Ohh trust me,,,, I knew that. I wasn't looking at this time anyways. I have to find my 5.4 first. Still looking. But you got me curious. If i had a new harley edition today and i wanted to change the pulley would i need tuning for that?

yes. anything with forced induction, you better get a tune for any and all mods if you want to keep your block non vented.

Thats what i was wondering and what i had always thought but didn't konw for sure. I have been keeping a far eye on the thread about your swap. Have you had it on a dyno yet? I read how you raced the stang.... Some day i want to be there...

I beat a Stang after the big snow storm the other day - I was pulling a wrecker out of the ditch while doing so - The Stang didn't have a chance on ice

That's what "this" trucks for

yeah it was on the dyno with my **** tune, not since its been running right, when is MUCH better, a lot less traction, so it has to be more power... it was 430/512 at the wheels.

Thats awsome. Even on a bad tune that has to be something to look at.

Im glad to see you got it under control. One question for you.... If you have this beautifully built 5.4 and its everything one could dream off... What big plans do you have for your other one?

I am really considering going to a 5.4 in mine. This 4.6 has no anything. My ranger had more power than it

I keep looking at it. And a couple other things. There are two 4.6 4v's within 100 miles of me with less than 80,000 on them ( for less than 500, and one is 399 on ebay). And i also found a 5.4 with 70,000 with out intake.... And we both know hows getting a brand spanking new intake in about three days.... LOL He wants 600 for the block and heads... and The rest of the stuff... Im so drawn in many directions....

What to do???? LOL so many options....
