my brother has the 347 450hp crate motor. Awsome motor does exactly what they say for power and ran 11.6@119 in a 84 gt with a 750 carb. The car was scaled at 2900 without him in it. The sad thing is that ford raised the price of the engine to over $8000 my brother paid $6100 for it last year from a local ford dealership here in CT.
