Hello
I have a 511B1 motor
It has a Keith Black top fuel crank 4.25
I'm looking for ideas or if you guys did this how do I use my 727 Tourque flight to work together
Meziere sells a flywheel to use on a billet crank
Any one use this or any other ideas I can go about this problem
Thank you Ari

Kieth Black shop use to sell a press in steel adapter for your needs, not sure if they still do or not. You can try calling them at 562-869-1518 to see if they still offer them or not I bought 6 of them back a long time ago for $25.00 each plus the shipping. I've used them in the past but now with the new stroker crankshafts being readily available and reasonably price for new ones I don't buy any of the used Top Fuel cranks any more

What is the issue with the TF crank,no register for the toque converter? Correct, most of the old Nitro racers had the early 392 type hemi motors a long time ago that had the flywheels fit around the outside of the crankshaft flanges with no provisions for a converter register on the back of them like the new stock wedges and hemi motors made after 1962. They would have crankshafts made for the early type flywheels and clutches instead of buying new ones, some racers are still doing that

I made one of these up, both an alignment ring and distance adapter. It pilots the flywheel and TC and registers in the crank CO' bore

J@W makes a flywheel and adapter
Meziere sells one too
130 teeth gm style flywheel
You can use a stock mini starter
It's the converter that we will see when we get there !

I went down that road over 20 years ago with a 4.5 arm that had the radial cracks.

Yes converters are GM style. I moved the started the right side so there would be less clutter on the left side. it is a GM flex plate with a 8 bolt mount and 6 bolt converter pattern. Used a minnie starter as a mock up starter and then replaced it with a better aftermarket version. Also had to change the pinion gear to a GM tooth count. The full diameter adapter between the crank and flex plate makes up for the .500" thick mid plate so no spacers are needed between the flex plate and converter
