I think in actuality we are all on the same page here. We are all wanting proof! How we will get it I don't know. I may well groove the 4.5L head when the time comes.

Still like to see a true apples to apples test done. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrac II " I realize that death is inevitable.
