LT-4 Kit

Does anyone know anything about the lt4 kit for the lt1 trans am? I know it runs around 2400. Does anybody have it in theirs. Thanks.

Dont have it in mine but it is something I am going to do in the future. But I have heard it's one of the best things you can do. The LT4 Vette did a high 12 with the right driver, and its the same bottom end as the LT1 just the top end was changed. So consider that with any other mods you got. They say its only like a 30-40 HP inrease but really I think it's closer to like 60-70. This is what I have heard anyway. Well, hope this helps.

The Vette would also have been lighter.

I think it was summit that I just read this in, but it said that the kit gives you 425 proven horses. I'm not sure thats's right, but if it is, yeah buddy!
