| Transmission problems on my horizon? -- colette, 04/24/2006
Hello I'm a single mom and I have a 1999 35th anv.Ford Mustang Gt It's at 122,000 miles and i've taken good care of it, but as of late its been riding kinda rough like my rpms is off and when i reach 200-400 rpns it seems to stick for a sec. then kick up and back down real fast followed by a mild jolt/jerk/shake for a second and the ride smooth for a little while until i speed up all of a sudden or have to slow down real fast. I thought it may be transmission problems. I had recently had a tune-up new radiator and oil change and my fluids topped off... Any help would be much obliged for that i would hate to take it to a shop and get screwed because of lack of knowledge if its something like a vacuum hose... Thank You. my email is Mescaline420@ aol.com. Sincerly Colette |
| | Sounds like the torque converter clutch. -- Gerry Proctor, 04/25/2006
Honestly, it would be wise to get the car to the dealer for a diagnostic. I do not recommend a transmission shop, like AAMCO, since they are in business to sell transmission repair and they make no money if you don't have a transmission problem. A dealer service department has no interest in selling you a trans repair that you don't need.
It may be nothing more complex than a software reflash to take care of the problem.

| Holley Carb problems -- Bob P., 04/23/2006
Has anyone had trouble with the plastic floats in the holley carbs? Bought a new carb off Jegs awhile back. The secondaries seem to stick and flood the engine. I take it apart inspect everything looks good put it back together. Carb works good for a while then the same thing again. Just took a brass float out of an old holley and put it in hoping that may help. Any thoughts about this? |

| 9" differential lube -- Dan Williams, 04/22/2006
I have just reassembled a 9" limited slip differential after inspection. When I went to have it filled and add the additive for this type of differential the people at the garage did not know what kind of gear oil to put in since it was too old for their computer to have that information. What is the proper oil for this type of rear end. There are no tags on the unit to ID it. |

| 390 Service Block -- Lee Griffith, 04/21/2006
I picked up a 390 block last weekend to build and have learned that it's a "Service Block". Can somebody tell me what that means? Thx!! |
| | Nothing special. -- Gerry Proctor, 04/24/2006
A service block is just a block that had no target vehicle. Used in over the counter sales, warranty replacements and the like. It's no different than a 390 block intended for the assembly line for a target vehicle. |
| | | I would question calling a 390 a service block -- Hawkrod, 04/24/2006
The term service block is usually reserved for engine blocks made after production ceased for passenger cars that have marked differences from the earlier blocks. Such as 427 and 428 blocks cast in the 70's using the later 360/390 pickup style block skirts or 302 boss blocks with D1Z casting numbers. What makes your 390 a service block? How is it different than a regular 390 block? Hawkrod |
| | | | I don't know if you call them service -- Lou, 04/24/2006
blocks, but Ford had a fire sale on 390 crate engines around 1978. I pick up 2 at a really good price from M&E Ford in Meriden CT. |
| | | | RE: I would question calling a 390 a service block -- Lee Griffith, 04/25/2006
The block has no casting number. The date code is a symbol - a line with two dots at the bottom and then F23, there is also a "W" stamped abote the date code. In addition, the block has a series of ridges on each side. |
| | | | | None of that makes it a service block -- Hawkrod, 04/25/2006
Look at that date code again, that "line" is a 1 so it would read 1F23 and that would be 1971 June 23 which would likely make it a 1972 engine. The two dots are something that Ford started doing in late 69 and did through part of 72 or so to make it appear different from 59, 60 etc... the two dots simply denoted the second time that date code sequence was used on that style casting. Most 68 - early 72 blocks do not have casting numbers and most 71 and newer blocks have the ribs so it really sounds like you just have a very late 71 or very early 72 truck engine. Hawkrod |
| | | | | | RE: None of that makes it a service block -- Lee Griffith, 04/26/2006
Wow! I had wondered if the first symbol was a one...the reason I questioned it was that the stamping of that symbol did not match the "F23" at all...much thinner and taller - with the two dots. I had found online a photo of date codes on a 390 and has noticed that the all stamping matched in size and type... Thanks very much for the info!
Now, what is a service block? Thanks again Hawkrod! |
| | | | | | | Well, on a 390 I am not so sure there is one.... -- Hawkrod, 04/26/2006
In the hobby, a service block is a block that differs from a regular production block or was made after production ceased. If your block was a 428 with the same characteristics it would be a service block because none of the production 428's were ever made like that so it is different than what was used on the assembly line on a 428 car. Because the block you have is what Ford used at the time it was made it is no different than a production part and so even if it was sold over the counter you would not be able to tell the differnce between it and one used on the assembly line.

