Twin turbo 400 b block help
Hey guys, I have a 78 400 that I want to twin turbo. I am looking for any recommendations on turbo size. It will be pump gas with stock bottom end. I'd be happy in the 500-600hp range (yes I know that's a good gap). Right now it has an custom ground cam from the 70s (unknown specs) stock heads and a tunnel ram intake. I don't really want to open the bottom end up. I would prefer to use the stock 452 heads with some mild reworking. I'm looking for fun reliable power that won't have a boat load of lag

Hm darn. I was hoping I could squeek by with low boost for a bit hahah. What would the bottom end hold for power? Even if I could get around 400 hp I could settle haha... For now

You'd have to have a lot a faith in the stock pistons, the turbo RV motors from the seventys had very small turbos. Hardly worth the effort.
