Hogan makes a great looking intake! Question: With ports that large what would be the limits of your rpm? You would have to keep feeding that motor with a ton of airflow so that it doesn't run out of breath. What brand is the preferred rocker and lifter, Jesel? On my first twin turbo motor I had 2 Mitsubishi 80mm turbos. The had very large compressor housings and small turbine housings that came from an Indy motor. All of those engine parts were purchased from Bill Tempero, aluminum blocks, cranks and even an off center 4.1 short deck, large bore, short block from back in the day. I will try to dig up some of those pics. I don't know if you remember a guy named Bob Gribble, owner of Muscle Motorsports in NC ( he passed away a few years ago) he used to race Bonneville in a Merkur Xr4Ti with different stage 2 motors and I saw and learned a lot of interesting things also.
