Ah, that's not how I read it at all, and I must have missed the parts on the build list. I'll take your word for it since you've actually seen the car.

Yes the 4.0L keeps the stock bore. There is an option to over bore if you so desire but it is not needed.

The 4.5L is sleeved and yes significant cooling requirements were needed to be put in place. The 4.5L generates a lot of heat! I have somewhere around 3 oil coolers lol and a giant 3" thick racing radiator with larger Spal fans.

Yeah I talk to 1slow370 every other day lol and yeah we discuss his build quite often.
