Minimalist Slant Six draw-through build...

Hey everyone. I have a 225 Slant Six with hyper-pak, 500CFM (detuned) Edelbrock, Electronic ignition, 904 Auto & 8 3/4 in my 65 Barracuda. It’s a real clean, rebuilt motor that purrs right now but is low on power due to elevation and, well, because it’s a stock slant LOL

I live at 6200ft+ and decided that my solution for more power will be a draw-through turbo.
Because I’m insane. I just don’t want to cam-out and mill the piss out of a great stock engine if I can do something cool for a bit of power that’s also relatively bolt-on.

It’s a vintage Rajay/Airesearch carbon-sealed turbo with the Mopar RV-style split-plenum manifold, turbo will be rebuilt before run. Manifold has a spring blowoff that will need a redirect pipe because, well, flammable A/F mixture is bad.

SO; here’s my bullet points on what I know I’ll be doing.

• Turbo will be plumbed by T-fitting at oil pressure sender, piped down into upper side of pan for hot oil dump.
• Turbo will be supported by brackets to the motor/mount to keep weight off factory manifold, sitting up forward of intake manifold on J-pipe from the factory exhaust (moving battery to trunk)
• Will pull head and calculate compression, before re-gasketing head with a steel shim style.
• Manifold will have a reed valve set added inside the plenum, to allow for draw-through from carb to intake (bypassing turbo circuit) when under vacuum.
• Will weld-lock a distributor and run a flat (non-advancing) timing, I heard 22 degrees?
• Will run a 2.5” exhaust all the way back, with a glass-pack for minimal back-pressure
• Will run a live AFR gauge & boost gauge, and likely step to EFI kit if I can’t keep consistent ~14:1 AFR under boost (I know it will be rich under aforementioned bypass/vacuum idle, that’s a price to pay)

More advice is welcome... any caveats/horror stories? What else should I do? Am I missing any major steps?

Thanks in advance!
