The intake cams are different, but the exhaust cams are the same. The Mark has a standard 6-bolt cast crank and the Cobra is the 8-bolt steel crank. Also the 93-95 Mark had a weak valve spring, but all the 32V got the "Cobra" beehive in 96 and they can be used in the older engines as long as you use the correct retainers. Also the Cobra used a high-volume oil pump and windage tray, but those items along with the stock Cobra oil pan are available pretty cheap from Ford Racing yet. IF you can find a complete Cobra intake for $500.00 it is the way to go. Mike
Engines with "P" heads did not start production till 11/6/96. As all 96 Explorers and very early 97 Explorer/Mountaineer had standard GT40 heads with 1.54 exh valves and 3 hash marks with 65-66cc chambers. The same head as the Cobra, but the Cobra heads had the thermactor passage drilled and were milled 0.030 for 61cc chambers. The "R" used the Lightning head which had 1/2 head bolts and not milled for 65.5cc chambers. The P heads were never planned for a Mustang, as they did not start on them until after the last run of push rod Mustangs were being built. The P was made to keep the Explorers clean into at least the 2000 model year, as the standard headed ones were only clean enough to meet 98 standards.
Now that we are talking Cobra Jets, here is our 70 "Q-code"Mustang. My dad bought it in 1974-5 with no motor or trans. It was owned by Ford Motor Company of Canada and used along with 3 other cars to hold drag clinics at dealerships and race national events on the weekend. In the winter of 70/71 Ford cut the funding and sold everything, and at that time a local racer bought it as a turn-key Super Stocker and raced the great lakes area for a few years before using the motor/trans in a 69 Convert. When my dad heard about it being For-Sale he bought it right away being the car only seen 3 miles of driving before being built so it was still like new. At the time he had 69 Mach that he used to get the car running and has only put about 2000 miles on it 32 years.
That is Great! I have been in contact with the "Pure Stock" and Factory Appearing guys for a while trying to get the "new" muscle cars in, but always get slapped down. I even went as far as to only allow up to end of the carbed era, but still no way. Not to sound negative, but I would still like it if the "whole" car had to look factory, ie no engine swaps of different engine familys, headers, no power adders, no aftermarket intake and heads, wheels ect...... My plan is a 85 Mustang 5.0 no option coupe that would look 100% correct, but have a 331 under the ported and milled E5AE heads with a reworked 4180 carb.....
Hi, I have been so bored today I was able to find some spring info some would be interested in. This info was from around 86, so I don't have the specs for the 87 and 88.
Stock Turbo Coupe with front code 1 is tag TAA that is a 425lb/in with 1750 load rate, code 2 is tag KAC that is 425lb/in with load rate of 1836. The rear code J with tag JAD that is 200lb/in with 963 load rate, code 3 is tag LUK that is 200lb/in with 912 load rate. Those were the most popular springs used from 83-86. The rule of thumb in chassis engineering was every 150 lbs in load rate subtracted from the factory selected springs the front would lower it 1/2" in the front and every 50lbs of load rate subtracted from the rear would lower that 1/2".
Spring set M5300B is tag MOG that is 435-530lb/in with load rating 1635 in the front and tag MIB in the rear with 200-300lb/in and load rating 587. These are production springs from a 85 no option Mustang V8.
Spring set M5300C is tag SAD that is 650lb/in with load rating 1461 in the front and the same rear springs as the B set. The fronts are production 84-85 Police/Taxi LTD front springs .
Spring set M5300D (for the Thunderbirds) used the front springs from the B-kit with tag MIN in the rear with 200-300lb/in and load rate of 732. The rear springs are production 85-86 Mustang GT Convertible units.
The HOT set-up was never offered for the Birds because it required Konis or Bilsteins to control the rebound, and at that time most people just reused the production shocks and struts. Using these springs with the production units made the car handle worse than the stock set-up. Those springs were the fronts from the C-Kit and rears were tag # CAZ 251lb/in and load rate 810 used in the 84-85 LTD LX. It lowered a stock TC or V8 about 1.5" all around.
That rear spring CAZ has not been in production for about 15 years and carried a service part# E3BZ-5560-C. The closest I have found is for a 99-04 GT that is part# XR3Z-5560-BA with 210 lb/in and load rate of 798. I will be installing a pair of these along with some the C fronts this spring using a pair of 03 Cobra front struts and pair of NOS rear T-Bird Bilstein shocks.
It is a earlier 85 built Jan 9 85. It has 35's in it with a E5S VAF, PK1 EEC, square intake with only the knock sensor provision in the front corner of the lower intake, water cooled turbo, 9" rear brakes, and external fuel pump. Now my friends 85 was built in Apr 85, also a automatic, but had single fuel pump and provisions for both knock sensors in the lower. His car was a high-level option car (dual power seats, headlight group, keyless, corner lights, anti-thieft, sunroof and of course cruise, tilt and int. wipers), but no leather, EQ, or ETC. That car had 15's on it. My sister also had a 85 automatic with the "standard" group options (no corner lights, no headlight group, no pass power seat ect) and also had 15's on it. I think those were the only 85 automatic cars that were around here, all the others were 5-speeds. Now for some reason I have seen ALOT more 86's having autos and only seen one 84 TC and one 84 XR7 with autos.
The 14" were standard on 83-84 TC's with the TRX being optional, and the 8-hole optional on any 84-88. What I am finding interesting is that the big news for 85 was the standard 15" wheels with Goodyear Eagle VR60 Gaterbacks, and every new Turbo Coupe I seen since Oct 84 had 15's. Also all my literature shows the 10 holes as being standard and the only wheel on 85-86's and only available on the TC except for the 30th Anny.
Hi, I am researching a 85 TC, the car was a mid-option (auto, dual power seats, power windows, cruise, premium sound, headlight group, cornering lamps, tripminder, keyless entry, and leather) that was a Ford "district rep" car for 1985 in California. After the 85 model year his neighbor bought the car some how. Anyway in 88 the neighbor sold the car to a guy in the Air Force stationed near Yuma City CA. In June 1990 he returned home to Michigan and sold the car to a friend of mine to buy a Jeep. My friend has had the car ever since (has never seen rain or snow and not been plated since 95) but found some very odd things about it. When he brought it home I found it very odd it had the 8-hole 14" wheels instead of the 15" 10-hole and it had hood springs just like a 83 Elan I had. So we figured the wheels were swapped at one time for who knows why, so he put a set of 10-holes on it. Well now he just got a History 999 report showing the car optioned with P215/70HR14 tires with Aluminum "sport" wheels. Also to prove the original "Ford Employee" tie, it does have 89 DSO and also he has a old Oasis print out showing the "in service" date 3 days after the "build" date. Just though some would find that interesting.
Here is my 85 F350 4x4. Complete ground-up restoration, converting a 2wd F150 into a 4wd 1-ton using 1 California truck, 1 Arizonia truck and about 5 others for other parts. Every wearable part is new Ford or N.O.S including all the body side mouldings (not yet installed in the picture), weatherstriping, lamps, all chrome parts ect.......... Fresh 460 with about 375HP/500TQ, built C6, Dana 70 rear (3.54 open in picture, now 4.10 pwrlok), Dana 60 King-Pin front, Alcoa wheels with 35" Toyo AT's. From a dead stop a "bolt-on" 94 Lightning with jump ahead until it gets traction, but by 1/8 mile it pulls the Lightning by 2 trucks, and by 4 trucks in a 1/4 mile.
