351W----351W HO Difference?
Hi, I own 1990 Ford BRONCO. I have the 351W HO (high output) engine. I was just wondering if anyone knew the diference between the regular 351W and the HO edition. Thanks for the help in advance!!!

351W----351W HO Difference?
I've been told by my local Ford rep that the only difference is higher rate heavy duty valve springs to limit valve float at high RPM. Have a great day! Broncomule
