Remember, no expensive engine stand. Just am ol tire and let her rip, listen for bad things and oil pressure. Then put it in the car and drive the PI** out of it.

Looks like a raised deck 41 engine. Did 42s also have a raised deck?

That's an 11in. clutch flywheel, your not putting that engine a 5 ton dump truck are you?

No Walt it's not going in a 5 ton dump truck. The person I bought it from told me that the motor came out of a delivery truck. Any advise on the flywheel before I put it on the motor? I want to use a T5 trans with this and I do plan on dropping the motor in a modal A frame.. Thanks

If using Ford parts, consider running a cut-down Ford flywheel and a 10" clutch . . . or even a performance oriented 9" clutch (as they do rev nice and fast). Since you're going to be running it in a light car, you can decide whether you'd like to run a steel flywheel in the low to mid 20 lbs weight range or even go to a lightweight aluminum flywheel (which are just plain fun in my opinion). If you're buying "new", there are quite a few options out there - comes down to brand and money spent.

I'd checkout RAM Clutches - they have specific flywheel and clutch combinations for T5 trans, top-loaders, etc.. You'll find they have flywheels for 39-48, 49-53, aluminum/steel, etc.. You might want to talk to their tech departments.

Let us know what you find.

I would vote for the aluminum flywheel and 9 inch clutch combination. Rotating mass and acceleration are related!! LOL

I'd have that flywheel redrilled for a 9in. clutch, you can also have that wheel lightened to about 20# and balanced, I get my clutch and PP from Fort Wayne and have them install stiffer springs in the PP. Walt

Was wondering, why is the 9" clutch preferred over the larger one that came with the this 39 motor? Is it a weight issue, performance thing??? Any info to educate me will be appreciated..
Thanks

Performance as in acceleration. The issue is rotating mass and the distance from the centerline. You want the rotating mass as small as reasonable and as close to the centerline as possible. Something like the demonstrations of the skaters moving their arms in and out to increase and decrease rotating speed. A small amount of weight further from the centerline will make a difference in the ability of the flywheel, clutch plate and pressure plate to accelerate. The assemble should be as light and close to the centerline as possible but it is also dependent on the vehicles weight and gearing. A light car with low gearing likes a light rotating mass. As the car/truck's weight increases or using higher gear ratios, more rotating mass makes driving easier (less likely to kill the engine and/or have to slip the clutch to get it going) but acceleration suffers. Like everything it is a compromise.

Couldn't have said it any better - exactly right!
