what's the difference
 

Can any one tell me the exact differences between the 5.0 High Output and the regular 5.0 ??????

RE: what's the difference
 

mostly minor diffences a ho has a double roller timing chain thinner head gaskets diffent came and form 87-95 had the e7 truck heads.

RE: what's the difference
 

And the regular 5.0 on has 150 HP, compared to 205-225 for the H.O.

I think someone once told me that the firing order was different as well, but im not too technical, so i probably have no idea what im talking about.

RE: what's the difference
 

The firing order is different. The "HO" uses the 351W firing order.
