Ray Barton used to offer 528 (and 572) Hemi's on his website. Single 850 cfm 4 barrel, pump gas, flat tappet, 800 horsepower. Impressive. I'm wondering, why not a bigger carb on a motor so large? I mean a stock 426 Hemi supposedly has 1200 cfm. So a 572 would have to have over 1500 right? So I asked him, why such a small carb? He said, it's because I've never found anybody that can tune a Dominator. I found that interesting.

By the way, you wouldn't want to try to build your engine today. Callies wants $3,500 for a crank and USA made rods are around $2,800. Plus freight and tax of course. So around $7,000. Enjoy your car.
