They were stock specs... I believe that is what he was trying to get across. It was only for reliability sake... He did not get any performance benefit except for reliability.

You can do the following and should easily break 400rwhp:

4.0L stroker kit $3-5k
Bare short block (reuse your own)
Jun 282 cams (not sure on price $800?)
Built heads $2-3k
Custom intake manifold $2-3k
Stillen G3 intake $450
Z1headers $800
Test pipes $300
3" exhaust $1200
Lightened flywheel/clutch combo $1000
Fuel system to support the power $1000

Total cost $15k-$20k with labor

Does the 4.0 kit keep the stock cylinder bores, or does it need to be sleeved? The 4.5 needed to be sleeved, right? Isn't that where a lot of the cooling issues popped up?

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.
