Building 69 383 for my 69 dart.

Thoughts on this build? Lot of power for low compression

I forgot about that piece of crap. It had so much blow-by that we used two pieces of 5/8" hose about 2'-6" long on the valve cover breathers and they would stand straight out horizontal at rpm. Wiped out a couple of lobes on the Hughes cam. Put an old roller cam in it and it made 525 HP. Put a hydraulic flat tappet in it and used it as a mule the first time we set up our new-to-us 901 Super Flow engine dyno. The engine still sets over in the corner under a tarp.
