i was wondering what a good brand of turbo manifolds would be? possibly better if its ramhorn. recommend something even if pricey. something that can handle around 400 hp.:hammer :: scared:

 

I think the search feature will serve you well here, and Google. Look for quality workmanship and a company that can back their products.

400 is not big power for an H, so you should be concerned with quality and design, and depnding on if you want a/c and power steering, compatibility with those.
