The T-34 was originally equipped with an anemic Continental O-470.  To increase performance, reliability, resale value, and strength, we can upgrade your T-34 to the Continental IO-520, IO-550-B or IO-550-R engines.  We remove your original O-470 engine and completely modify the structure of the engine compartment.  This modification removes the old, light weight, 55 year old structure up front and replaces it with new, much heavier duty material to accept the higher horsepower engine.  We have all of the specialty equipment and jigs for an accurate installation.  At this time the engine compartment can be stripped and repainted, and new wiring harness installed.  When comparing the specifications, it is easy to see why this conversion is a worthwhile investment.
