So, I blew up a 289 with a mild cam and a 4 barrel carb. Floated and dtopped a valve and well...there went the 289. So I got a 94 351w block with roller lifters, put a lunati voodoo cam in it with appropriate parts to support the bigger cam and the 650 carb from the 289. But this motor won't pull like the little 289. I figured it'd fly down the street. It has torque, I'll give it that but no power. I need a valve adjustment and can't get the correct timing until then but will that be my problem? It should pick up a bit of power but 300hp+ like it should?

Welcome to Stangnet!

Tell us more about the 351. Beyond the cam, what mods does it have?

The 650 carb will be enough for a mild 351, but if you done much else, you might need to step up to a 750. Really depends on the supporting modifications though.

Things like new heads, type of intake, ignition system, stock short block or not.

What vehicle is the motor currently in?
