I was wondering the same thing as well. How come I never hear about a 2.9 liter?
Also On the calculater on the link earlier, according to it, you can only run l20a rods with and ld28 crank in a l28et block. Some people have speced their engines to run l24 rods with the ld28 crank in the l28et. Is the calculator wrong? Or is it because you have to modify the pistons?
On the calculater it acts like l14/l20a rods are the same, I have read other threads that claim them to be very different-the l14's being more ideal for a stroker setup.
Someone clear these things up! I'm becoming confused.
