Right, a little more expensive because of the piston thing (no V piston use) but I have a couple of cores, lots of speed parts, and I have built more of them than 250's. Hood clearance i think will be fine, but I wanted to hear the ins and outs of the conversion before I started. More for efficiency then anything else. Work does not leave me with much time, if I can sort out the trouble spots ahead of time I can do the swap quickly and have the car back on the road. That would be a huge plus.
