what year 5.0L or 5.8L

Wow, you guys are really going at it. That's cool, but remember this. A 351W is stronger than a production 5.0 block. The 351W has a better rod to stroke ratio than even a big block chevy. The main caps on the 351W are stronger than the 5.0. Those are the facts. Plus, a 351 can be stroked to over 400 cubes. That's why I went to the 351. Yes, they are heavier and more expensive to dump into a fox body but I bought my car with no motor, tranny, or hood anyway. Unit5302, you are correct about "The 69 351 will require headwork if you expect to unleaded pump gas, a different intake, carb, and a better cam if you really want to make some power with it. When those are performed you're in the same boat as the 5.0. Same mods for significant performance increases." I had to have some work done on my forged pistons b/c of the shorter deck height on the '69. I also got aluminum heads for it. One thing that hasn't been brought up is the fact that the 5.0's need more RPM's to make the power, which in turn is eventual damage and quicker wear. My 351 won't need to see 6 grand to make the HP#s I'm expecting, which in turn means more fun on the street. It's really comes down to affordability and what you want to do. The bottom line is that the 351 is a better choice IF you got the $$$.
