to determine optimum shift points you need to datalog acceleration rate....the proper shift point is the one that minimizes the loss of acceleration........but if you still have the stock torque converter, i'd definitely keep them below 5400
The advantage I see in spinning it up on WOT past the peak touque is when you shift in to second the motor will spin up quicker. My PI with Jtune shifts at over 6k, torque starts droping at 4500, hp at 5500 but nothing drastic. It goes from 4500 to 6500 in first in a blink of an eye. Second pulls like a MF.
My car revs to 6100 rpm but seeing how the rpm needle's are wrong in these cars it is more like 5400.The car pulls hard all the way to redline which I know is well beyond 5k rpm.Second gear in the car is amazing at high rpms.
Lonnie is the one to ask then, not this board. He will have his design notes on the tune. The other part might be that most of us who actually run these things know, stock tachs are more for fun, not really very realistic!
I was rear ended last night and my passenger side frame rail is buckled. After looking up the current Blue Book I am thinking I might be forced into another car shortly. I will be finding out in the next few days whats going to happen.
Hey guys, it has been quite a while but it's good to be back!
I am in need of some guidance regarding a recent engine swap in my 97 bird.
The back story:
It has been quite a while since I have posted, mostly due to the fact that my motor exploded roughly 6 years ago. Since then the car has...
I've been screwing around with this all day. Short of removing the cam, is there any way to get to the lower head bolts on this car? My socket wrench (all 4 that I've tried) is obstructed by the shock tower. I had a hell of a time removing one of the valve cover bolts on the bottom, but...
Hey guys; I've been posting in a few threads talking about the various mods for our cars, and I thought I'd start a thread where we could pull a bunch or the info together, and link to the various Howto threads.
So, in our best free-for-all fashion, lets discuss the various mods, and kick...

This thread was about a 5.4L DOHC installation that another member was planning to develop as a kit for the Thunderbird. Due to the overwhelming bashing by Jerry's crew the kit was canceled.
Why do you ask this happened. The story...
I was talking with my father the other day about engines, he's trying to teach me the basics and how they work. He's doing a great job of explaining these things to me, but now I have a question for you guys based on things that he told me.
Our V8s produce roughly little over 200 horsepower...
