Just put a 408 in and I have a vig 3800. I want to go with a better stall. The vig is eating all my power up. Tuned today I got 455rwhp and 475TRQ. I believe the vig is killing me. what do you think? I also have 12-bolt. Car in sig! I`m going to spray a 200 shot with it also! What you think fellas!!

 

What are the ET245 heads - I don't see them on the ET site...

For a NA 408, those are pretty good rwhp numbers. Did you dyno with the converter locked or unlocked?

U should match ur stall to where u make the power, u should look at ur dyno sheet and go from there.
