As many of you may know, I swapped. Cadillac 425 in my Monza drag car before I sold it.The 3rd owner swapped in a 472 and sold it again.
Some of my advice came from Cadco , a company that has making Cadillac motors go fast since the 70's.
Well I just found out that they achieved 900Hp at 6500 rpm with a stock block with no power adders at all.
How about that!
