Welp, just in case they are too busy, or some of the other Fox guys are too busy (we don't get a ton of traffic here...not like Sam's place or the Classic's) I'm gonna get ahold of my buddy who knows a lot more than me...which is easy to accomplish 'cause I don't know much! LOL.

Hopefully he'll have some answers for these questions...I'll let y'all know ifns he does!

Stewart

He did have a great idea though! This is for you too, AJ.

Go to www.Mustanggt.org and post on their tech board (it's not a UBB type site, but it's easy to figure out). Address it to Kathy Bowers (web administrator) and list as much info on the engine as you can.

Please don't email her the question. Post it on the board.

Scott is a member there from southern California that may be able to help you too, but at the very least, I'm sure your best bet and source for info would be from Kathy Bowers.

Kathy and David Bowers have obtained a huge resource of information for the Fox Body GT Mustang, and are a fantastic source for information.

I used to post there, but I needed fellow crazies to keep me company and I found them over at Sam's Place!

Stewart

PS - Let me know if she's able to help!

The 4V was introduced in 1982, but I don't think the dual snorkel air cleaner happened until 1983. It ran until 1985.

The worst heads are 1986 Mustang heads, (EFI).

The 1985 engine will have a roller cam and a 351W firing order. 1983-4 engines have a hydraulic cam and the old 289-302 firing order.

In 1985 all automatic equipped cars had CFI, so if it has a auto trans flexplate then it can't be a 1985 motor.

As far as telling whether a 302 is roller or not, just check under the intake for the lifter retainers, all roller motors have 'em.

Ok, now this motor and all Ford motors will have casting numbers on the pan rain on the passenger side of the block. That will give you an idea of what year it is. The block with probably be like a E1ZE-6014-BA or something. This means the block is an 81 model block. If you pull the valve covers, there will be a casting number in the middle. Sometimes it even says 83 302 or something of that nature cast right into the head. This hopefully will help you in learning what year the motor is. If it has a stick flywheel on it, it for sure is an 83 to 85. First year for a 4bbl holley was 83. Stick only. 1 other shot is look for a tag on the valve cover. that might give you the year of the motor due to emissions things.

Hope this helps!

Its actually the '85 and earlier blocks that are different .

Actually, the 82 HO motor still had a 2V carb and intake, though it was an aluminum intake and the carb had a slightly bigger cfm rating than the 79 5.0 engines (which had a cast iron intake). The 4V was introduced in 1983 and was used to 85. {Oops, I see this was corrected earlier... sorry!} Also, the 82 HO engines did have the dual snorkel air cleaner.

Yup, 85 was the first year for the roller cam, but the 302 HO went over to the 351 firing order in 82. So, all 82-85 HO engines have the 351 firing order.

Roger, it sounds like you have found an 83-85 HO engine, and for $100Cdn GRAB IT!! The intake and carb are worth more than that, and if it's an 85 the roller block has value too. Matter of fact, I would be interested in that intake and carb set-up if ya want to recoupe your $100 investment.

Hope that helps a bit!

Heh heh heh....that "buddy" has finally joined the site and answered in person!

'Bout time, Mike! (Fishtail)

You and Ian (and a few others...Scott, Jim Signorelli, etc) were always really good sources of info on the GT board.

See? I told you he knows a lot more tech than I do!! LOL

---

I think that they originally revised the 302/5.0 block in 82 as well. Up to and including 79 they were still using the thick wall casting block from the 60's. The 82 block went to a slightly thinner wall and shed a few pounds in the process. That's why it's not recommended that you bore a post 79 block 0.060" over (0.040" max, if I remember correctly).

You are definitely correct about the change in 85 too. I believe that they beefed the block up a bit (but not back up to pre 1980 levels) for added strength, and raised the height of the lifter bores to accomodate the taller roller lifters.

Geez, ain't all this fun!!

Give us an update when you get a chance!

If it is it may be a 302 from a Mustang GT
1983-1985. The 85 has roller lifters and forged pistons.

thanks, roger in toronto, canada

Hi Roger! Boy, this is some little mystery isn't it. It will be hard to tell the year from the carb as the same carb was used from 83 to 85, I believe. In order to see if the engine has the roller lifters you are going to have to pull the intake manifold and check in the lifter valley. By pulling the valve covers you can only get a good look at the rocker arms, and they were just stamped steel units for all of the 82-95 HO 5.0s (except for the 93-95 Cobras which used cast roller rockers).

If the engine has cast iron exhaust manifolds it is either an 83 or 84 motor, which are pretty much exactly the same. If it has production tube headers then the engine is from an 85, the first year for the headers from the factory. From one of your earlier posts it sounds like it has the cast manifolds, so it looks like we have narrowed it down to 83 or 84. The E3ZE designation on the back of the intake manifold (and the E3ZZ on the exhaust heat sheild) indicates that it's a 1983 piece, but those parts may have just continued on into 84 and 85, as the manifolds didn't change over those years. However, the 84 HO 5.0 had a revised choke design which eliminated the use of exhaust manifold heat tubes, so check that out. If it has the tubes to the choke it's an 83, or if the tubes are not in place, and the exhaust manifold has no provisions for the tubes (on the passengers side exhaust manifold, I believe) then it's an 84 HO 5.0! Hopefully this will clear up the mystery once and for all!

As for the "Twister" designation... I've heard little rumours floating around with regards to a few GTs getting the Twister designation for a dealer down in Kansas (or somewhere like that). The original "Twister Special" was made in 1970 as a dealer-specific special down there in the Kansas area. They were basically 1970 Mach Is with a grabber orange paint job and special Twister decal package, and either the 351 CJ-R, or 428 SCJ-R. I haven't heard anything concrete on the late model Twisters, so I can't tell you how rare they would be, or even if they actually existed. If you can locate the original body and get the VIN and door tag data I will be able to tell you more.

Either way, you got a great deal on that engine Roger. Way to go!! Keep us posted on anything else you find, but hopefully this will solve the mystery. Please let us know what the final call is on the year, ok!

I'm impressed.

Also, for the record, Cobra motors came with Aluminum roller rockers, not Stamped ones as earlier noted in the post.

Roger, You donot have to pull the oil pan to grab the casting number of the block. It will be on the passenger side, near the rear of the block, just above the pan rail. It should be either a E2ZZ-A or a E5ZZ-A. If its a E5, then we know for sure it is an 85 motor.
