Bought me a 67 Fastback BCUDA

Do some research. Cylinder head airflow makes horsepower. Just compare any small block head, and I mean ANY small block cylinder head, to the gen 3 for flow numbers. It's not even close. The early gen 3 is not without its faults. A stock-ish short block is about the same money. But, to put a 280 to over 300- ish intake airflow number on a small block, let alone a FACTORY small block head, good luck. I'm not an expert by any stretch of the imagination on the gen 3's, but, I have some. I have run one 3 years bracket racing. Damn reliable engine. If only the driver were as good as the engine.......
