ok - just got done with my welding bend tests, it was tuff! but now it is time to focus on the yota. I have to good 22R cores. My motor has been in need of a rebuild for a long time. I am considering the 4.3 swap, but really like the idea of just rebuilding the 22R and installing a propane system. The 4.3 swap(rebuilt) and the propane setup with a 22R (rebuilt) would be about the same costs. What do ya'll think and let me know why ....Its allready built(everything but the motor), just needs some go-go....
