Looking at putting a new throttle body on my 88 Vert. Was looking at a 70mm TB, but I have a guy who has a FSM 65mm TB for a pretty good price. Any advice?

I have a 65mm on mine. It has very few mods right now, and even when I finally get the Edelbrock heads, intake, and E cam, I'll still stay with the 65mm.

With everything I've read, there was either no difference, or very little difference between the 65mm and 70mm TB on a N/A engine. When you get into power adders is where you will need to address anything bigger than 65mm for the street 5.0 engine.

Stewart, thanks for the info. Here is what the guy said on this: mailto: "you'll just have to enlarge the opening of
the intake so you don't have a ledge,stock size is 60mm. Stuff some rags in
the intke and use a Dremel to open it up" Does that sound about right? The guy wants 150 for both the TB and spacer.

Hi Tim
$150 is a good price for both the spacer and TB. I have a brand new in the box edelbrock 65mm tb for sale at $190. I would not take the time to dremel the stock intake. the little ridge is not a big deal. If you were using aftermarket heads and large camshaft and so on, then thats a whole different story. When I drove my Capri on the street, knowing an 86 Intake is small compared to a later model, I didnt alter the intake, and I ran 13.40's with slicks, open exhaust, 4.10 gear, and traction bars. =)

Look very close at the parts before you make the purchase.

Like Tony said, it matters, but only when it matters. LOL! Hows that for double talk?

For your application, much like my setup, it doesn't affect the performance enough to worry about. Besides, I'm sure you'll end up getting an after-market intake soon enough.

I keep wanting to purchase the C&L 76MM mass air meter and aluminum tube, calibrated for the stock 19lb injectors, but darn it all if I never can seem to scrounge the cashola together!

It sure does look nice though, dudn't it?

Looks real nice. Wish my engine looked that good. I thought about going to Mass Air, but I think I will leave it speed density for now. Just going with some simple mod's (Cheap) for now. Looking at installing underdrive pulleys, 65MM TB and a BBK Cold Air Induction. Thought about changing my gear ratio, what would you recommend?

Well, I have a T-5, and I'm about to put in a used set of 3.73's that I received from a very sweet, beautiful and wonderful M&M member for free! But if I hadn't received those gears, I was going to go with a set of 4.10's.

A lot of people are concerned with gas mileage...as am I...but the way I look at it, I own a Mustang. If I wanted gas mileage, Ida bought a friggen Escort. Not only that, but if I don't put my foot through the floorboard, then I get a lot better gas mileage than if I do lead-foot it.

Everyone will have an opinion on R&P gears. If you have an automatic, I've heard you should go no less than 4.10's. With a T-5, no less than 3.73's.

4.10's huh? I am not too concerned about gas mileage either. She ain't my daily driver. She is my project and hobby. Are the gears pretty easy to change or should I get it professionally done?

If you are Alex or Tony, then I'd say It'd be easy as pie for you! But since you're more like me than Alex, let a pro do it!

Lotta gearheads working on their own cars will tell ya patience, the right tools and equipment, and proper directions will see ya through. But when it comes to rear diffs and tranny's, I prefer to let the pro's handle those.

3.73's and 4.10's are weak. Go with a 4.88!!!!!!!

Honestly, I would say no more than a 4.30 in a stock 5.0 deal. And thats with a healthy camshaft and so on.

If you want to convert to Mass air, I have a kit in stock to do so. What it is basically is a cobra mass air meter, computer, and brackets and hoses. Its not cheap either!!!!

Wanna get crazy? We can put a combination together for you and make that thing scoot with the stock intake and heads!

Basically want something that is gonna get some respect Not trying to be a Cobra Killer or anything. I am always open for suggestions Capri. If I put 4.10 gears in it, will I be alright on the interstate? I heard from a source that it may cause problems with RPM's and such. Trying hard to manage my money (what little I have left)

That's why I said "no less" than 3.73's/4.10's!

Pssssst, Tim...listen to Tony. I wish I knew half of what he and his father Alex have forgotten. But do remember this, he and Alex speak from a racing perspective and point of view. Sometimes they.....well, for lack of a better term...sometimes they forget they are talking to and teaching mere "mortals" like us!

Don't worry about your freeway RPM's. You'll get used to them being a few hundred RPM's higher at speed. Of all the UBB's I read, I've never read where someone wished they had gone to a numerically lower gear over the actual gear they choose. In fact, many wish they had gone to a numerically higher gear!

Yup, guys with 3.55's wish they had gone with 3.73's, guys with 3.73's wish they had gone with 4.10's, and guys with 4.10's wish they had gone with 4.30's! And a lot of guys that went with the 3.55's, jump straight to the 4.10's.

As a regular member over at the Corral always say's, "don't fear the gear!"

Did you get some price quotes? How much were you quoted? Was the quoted price for the labor and parts, or just labor only?

$360????????? Ask them if that includes parts. That sounds about right then. If not, tell them to pound sand. I do a rear end install for $200-250 depending on what I need to do.

The milage thing. That depends on you. If you dont mind burning a bit of fuel to go faster, then you are good with either 3.73, 4.10 and 4.30's are pushing it. The rpm range with a 4.10 gear and a AOD auotmatic is 75 mph at about 3000 rpm.

Honestly Tim, If you are intrested in a package to run quicker, just send me an email with what you want to do and Ill see what I can put together. If you have a budget in mind, include that also. Mild to wild. I have a Camshaft in stock and other things.

I am looking at installing my 65MM TB this weekend. Anything special I need to get other than the gaskets?

Thanks

It's pretty straightforward, Tim. I've never installed a new one but I've had mine off a couple times. If you have to pass emissions in your state, make sure you punch out the necessary perforated holes in the gasket to allow for proper emissions. I had a buddy put a bigger T/B on his 5.0 and he forgot to remove a perforated hole on the gasket and subsequently, he didn't pass emissions. Once he took it apart and punched out the hole, he was fine.
