How many times do you plan on pulling the engine? You should just build a cr right off the hop. You'll have the 24v heads, and complete tunability. It will be easier to light a set of twins too.
Once it goes in its not being pulled. Ill swap stuff with it in the truck. On another note, i dont have the fundage for cr yet. It would have to be down the road. This is my only vehicle so i need to get it running asap