| T-bird 390 -- Mike, 04/21/2006
I am a complete novice when it comes to engines.I have been working on my 65 Tbird body for a long time now and want to be sure that when the engine goes in it makes it all worth while.So the question is I have a stock 390 and am going to at least rebuild it new seals,piston rings,main bearings,and that is about it.Would it be worth/ possible to swap in 428 heads and leave the rest intact?Also would a performance intake/exhaust be a better/wiser move?Any help or suggestions are welcome. |
| | What kind of 428 head? -- Gerry Proctor, 04/21/2006
The only 428 head that is a step up from a 390 head is the 428CJ head (C8OE-N casting typical). All other 428 heads(or better, heads that were on a 428, since there was only one 428 that got a distinct head, the CJ) are the same as heads used on 352/390. If it's not a CJ head, then you haven't moved the ball down field at all.
As to whether it's worth it to install even a CJ head on a TBird depends on what you expect. Unless it's part of an exhaust, cam, and intake upgrade, I'd say probably not.
As to other issues...a good free-flowing exhaust is always going to be your best bang for the buck. Doing anything else before you do the exhaust is usually not worth while. |
| | | RE: What kind of 428 head? -- hot428ford, 04/21/2006
I think installing a set of 2.09 intake valves off ebay for 100$ is the best thing going ..Your going to rebuild the heads anyway?? With a good exhaust, intake and little hotter cam you easily have over 300 HP. LET THE GOOD TIME ROLL> |
| | RE: T-bird 390 -- Beganit2, 04/22/2006
Beganit<-----newbie!! hi all
I'm a Ford freak for ,dang,35 years now. Ive had a lot of stuff and still have a lot of stuff.
My point is, from my visual inspections, 427 low riser, 428CJ, and, the important point, 390GT heads look the same to me from a port size point of view, the differences are valve sizes,combustion chamber volume, and exhaust bolt patterning. ( the 390GT's has smaller chambers and valves).
there could be more but I dont see them.
P.S. I still have the 390 heads if anyone is interested. |
| | | RE: T-bird 390 -- Mike, 04/22/2006
Alright,so I'll keep my 390 heads improve the exhaust w/ flowtech headers and bigger pipes.I saw some valves online and a camshaft but it is all greek to me so if you guys can give me the cliff note version of how this works that'd be great.Specs on valves were 2.09 intake and 1.65 exhaust and this means nothing to me.The cam I saw had several choices and had descriptions of power at ranges i.e low end, mid range but the listing also referred to a lope does that mean a rough idle? |
| | | | T-bird 390 -- hot428ford, 04/23/2006
The cam specs from the major companys will tell you the lift & duration needing for the RPM range you'll be running . You'll need to decide the rear end gears and if your going to a manual are auto trans and what stall speed if you chose an auto .With my 4:11 rear end and a C-6 with a 3500 stall I'm running a 522 lift, 300 duration,71 degrees overlap ...Its very close to the cam offered for a 429 boss ...Ford offered a #C3AZ-6250-K for a 427 w/auto trans it had .525 lift , 290 duration , 78 overlap, and put out 425 HP ..The cam needs to match with all the other parts including the weight of your ride ...hope I could help.. |
| Big block timing questions -- JR, 04/21/2006
I am building a 460 it has flattops weightmatched rods std bore with an edelbrock perf rpm cam i am using the edelbrock recomended timing chain and i was wondering about advancing the cam the 4 degrees on the cam if there is some ill efeccts on the motor or if thereis something eles i have to do i am goin with the edolbrock perf rpm intank also and i am gasket matching the heads intaks and headers im not sure what size carb to run 800cfm i think any input |
| | Why do you want to advance the cam? -- Gerry Proctor, 04/21/2006
There is only one reason to alter cam timing on an unfired engine...to bring the specs in line with the cam card.
If you want to advance a cam on an unfired engine because of something you read somewhere, you're taking advice from the wrong place or you bought the wrong cam.
There's no ill effect on the engine. Advancing the cam will close the intake valve earlier which tends to increase lower rpm power to the detriment to higher rpm power. You would only need to know this is what you want once you run the engine and drive the car to reach that conclusion. Intalling the cam straight up may give you exactly what you're want. You never know.
800 cfm is fine for a 460. |
