Yes, I believe they are under rated at 1200 hp.

I posted a similar post here https://ls1tech.com/forums/drag-racing-tech/643722-th400-gear-vendors.html . Seems like a few people not recomending them for drag racing but I came out with a more confused impression of why you wouldn't use one..

Your new, so ill give you a little advice, its not very good edicate to "Hijack" a post like that, meaning straying away from the original posters question.

second, there is a lot of good info on this board, and a lot can be found by searching, https://ls1tech.com/forums/search.php?searchid=4639638
there are a few posts there about the 4l80 swap.

Good luck
