Turbo slant 6?

I also used a "U" tube off a stock exhaust manifold on my turbo slant. I used a turbo from a Corvair (slightly modified) in a Draw thru, no charge cooler, water alcohol injection, running about 10 lbs boost.
A stock slant will handle 10 lbs boost as long as you don't run lean, or get into detonation.
PS: Most people don't consider this on a mild turbo slant. Even with a stock cam, use 340 valve springs. Not because of rpm, but because the pressure on the back side of the valve, reduces the effective spring pressure.
