I'm in the process of building a 84.5mm b18c1. I've been thinking about using a LS crank and rods. I only plan to rev it to 8500-9k. I don't see a problem reving it that high since it will have gsr girdle. I started thinking about this when a local guy did it with a all motor setup and made 215/168 with just street tuning. What do you guys think? Is the extra tq worth the worse rod ratio? Btw this will be a turbo motor.
