Engine Builders talk.
TBH after looking things up its not that pricey. The problem I found actually deals with the transmission. But I'm not going to give everything up easily. Alot of it would be drivability concerns that a tune could never fix because its completely mechanical.
I still think the best bang for your NA buck is the 5.4 4v with cams, compression and intake. ..maybe even a stroke.
The cost of building a stout shortblock w/ a lightning blower is more expensive.
Either one at 400hp is more than enough to grenade a built factory placed Transmission. There's just less room to grow with the 4v unless you then add F/I. ..but you'd have to think ahead with compression.
