I was wondering if a 5-speed transmission, clutch and bellhousing from a '64 F700 with a Y-block (probably a 292) would fit behind the 360 that is in my '65 F350.
I know there may be motor mount and trans mount differences but are the input shafts and bellhousing patterns the same or not? How about the flywheels? thanks for any help.
 RE: do FE and Y blocks swap? -- Dave Shoe, 03/12/2001
292s may have only gone into F-series up to 600, and B-series vehicles to 700.

The L302 or L332 looks a heck of a lot like the Y-block, except the oil filter stands straight out of the block instead of tilting down about 20 degrees from straight out on the Y-block. They are certainly of the same era.

They are called the 302HD and 332HD engines. I only stuck the "L" in front of them because I've seen the designation of "L332" in an industrial engine manual that Ford put out. Someday I'll get it sorted out.

The F750 got an L302, and the F800 seems to have gotten an L332. I wish I had time right now to scan for other hits.

 It's got a lot of the feel of a 390. -- Dave Shoe, 03/11/2001
The 410 is a quiet, smooth motor with lots of performance potential. It's not much different than a 390-4V, feel wise.

It does have the sacred 428 crankshaft in it, and lots of other 390-type goodies which make it worth building.

It may have the fairly common large runner C6AE-R heads, but it may also have the very common small-runner C6AE-U emissions head. Ford didn't seem to care which motors got which head. Either head will make good power, but the -R head can ultimately make more HP.

It sounds like a keeper to me. Just don't expect much performance "out of the box". Your gonna have to ditch the intake and cam assy to make any real power.

 RE: 410 4v fe -- RC Moser, 03/11/2001
I think the 410 would make a excellent motor for your 59 in stock form. I had a 59 with a 352 and it would lite the tire up for a block. (mainly do to skinny tires, rear suspension, and low end torque of the 352) Be kind of like you 352/390 on steriods. Mine had 155K on it and the bottom end is still standard bore. Other than the heads being off for decarbonization and resealed it's pretty much stock. I don't think you will be disapointed with it even in stock form.

Shoe, Im worried if I use the tall air filter the hood will not close on the car.
 RE: Tunnelport Questions?? -- Will, 03/11/2001
I have a 67 Shelby hood with a 67 Shelby intake (2x4). The standard oval aircleaner fits just fine. The 3" K/N filter almost fits. The top of the cobra oval touches the hood, but it closes just fine. It would probably work, but it would rub the fiberglass, and ultimately wear a hole (or make it crack).

I want to machine the cobra oval to take 1/4" to 1/2" off. It's plenty thick, so I think that's reasonable. I've also considered cutting the hood to give me an extra 1/2". I need to have the hood modified anyway, because it's warped a little. I saw a 67 Shelby in a mag several years ago, (I still have the article), where they cut the hood scoop and reattached it 1/2" or so higher. Sounds like a fun project.

So the bottom line... If you have a stock hood, you won't be able to put a 3" oval cleaner on your car. You may have more luck with a stamped steel assembly, because they're not near as thick.

I don't know how the height compares between your engine and mine, but I bet they're similar. I could measure mine if you like.

 RE: Tunnelport Questions?? -- Travis Miller, 03/10/2001
If I remember correctly, you are using the stock hood. That means you will have to use the short air filter element on the oval set-up. This is because of the height of the tunnelport intake.

A nice set of chrome pentroof 427 valve covers are hard to beat for looks. However there are some nice looking aluminum covers on the Shelbys. You might want to check them out.

The big discussion has been on what headers to use. There is no doubt that a set of Hooker competition headers would put out the most power when they are run open at the track. However it has already been mentioned that they do hang down a long way. While they may look mean, they do present a major problem when cruising on the street. Especially with speed bumps at the local hangout. When headers get dented, they look nasty.

Another route that can be taken is the tri-y type headers. These fit inside the chassis out of harms way. A friend of mine use to run them on a 427 with a tunnelwedge in his '67 Mustang. We were surprised that there was not that much gain when he switched over to the competition Hookers when run thru the mufflers. The performance picked up a little but it was not enough to offset the cost or the hassle of trying to cruise around with those low hanging things on the street.

