Thanks, Ed. I have to = admit that I=20 am still not certain that I understand everything I need to know = about the=20 flex plates, etc.

Hi Paul,

Maybe I'm missing something, but why do you = need to=20 know anything about flex plates for your engine swap? Aren't = you going=20 to install the Ross drive on the new engine? If so, = wouldn't=20 you also move the Ross drive plate (with the springs) and = or flex=20 plate at the same time? I just don't see why = you need=20 anything new.

Hey, Rusty....yes, I would install the = Ross drive=20 on the new engine, along with the Ross drive plate that has the=20 springs. I just thought if I had the proper flex plate, it = would be an=20 easier engine swap if I just have to remove and reinstall that = triangular=20 looking plate with the springs. I understand that is the drive = plate. What the heck is the flex plate....are we talking about = the=20 cast iron flywheel? That is harder to exchange, because of = that large=20 2 1/8" nut . If I just have to remove and reinstall the = triangular=20 Ross drive plate that has the springs, and it will bolt onto the = flywheel of=20 the standard transmission engine, then I am all set.

Paul,

1. There should be no reason why the = flexplate=20 (to which the triangular thing with springs is bolted) you are using = now=20 should not work.

2. You do not use the flywheel which = is a very=20 heavy (like 25+ lbs), the flex plate is similar in size = but not=20 thickeness. Its stamped out sheet steel and has the ring=20 teeth welded to its outer perimeter. If you have to grunt to = pick it up=20 then its a flywheel {:>)

3. As best I recall you can remove the = triangular piece with the drive spline without removing the flex = plate (its=20 held to the flex plate with 3 bolts) - however, that does require of = course=20 that your new engine have the flex plate mounted. You can not = mount=20 the triangular piece on the flex plate before mounting the flex = plate to the=20 engine because then you have no access to the flywheel nut that = holds the=20 flex plate.
