"pretty good engine"? ? ? FYI the 350 Chevrolet originated from a design that first appeared in 1955, so yes, over 50 years before the bailout. The "small block Chevy" is arguably one of the best gasoline engines EVER produced and was produced in larger numbers and more variations than almost anything on the planet. There was only one problem with the original I-6 Jag engine, that was the cost of repair and maintenance. For every 1 qualified, experienced Jag mechanic, there are probably 1000 that are equally or more qualified on the SBC. SBC parts are available ANYWHERE. One could convert to a SBC for 10% of the cost of fixing the Jag Engine and have a reliable drive line AND English classic chassis + Styling.
