Ran one for about 13 years in the 440 I used to have in my GTX. Worked great in that application with 8.8:1 compression (it was a stock 1973 motor I re-ringed and milled the heads on). Low buck, low maintenance, best ET of 12.53 at 108mph. At that time it had an 850 carb, 1&7/8 headers, 4000-ish stall, and 3.91s....but it also had 29.3" tires.
