your telling me a 91-93 5.0 is an HO of the same size and will fit inside an 86 LX?
A 302 is a 302 no matter how you slice it

with only the having to fix the wiring and the springs well if it has more power than the 86 HO I will probably have to take the breaks as well and the 8.8 LOL hmmm now just find a smashed up 91-93 doner car
and just find an SVO spoiler
The 4 bar carb 85 GT had 210 hp, basicaly the same hp as the 85.5-86 SVO. Anyways the 91-93 stangs wasn't to much more, I think they are about 225bhp. The main reason I would use a newer 5.0L is the fordged pistons and the MAF. Now you can convert a SD to a MAF but why do that if you can jkust install a MAF to begin with.
Now for the springs, some 5.0L guys run a 4cl spring to lower the car but if you want a stock highth car than yes you'll need some V8 srpings.
Ok now for this 8.8 deal. The SVO use a 7.5 and has done really good with them. If I ever plan to run over 300+ rwhp i'll consider a 8.8 swap but until then I'm not going to worry about it.

Well when I have like a grand or two that's the donor car I'm looking for then
Hell I wouod almost consider buying a Grand marque just to get a 5.0L if I was going that route. Now granted they have crap for heads but you can find some used GT-40 heads pretty easy I'm sure.

I thought with the 87 they changed a bunch of stuff :S
Now that puts me in the realm of less that 150k on the motor
thanks for letting me know

Here is what I found on the 86:
EFI with speed density air intake, dual exhaust, but more restrictive heads. The 7.5-inch rear end was replaced by the sturdier 8.8 inch. The compression ratio went up from 8.4 to 9.2:1. Horsepower was down in ’86 compared to ’85, but torque increased.
Last year for the SVO. A total of 10,000 were produced between '84 and '86.
Related Events 1986 For the first time since 1926 Ford's earnings were higher than GM's.
This is all I found on a 87:
1987
The restrictive heads were replaced and a bigger throttle body was added along with cam, intake and exhaust manifold changes to increase HP by 25. An air silencer was placed upstream from the filter at the cost of a couple HP. Compression ratio was 9.0:1.
Bigger front disc brakes. Wheels were 15 x 7 inches.
The car was about 180 inches long, an inch shorter than the original Mustang.
Base price for a GT was $11,300.

Ford is heavily criticized when it's learned they plan on replacing the Mustang with a Japanese-derived FWD. Ford recants, keeps the Mustang and renames the new car the Probe ( bet ya didn't know they was replacing the stang with a Probe
)
Here is what I found on the 88:
1988
In California the Speed Density intake was replaced by the "smarter" Mass Air metering. This improved drivability, emissions, and fuel economy, but with a slight drop in HP. Mass Air has better flexibility for moderate to large HP upgrades because the computer can adjust to modifications.
1989-90
Mass Air for all 5.0’s. A minor cam change to quiet the valve train cost a couple of HP.

Then here is the 91-93:
1991-92
16 x 7 inch wheels introduced in '91.
Generally, the '89 through '92's are considered the best for adding engine modifications. The combination of stronger block, MAF, better heads and forged pistons (pre-'85's and the'93's had cast pistons) make these easier to modify and more reliable.
Related Events 1992 400 HP Dodge Viper introduced
1993
The last of the Fox-bodied Mustangs. The published HP was now 205 though there was no specific change causing the drop, just an accumulation of changes from previous years and Ford decided to publish "honest" numbers. The GT-40 equipped Cobra was conservatively rated at 235 HP. A very limited edition Cobra R of 107 cars deleted A/C, the stereo and the back seat and added better brakes and a stiffer
suspension.
Base price for a '93 GT was $15050.
