I have a 55.1 235 bored .60. Replaced original head with "848" head off a 56 235. Offy dual intake with water heat and Carter Weber carbs purchsed from Tom Langdon (Stovebolt Engine Company). Fenton cast iron headers. HEI distributor also purchased from Tom Langdon. I purchased a mild cam upgrade and lifters from Patricks. I couldn't be happier with the way it runs. Very responsive. It is everything I had hoped for.
