Re: How much power
The compression ratios did change.I had early[XA/XB] 351 in XD[still have it in back shed] and an XD mill the early mill had more pulling power and grunt down low,The latter mill with better induction sort of made up for it, up top,imo more fuel consumption too. Speeds over 180kph was about it until some mods on both engines. Both std 4 barrels, Square bore / spread bore...2.7 final drive..
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
