its not hard to make an obd2 engine to obd1.
I dont think an LS crank fits in the B18C1 block (but maybe someone will prove me wrong)
So the crank gives the rods a longer stroke? Are there worries of clearance with the valves? Cool new info...thanksIt does. I used an 89mm crank in my GSR block. It's the best way to build a B20/VTEC geometry setup- use the VTEC block and put the longer crank in.
FAR from new information. This has been done for over a decade now.
