Default hf and dx cranks.. Whats the difference

Anyone know what the difference is between the 88-91 crx dx and 88-91 crx hf crankshafts.. They have different part numbers but I dont see what the difference could be between them..

I know some year HF crankpulleys are smaller or lighter, forgot which, but it may be a different end bolt or end diameter or something to that effect?

won't work.

D15 16V uses 45mm rod bearings
HF uses 42mm rod bearings

Also the HF crank is lighter, doesn't have the counterweights.

yes, the main bearings are the same size.

FYI Bisimoto ran a D15B6 block to 10.77 in the 1/4 mile.

Well then the only difference between the b2 and b6 bare block is the engine code stamp on the outside of the block..
