302 HO

[BlackHawkA4]

Alright, I just bought an 86 302 HO for 380 bux. 86,000 miles on it.

I have 373s w/ trac lock, cold air intake, stock headers, off road h pipe, and turbo mufflers. What am I looking at in the 1/4 with the new motor? 86 has 200hp. What am I pushign right now?

150 stock. 86 HO motor is no big deal. Same thing you have now with a different cam. It doesn't have the relieved pistons, doesn't have the good heads which amounts to an engine with no low end torque and no high RPM power. Bit pricey for an 86 motor if you ask me.

Should be easy 15's with that motor. If that motor has healthy bearings, you got it at a decent price but Explorer motors can often be found for $100 more.
Find yourself an Explorer intake, throttle body and injectors. Even though the Mustang pistons are lacking reliefs, they are still forged unlike the CV/GM pistons. You can bolt E7 or even GT-40P heads any may not have to cut any eyebrows because of the GT-40P heads having standard 302 sized exhaust valves. With the stock HO cam, the intake valve probably has plenty of room. It is an easy check for clearance. Think of the lack of reliefs being a boost in compression instead of a negative.

You should have gotten an 87 up HO.

The '86 GT ran 15.05 stock back in the day. Your looking at 15.5's ideally with good driving for the heavier CV. Should be easy with your gears and TL.

Figures for the '86 200 hp @ 4000 rpm, 285 ft-lbs @ 3000 rpm.
Figures for the '87 225 hp @ 4000 rpm, 300 ft-lbs @ 3200 rpm.

About the only difference was the heads/pistons.

I think you did pretty well, $380 for a 100% complete HO w/86K sounds good to me. You can sell the extra parts (like the headers to me) and buy some better heads.

I have headers on my old motor you can have when I pull it. I was thinking maybe get a set of e7 heads for it with all that was said. How much power and torque would that get me. What would that get me in the 1/4's. Just curious.

I will deff sell you the headers when I get them off. Anyoen want a set of turbines? LOL

with 3.73's and traction i think u might be lookin at low 15 maybe like a 15.3

I highly doubt that...I'd say high 15's or low 16's

[BlackHawkA4]

Now wait if I swap the heads... wouldn't that fuck up how the car runs...

I have to agree here, though I am leaning more towards the low 16s. But he is going from an EFI engine already, so in comparison to all the guys that had an EFI and went to a 87+ HO, he is only going half way in terms of HP gains.

[mrltd]

Only if you fuck up the install

You will need an HO computer regardless of the heads you run. The E7's with a stock cam will run fine.

[BlackHawkA4]

Yea the guy is looking for his old comp.

[Grand Marquis GT]

I do agree the car will run better...

A few yrs ago, I bought an 86HO motor for $200, unknown miles, junk lo-po CV heads. Added my 83/84/85 Stang intake and carb, basically making it an 85 engine, shorties, AOD, 373s and eventually went 15.66 at 88mph in my 4200# wagon.

That engine now has fresh E7s milled .025 , has no clearance issues, and is ready to drop into my daily driver.

If you are using EFI, with a good flowing intake and a fuel pump that can keep up, you should see mid 15s.
Stock CV intake, lo 16s.
