I have a chance to buy an early DeSoto 276 Hemei that has only 12,000 miles on it. It' been stored for 35 years and I pulled the valve covers and heads and the cylinders look good, very little rust and after new gas and oil and filters it started right up with the carb needing a rebuilt . My question is this a good engine to built on. I was thinking of a .060 overbore with better high compression heads and a mild cam along with a dual plane intake and a 600 cfm carb. Stock HP was 160 amd compression was 7.1 to 1. I would like to get around 230 HP and a better compression of 8.5.. I'm not worry about the $$, but dont' know much about these early Hemi. Are modern valve train available for this engine?
