

Advance the timing from base 10* to about 14-15* (this can be worth up to 3 tenths in the quarter mile.)

Powershifting

Gut your whole interior

Bypass the a/c, p/s, s/p with a shortbelt (about $10.00)

Heat the sh** out of your tires

Pray for a good launch!
