Easy thing to check by looking at the front of the rear axle assy. 8 and 9 inch rear ends have removable gear carriers. If you can put a 9/16th socket with a 6 inch ext straight on the bottom 2 bolts for this carrier, it should be a 8.A 9 would need a flex socket.

All 68 mustangs had the 8" rear,unless they had a 390 or 428.

This is all the rage down here. A Mate Of mine goes to all the swap meets with Tappet covers and hubcaps and yes he has just started doing timing covers filled with clocks...:^o

I have to admit.... I do have an FE Tappet cover with a barometer and clock in it> :^)

so I cannot say what model, light duty or heavy duty.

is that a o or a c4ae c 4ae, if c 4ae 1964 heads big ports on the intake side i like to use the pre 65 intakes that have the same size ports i, like them i use them on the hotter projects thay have a 500 to 1000 rpm edge over 1965 and newer non hp heads.......with the smaller ports.i try to save all the pre 65 stuf i can find,,,,

They are a common but decent head that will accept CJ size valves. They and the C6AE-R can be made into "poor mans CJ" heads. I'd keep 'em too.

Stock convertor is what I plan on keeping. The build is basic. 390 with headers and performer manifold and holley 650. I am looking for a cam that will give me more torque because I dont want to go over 5000-5500 rpms. The rear end gear is a 390 something. So I would like to know if this 270H will make it snappier and not slower than it is now, or should I go to a milder cam from 800 rpm to 5500 area.

is your car a mustang or a heavey weight ltd ect i,d use better springs than stock.and better pushrods .and the one pice retainers .i like comp cams thear cams work.

What transmission and rearend gear ratio will you be putting behind this monster?

Save some money on the bottom end and use the cast crank.Cutting down a 391 crank is an expensive way to go.Magna flux and blueprint your stock rods and use ARP rod bolts.With a lite weight piston,and cast iron crank it will take a lot of power to hurt it,and it will turn6500+rpm.425 or 450 horse is a reasonable expectation for a streetable 390.

Good choice on tranny and rearend gear. Be sure to budget for both of them from the start. A lot of projects such as yours seem to run out of money with the engine and never get a good drivetrain behind it. Without a good gear like a 3.50 all the money you spend on the engine will seem wasted when it comes to performance. In other words, with the stock gear (2.75 or 3.00) the car will actually be slower in the bottom RPM range because of the higher torque range brought on by a larger cam and better flowing intake manifold. The 3.50 gear will get the engine up in the useable torque range quicker. Your car needs horsepower, strong tranny and a good gear to be a true performer. Leave out one of those items and the result is a disappointing ride.

If your planning on serious ground pounding I'd go with the 31, although I have a 28 spline setup in my car now and it has survived many holeshots, although I never had any tires that hooked up at all, same year mustang with a 390 and 4 speed and N2O. I snapped a driveshaft once, but the rearend held together which still amazes me since it is just a 2 pinion traction lock with 3.91 gears. I think a locker will be a little harder on the parts.

Yes that's a fabulous deal! To find a '64 two-door with any FE and a factory stick shift is ...... I'm just kinda wordless. Only $250 ..... jump on it this deal. Don't procrastinate.

yes i,d by now.

Hey Dano it might be helpful if you included some specs with this cam.

You might also check the March 2004 issue of Mustangs and Fords. There's an article featuring a 428 rebuild where they've selected a Crane hydraulic roller part # 34HR00012 Grind # HR-210/294-2-12. This cam may be just one step milder than the one you're considering.

Hope this helps to get the ball rolling on some responses for you.

Jegs part number 170-904FEB $316.99, or here is a link to summit racing, looks like they have a couple different ones for the FE