The rods appear to have been lightened a bit while being balanced, as you mentioned the balance pads are ground down further than stock.

If the assy was rebalanced when the rods were ground, some metal would have tyo be removed from the front and rear counterweights to compensate.

Internal balancing is mainly only done to the rear counterweight in a 410/428 (non SCJ) because the front half of the crank is internally balanced at the factory. Internal balancing requires the ADDITION of heavy metal slugs to the counterweight, so if there is no evidence that the counterweights have caps welded to encapsulate the heavy metal, they have not likely been internally balanced.

If lightweight pistons and rods are used, however, it is possible to reduce the reciprocating weight sufficiently to eliminate the need for the rear counterweight. I doubt this is the case.

As it's a new motor and you'll probably want to get a buncha miles out of it, I'd pull it apart and bring the crank, rods, and pistons (with rings and bearings and flywheel) to a balance shop. Ask them to "inspect" the balance. It's a lot cheaper than actually balancing the assembly. This is also a great time to get a sonic mapping of the cylinder walls.

If all looks OK, then you can reassemble with confidence, and you'll also know what the guts of the motor look like, and also learn whether it was assembled correctly when you bought it. This is important when your mashing the throttle. If it's a little (or a lot) off balance, then you can pay the few extra bucks and get the job done right.

As for stock iron FE flywheels: They're rather brittle and dangerous. When running a stick with a performance FE, you really need at least a steel flywheel. A blowproof bellhousing becomes important as the power and revs climb from there. If you must run the iron, be sure to use a blowproof bellhousing.

 RE: engine balance -- Dave Shoe, 03/10/2001
Actually, it's likely the engine WAS balanced with a CJ flywheel attached, as you seem to indicate there are similar new holes on both the front and rear counterweights. This agrees with the rod modifications, and suggests there was a rebalance done...sometime in it's history.

The problem is you don't know whether the flywheel was slightly rebalanced during a prior rebuild or what the flywheels history was. It may not have been a factory balance any more than ANY well-used 30 year old flywheel might be. Also, you really don't know whether the rods and crank were rebalanced in the same motor - the parts could have come together from anywhere and never actually balanced as a system.

$300 includes disassembly, balancing, and some reassembly of components. If you supply the loose parts, it's much cheaper than that, and you'll probably reassemble your motor much better than the shop has time for.

If you're gonna go fast AND be reliable, you really do have to know your motor well. Stuff breaks when you push it, and it's nice to know enough about your motor to anticipate problems before they occur. You can't "anticipate" problems unless you have a mental view of what's going on inside the engine to begin with.

What's more expensive: Checking things carefully now or tossing out a blown motor and buying a used Saturn?

Heck, I can give a better example than that! How about: Checking things carefully now or blowing an FE engine and replacing it with a 460 crate motor?

Yeah. That hits the spot.

I have a set of N.O.S. Ford Muscle Parts pistons that are designed to bolt Cobra Jet heads onto the 390 and maintain 10:1 compression ratio. They are new in the boxes and include wrist pins. They are FORD PISTONS designed to improve performance with Ford off the shelf parts. I also have the from the muscle parts program, the literature for all the different factory parts they made to hop up the 390 $100.00

 RE: 427 cyclinder wall thickness -- Dave Shoe, 03/09/2001
It's wise to sonic test prior to boring, as this gives you the option of "offset boring" if the engine shop supports that kind of machine work. This sometimes let's you choose a smaller bore.

Core-shifted wall thickness in the "reinforced" square-cast 427 cylinders can be as thin as .090" (if I recall Ron Millers post correctly) because the bulk of the head bolt stresses are handled by the heavy cylinder sections, leaving the thin sections the single duty of constraining the piston. The corners will still be around .250"+ thick.

You can make a 427 .040 chevy piston work. I think the number is L 2300 F
