Hi Jack,
If I remember correctly, it takes around 50-60 hp to turn a TH400 compared to a TH350 that needs 30-40. On the other side of the coin, it only takes 15-20 hp to spin a manual trans. What accessories are you running? That stuff eats hp too. Maybe your engine needs some more tuning or some more miles to give everything a chance to seat. What heads are on your 454?

I just had my 66 dynoed. I had put in a worked 454. The desk top dyno quoted 500HP at the crank.
This was done at 5500 ft elevation.
The results were: 301 HP at the wheels. I was hoping for at least 330HP.
The car has a TH400 tranny.
Does this sound about right to you guys?
How much does the 400 use?
Thanks
