I wouldn't say "easy 600", some folks take advertised hp and torque claims waaaaay too literally. The factory ratings for the 68-70 472/500 were 375-400 hp and 525-550 torque when in fact most Cadillac performance experts will tell you that these ratings were grosley overrated.

I just dyno'd my BUILT 507" Cadillac, forged rods w/ ARP cap screw bolts, ported large valve heads...but still 8.7:1 comp., 230/238 dur. 540 lift cam, single plain intake/780 QFT carb, shaft mounted roller rockers....blah blah.

It made 535 ft. lbs @ 4300 and 466 hp @ 5000. I was very pleased with the results for the 8.7 comp. ratio and it made huge amounts of torque right off idle. Here's a few pics, the red line on chart is the torque curve....which really doesn't curve
